The possibility of changing the number will be introduced in the next update of our system!

06) Team management

The invitation for a new user is sent by the administrator / account owner after logging into EasySolar. The employee opens his account only after receiving the invitation. He has to use a special link to the website through which he will create a new account. Then he will be automatically added as an employee of our company.

Below is a screenshot of the message that the employee who received the invitation to the company will receive.
Number 1 – your’s company name; number 2 – button which employee should use to create new account.

After registering, the employee logging in to the account for the first time will receive an invitation to the company that must be confirmed. After this action, the user will be added as an employee of our company.

If an employee created an account earlier (before being invited), an employee must contact us by e-mail to change the company to which he is assigned in the system.

First of all, check whether the purchased subscription version allows you to add another employee (with the basic version, we can have a maximum of 2 users; if the application is used by 3 users, you need to buy access for another person)

Next, check whether the new user has been sent an invitation from the administrator / owner account.

If the employee has been sent an invitation, appropriate information will be displayed in the employees tab – “pending”.

After accepting the invitation and creating an account, this information will no longer be displayed.
The process of creating an “by invitation” account has been explained above.

If an employee claims that he did not receive the invitation e-mail, it is worth checking the SPAM folder.

There is no limit of users / employees that belong to the company.
The number of people in the company who simultaneously use the program depends on the payment due for the appropriate number of employees.

Most likely, users have Administrator settings or have had their permissions changed to access all clients.
The setting can be changed from the main owner account after logging in in the “Employees” tab.

In our application, users can have three different access profiles to their account.

We can distinguish:

  1. Owner role – the person who created the main company account,
    • makes payments for access to the application,
    • invites new users to his company in the application,
    • the owner has access to the company’s settings (e.g. logo change),
    • can change the access profile for the Administrator and Employee,
    • has the ability to assign individual clients to Administrators and Employees,
    • has access to the company’s warehouse of panels and inverters – adding new items and editing existing ones,
  2. Administrator role – a user who is “under” the Owner, but “over” the Employee,
    • can invite new users to the application,
    • can change the settings of access to clients and panels / inverters for an Employee,
    • has the ability to assign individual clients to Employees,
    • has access to the company’s warehouse of panels and inverters – adding new items and editing existing ones,
    • he cannot change the role and access for his account.
  3. Employee role – user with the least access to settings,
    • the Employee does not have access to the list of other Employees in the company, and therefore cannot change the access settings for other users,
    • has access only to selected or all customers for whom reports are prepared (depending on the Administrator or the Owner),
    • access to the database of panels and inverters also depends on the obtained permissions,
    • it is not possible to add new and edit existing panels and inverters,
    • cannot assign other users (regardless of their role) to clients,
    • all new clients and projects are visible to the Administrator and Owner.

07) Customer and project settings

An example of adding a new project to the client is presented in video below.

The client’s address and the project’s address, although they are usually the same, when editing one of these values, it is important where we edit it.

When creating the first and subsequent project for a client, the address in the project will be copied from the Details tab.

Please note that when editing the address in Details, the one in the Projects tab will remain unchanged, and vice versa. If we want both values to be changed to the new address, we have to do it in both Details and Projects.

In the following video examples, we have shown how it looks in practice.

Video 1

Video 2

Video 1 – changing the customer’s address without changing the project’s address,

Video 2 – changing the project address without changing the customer address.

Such action results from the fact that two different projects with two different locations can be prepared for one client. Then, in the Details tab, the customer’s address is given, while in Projects we have the addresses of individual projects of this customer.

Yes, of course! In this case, open the Add option by pressing the plus (+) in the Project header tab.

Yes, you can do it by opening the menu – clicking the three dots next to the client’s name. (Shown in the video below).

To perform one of the operations included in the question, open the menu in the Project header tab (three dots) and select the option you are interested in. (Shown in the video below).

If, despite the fact that the street is not on the Google map, and we know where the investment will be located, we can place a pin on the map or enter the appropriate geographic coordinates of the object.

If we cannot provide the street / house number, we recommend that you make the above-mentioned proposal.


08) Design the new system

The global database of PV panels and inverters prepared by us is updated twice a year only with new elements. Those that have been added are not removed from it. If you want to use a panel or an inverter that is not in the database, you can add it yourself to your company warehouse.

Such a problem may result from the web browser you are using – we suggest trying another one.
The proper operation of the application may also block cookies saved by the browser. The link contains information on how to delete cookies: https://pomoc.home.pl/baza-wiedzy/jak-wyczyscic-pamiec-podreczna-i-pliki-cookie-w-przegladarce.

Above 90 degrees, there is a blockage due to algorithms that are not adapted to counting the yield from panels turned to the north. At this point, it is not possible to position the panels this way. We are trying to fix this problem and we will try to improve it in the next update of the application.

Meanwhile, the solution could be to set the azimuth in the other direction, e.g. at -89 degrees – the yields will be minimum higher.

The ability to zoom in / out of a photo from Google Maps is in the lower left corner.

This problem may also result from the web browser you are using – we suggest you try using a different one.

Using drone photos (Bird’s-eye view) to design installations is a feature we are currently working on. We know that it will greatly improve your work in preparing offers for clients.

Until then, the design in the photos is not suited to design on flat roofs.

We suggest that you try to position the panels “manually” in the program, i.e. upload a photo of the roof, and then design one row of panels. Copy it one by one and set it yourself at the appropriate distance.
You can also use Google maps and design panels in the place where the object stands or is to be built. In this way, we will be able to perform further activities related to creating a project for the client.

When drawing the roof area, the entire roof must be selected, while when adjusting the perspective, you can create a grid with a maximum size of 50 x 50 meters. The program will automatically generate photovoltaic panels on the entire roof slope thanks to the fact that in the first step we marked the entire roof area (described example is shown in the video below).

The total length of the roof on the above building was 70 meters. Due to the perspective grid, the max. 50 meters, we had to adjust the perspective accordingly.

You can also create a visualization for half of the roof. The generated panels of the first part of the roof can be copied to the second part, thus creating panels on the entire surface that we have to use

09) Design

To do this, open the created project and then select the Design the System tab. Next, we choose whether we create a visualization using sloping roof photo perspective of the object or aerial view using Google Maps.


Aerial view is an option we are working on! It will be available soon.

Category: 09) Design

Instructions of designing PV panels on the example of a sloping roof based on a photo of the building.

1. Create new project and then choose Create new design on: Sloping roof photo:

2. Select the photo on which you make the project. The application automatically begins the Draw areas process on which we would like to create PV panels.

3. Define the area by clicking on the vertices of the surface you are interested in.

After designating the surface on which the panels are to be located, we can proceed to the next step – Adjust perspective.

4. Adjust perspective.

When you switch to Adjust perspective, the blue perspective grid appears. It should be arranged in such a way as to reproduce the arrangement of the roof in the photo, and also to provide known dimensions, e.g. the height of the roof and its length. It may also be a skylight or a known number of tiles of known size. The grid lines reflect the orientation of the panels on the roof.

To be sure that the panels will be generated evenly, you can arrange the grid lines to coincide with the line of the tiles.

At this point, we also recommend that you read the instructions on Adjusting the visualization perspective in the photo of a pitched roof available here.

5. Generate panels and Area settings.

In this step, on the right side, first of all, select the model of panels to be placed on the roof (1), set the Tilt of modules (2), the azimuth of modules(3) and change the orientation of the panels (4). If you make a mistake, you can go back to the previous steps to change your perspective, for example.

If you need high accuracy, the drawing can be zoomed in or out using the “+” and “-” buttons or by using the mouse scroll.

The dependence of the angle of inclination of the panels and azimuth setting the total power production has been described here.

When selecting the model of panels, you can use the extensive database of manufacturers in the public warehouse (1), and also add your own panel (3) by specifying its basic parameters. All added items are in the company warehouse (2).

It should be remembered that only a user with administrator permission can add panels to the Company warehouse and that person can set access permissions for employees, i.e. they can only have access to the Company warehouse or to all panels of the public warehouse.

After choosing Generate panels, the application automatically takes us to the Editing layout.

6. Edit layout.

The Edit layout option allows us to undo or restore (1) the movements made, move the photo (2) on which we make the project, select multiple panels (3), duplicate selected panels (4), delete selected panels (5). The application also shows us how many panels we have used and what power we are able to generate from them (6).

Select multiple panels (3), we can select some cells and then duplicate (4) or delete (5) elements. Having selected panels, we can freely place them on the roof of the designed building. To deselect a given panel (s), having the option selected, select multiple panels (3), you need to deselect each panel one by one; while having selected panels without selecting multiple options (3) just press anywhere in the photo.

It should be remembered that after each editing of the position of the panels and / or changing the parameters, the panels must be regenerated by Generate panels.

7. Save the project.

When saving, remember to crop the photo properly. The application saves the project as it was left when it was created. For a better visual effect, it is best to properly zoom in and center the image

This was the last step of the design instructions in the photo of the pitched roof. The next stage of the project is its valuation, which is discussed in a separate instruction here. If you still have problems with creating your projects, please contact us using the Chatbot (bottom right corner), watch one of our guides here or arrange a free online training: link.

The photo used for the project is a project of an external company: https://www.archon.pl/projekty-domow/projekt-dom-w-jablonkach-4-p-m3512263ccce00

In this case, creating a perspective depends primarily on the shape of the roof on which the installation is designed.
In the instruction below, we present our propositions of perspectives depending on the type of roof we are working on.

1. Triangular roofs.

*) The first suggestion is to use the entire length and height of the roof.


After entering the dimensions, we line up the perspective grid lines so that they align with the line of the tiles. After setting the line, we will most often get a parallelogram (only in the photo, in fact it is a rectangle) described on a triangle if the photo is taken at an angle, or a rectangle described on a triangle if the photo is taken straight ahead. When setting the perspective, it is possible, and sometimes it is advisable, to go beyond the roof with the rectangle.

*) The second suggestion is very similar to the first with the difference that we need the half of the roof and the height.

We set the dimensions and grid lines again according to the tile line. After the operation is completed, the side edge of the roof should form the diagonal of the perspective rectangle. When setting the perspective, it is possible, and sometimes it is advisable, to go beyond the roof with the rectangle.

*) The third suggestion is to set the perspective rectangle to any rectangle on the roof, e.g. a window, a characteristic feature of the roof, a specific number of tiles.

In the photo above, we adjust the perspective to a specific number of tiles, the size of which we know, which will allow us to provide dimensions.

2.  Trapezoidal roofs

*) The first suggestion will be to adjust the perspective grid to the shorter, upper dimension of the roof and its full height. This method allows the greatest accuracy and in most cases is the simplest, because at shorter distances we are able to set the perspective grid more accurately. After specifying the dimensions, set the mesh so that its lines coincide with the line of tiles or some element of the roof.

*) The second suggestion is to use the longer bottom edge of the roof and its height. After entering the dimensions, we line up the perspective grid lines so that they align with the line of the tiles. When setting the perspective, it is possible, and sometimes it is advisable, to go beyond the roof with the rectangle.

*) The third proposition, as in the case of triangular roofs, will be to set the perspective grid to a certain object on the roof, eg a specific number of tiles.

3.  Roofs with complex slopes

*) The first suggestion for placing a perspective on the above slope is to define a grid based on the short upper edge and the full height of the roof. The biggest problem in this case may be a good representation of the length of the upper edge on the lower edge, but if we match the grid lines with the line of tiles, it will automatically have the appropriate length.

*) The second suggestion to place a Perspective Grid for the present roof is to use a longer length and the height of the lower roof to the neck. This allows us to slightly shorten the mesh by almost half its height and the possibility of more precise matching of the mesh line to the line of tiles. In this case, we need to extend the grid line beyond the panel distribution area. In perspective, areas of the grid may intersect, which is not possible when selecting areas for panel distribution.

*) The third suggestion is to set the Perspective Grid based on the length of the bottom edge of the roof and full height. As in the previous example, we need to go beyond the roof area and cut another perspective area.

*) The last suggestion, as in the case of other roofs, is to define a perspective grid on an area that is a characteristic part of the roof or a certain number of tiles with known dimensions.

Depending on changes in the azimuth and angle of inclination of the panels are presented in the following instructions.

1. Change in total annual production depending on the azimuth change.

The reference production level is the total annual production with the azimuth set to 0 degrees and the slope angle of 25 degrees.
During tests, we maintain a constant distance between panels, a constant angle of inclination and a constant power value under steady conditions.

As you can see in the graphic above, our reference output is 16,396 kWh (Szacowana produkcja roczna). In the following sections, the photos will present the following values of the deviation from the azimuth towards the west in steps of 10 degrees.

1.1.The azimuth of the panels 10 degrees

1.2. The azimuth of the panels 20 degrees

1.3. The azimuth of the panels 30 degrees

1.4. The azimuth of the panels 40 degrees

1.5. The azimuth of the panels 50 degrees

1.6. The azimuth of the panels 60 degrees

1.7. The azimuth of the panels 70 degrees

1.8. The azimuth of the panels 80 degrees

1.9. The azimuth of the panels 90 degrees

In conclusion, we see a clear decrease in power along with a stronger deflection of the installation from the south (or north depending on the hemisphere). The entire summary is presented below in graphic form.


Lp.
Azimuth [stopnie] Annual production[kWh]Decline in production[kWh]
00163960
1101637026
22016292104
33016166230
44015999397

66015573823
770153331063
880150881308
990148511545

As we can see, to some extent the change in azimuth does not cause significant changes in the total annual production.
For example, changing the orientation of the panels relative to the south by 10 degrees causes a decrease in production by 15 kWh, but a change by 30 degrees already causes losses of 230 kWh, and a total change of position to the west direction is 1.55 MWh loss.

2. Changing the angle of inclination of the panels relative to the sea level.

In this section, we will discuss the change in total annual output relative to the change in the angle of inclination of the PV panels.
As a reference level, we will take the flat position of the panels, i.e. the angle of 0 degrees, no deviation from the south (azimuth 0 degrees) and constant power under steady conditions.
During the tests, the distance between the panels is kept constant and the shading and the area of the panels distribution related to the need for greater spacing of rows with increasing inclination angle are not taken into account.

As we can see, our reference production is 14 730 kWh (Szacowana produkcja roczna). In the following sections, the photos will present successive values of the tilt angle, changing in steps of 5 or 10 degrees.

2.1. The angle of inclination of the panels is 10 degrees

2.2. The angle of inclination of the panels is 15 degrees

2.3. The angle of inclination of the panels is 25 degrees

2.4. The angle of inclination of the panels is 30 degrees

2.5. The angle of inclination of the panels is 35 degrees

2.6. The angle of inclination of the panels is 40 degrees

2.7. The angle of inclination of the panels is 45 degrees

2.8. The angle of inclination of the panels is 50 degrees

2.9. The angle of inclination of the panels is 60 degrees

2.10. The angle of inclination of the panels is 70 degrees

2.11. The angle of inclination of the panels is 80 degrees

2.12. The angle of inclination of the panels is 89 degrees (it cannot be 90 degrees)

Lp.Inclination [stopnie]Annual production [kWh]Decline in production [kWh]
10147301783
21015613900
31515952561
42016214299

1160153381175
1270143112202
1380130053508
1489116294884

As we can see, the values of the total annual production reach the highest value at the angle of inclination equal to 35 degrees. However, a setting between 30-40 degrees does not generate much visible losses in the total annual production. On the other hand, it is clearly visible that the inclination angle of less than 20 degrees and greater than 60 is unfavorable due to the fact that the annual losses there are already greater than 1 MWh.

When creating a visualization on a sloping roof or using Google maps, the user can use the public warehouse database or add a panel by himself in the Add panel option – the function is available only to users with administrator permission! We will be able to use the photovoltaic panels that we have added in the future, because they will be stored in the company warehouse.

To add a panel to the application, we need the basic rating parameters of the cell so that the program can properly use it in the application.

Category: 09) Design

The minimum distance between rows of PV panels when placed on the ground in an open space or on a flat roof is important to avoid the shading effect.

The choice of this distance is closely related to our geographic location, as well as the dimensions of our panel, its orientation and the angle that makes our panel with the ground. Based on these parameters, we are able to calculate the minimum distance between the panels.

Let’s start with the geographic location. In this context, the height of the sun’s elevation above the sky is important – as we know, it is the lowest on the winter solstice, i.e. on December 22. Now, depending on the geographic location – the hemisphere, zone and the exact location expressed in degrees, we can calculate the height of the sun.

The next step is to calculate the height of our panel. For this we will need the angle of inclination between the panel and the ground, as well as the length of the panel. Of course, knowing the specific measured height makes it easier, but unfortunately at the design stage we rarely have such information.

We use the law of sines to calculate the height:

L/ sin90  =  h/ sin(a)

By transforming,

h= (L / sin90) * sin(a)

Knowing the height and angle of the sun’s elevation, we can determine the minimum distance between the panels:

D= h / tan(Hs)

In the next update of our application, we will introduce a calculator that will allow and facilitate the calculation of the minimum distances between panels for any place on Earth!

Yes, but only when designing by selecting the Photo of a Sloping roof option (having a photo of the roof).

Category: 09) Design

Information displayed by the application when we want to save the project.

Most likely, the project has another surface drawn on which no panel has been generated. You should go back to the Draw areas step and delete the unnecessary surface.

Returning to the Draw areas tab, we can see that we have created a surface that is too narrow for PV panels to be generated on it. The program does not allow you to save a visualization with no generated panels on any surface.

We need to delete this surface and then we can save the visualization.

Category: 09) Design

Using the EasySolar application, you can add e.g. three visualizations for three different directions of the house roof.

If, for example, three visualizations are added, the program automatically counts the power and number of panels that have been prepared.

Category: 09) Design

If you are designing your installation using Google Maps and the graphics quality is poor, unfortunately we cannot help.
The quality of satellite images depends only on the company from which the images come.

The only solution in such a situation is to create a visualization using a photo of the object.

10) Evaluation

If the Evaluate button is inactive, go back to the previous steps in the project.

1. Setting the currency, discount and Tax:

2. Determining the price of the panels:

         The selected panels and their amount are automatically taken from the visualization and placed in the project.
At this stage, we enter the unit net price of the panels provided by the manufacturer or individual (1), specify the Tax (2) and Discount (3). There is also space here to enter additional guidelines or information in the Details area (4).

3. Adding and specifying the price of inverters (optional):

         The inverter we can do by pressing “+” or “Add Inverter”.

        In the inverter selection window, we have the option, as in the case of photovoltaic panels, to add an inverter from our public database (1), and also add your own inverter by specifying its basic parameters (2), after the operation it will be in the company’s warehouse (3).

         Now, just like in the case of panels, enter the unit price and complete the Tax and, if necessary, details.

4. Adding other services performed at the customer’s site (Optional):

         At this step, you will need to enter the name of the service or equipment (1), the number of pieces (2) and the unit (3). In the event of a mistake, you can edit each box at any time or delete the item completely if necessary (5). Adding another record is done with “+” (4).

* ) Setting the amount for the entire offer

         When performing the valuation, it is possible to skip steps 2-4 and set the amount for the entire offer for each 1 kWp of installed power.
Just select “Set for the whole offer” (1) and enter the price per kWp (2) and Tax (3) and if you select a discount, enter Discount (4). Also in this method of valuation, it is possible to add a comment (5).

5. Summary and saving of the valuation:

         The last step is the project summary (1) which is extremely helpful in determining the unit prices of all items sold. Finally, save the valuaton and return to the project (2) dashboard for financial analysis.

Category: 10) Evaluation
This image has an empty alt attribute; its file name is image-7.png

To do this, open the created project and then select the Valuation tab.

Then we choose whether the offer is to include VAT or take into account the discount and select the currency in which the valuation is to be made.

Next, we define the values of the Items on the Valuation: Panels, Inverter and Other.

The different steps are explained here: https://easysolar-app.com/ufaqs/the-step-by-step-project-valuation-instruction/

Category: 10) Evaluation

When determining the valuation items to be included in the report, it is possible to add inverters. You can choose from a public database (public warehouse) or add an inverter yourself (Add an inverter) by entering its basic rating data needed for the analysis. The inverter that has been added by us will be able to be used again later, it will be located in the Company warehouse tab. Then specify the number of pieces and the net price of the inverter and it will be added to the valuation.

11) Financial analysis

To do this, open the created project and then select the Calculate tab.

Next, we move on to the various stages of conducting the financial analysis of the project being created. In the appropriate fields, enter such information as: Consumer’s electricity bill and price, information on possible crediting of the investment and the amount of the investor’s own contribution. You should also choose the financial analysis model adopted in the project.

The next steps are explained in the question below.

Step-by-step instruction for performing the financial analysis.

1. Fill in the electricity bill and electricity price fields

In the first step, is required to complete the Monthly total electricity bill (1), which is the actual amount payable by the customer divided by two (if the customer has a bill for 2 months). Another thing to consider is the annual percentage change in energy proces (2) and the current Price of electricity (3). The last parameter that determines energy consumption is the daytime and night time consumption profile (4). It tells us whether the energy is consumed only during the day (the slider is moved to the far right) or only at night (the slider is moved to the left). In case of problems, a hint is always displayed at the top, which data currently needs to be completed to perform the analysis.

The Annual change in energy prices (2) is the percentage that we determine in order to determine a more detailed analysis of the money that the customer will be able to save after installing the PV system. The change in electricity prices is the projected percentage increase in electricity prices for households.

The Price of electricity (3) is the gross price with the transmission of this energy. Usually, it is difficult for the customer to determine the exact data of the charges broken down into transmission and electricity costs, so we use the combined price in the calculation to simplify the data that the customer is to provide to prepare the calculation.

2. Analysis model

In the next step, we choose the financial analysis model. To use our model database, just search for it by the name of the country or a specific phrase in the search engine (1). All records meeting the requirements will be displayed below (3). Information about a specific model – discounts, returns, settlements, can be found on the right (4). If you do not find the model you need or want to add your own, just use the “+” button (2) and complete the form. Instructions for creating your own analysis model are shown below.

After this step, we will get a preliminary analysis with graphs.

2.1. Instructions for creating your own financial analysis model.

  1. Name – name of the analysis model to be created, by which it will be possible to search for the given model in the list. The name will be displayed in the database of analysis models,
  2. Tax credits– discounts received by the client for the installation of PV panels (e.g. thermomodernization). We give this discount in % and it is added as a % of the investment costs in the economic analysis, which is then displayed as the received payments,
  3. Rebates -one-off discounts or subsidies provided to the client at the beginning of the investment. The cash grant is deducted as a surcharge in the first year,
  4. Rebater per kilowatt – customer discount for the purchase of energy for the photovoltaic installation. This is the same as the Rabates but in terms of kWp,
  5. Net metering available to fed ratio – expressed in %, the difference occurring as a result of surplus energy production. It informs how much energy we can receive from the grid in the discount model. If we give 1 kWh of surplus energy to the grid during the year, we will be able to get 0.8 kWh from the grid for free, so the ratio will be 80% (for installations with a power below 10kWp and instalated in Poland),
  6. Net metering surplus price – value determined by the network operator with whom the customer signs an agreement on the rate of surplus energy produced,
  7. Green certificate price – we introduce if the client has the so-called Green Certificate, these will be additional income due to subsidies for the generated electricity,
  8. Green energy produced price– a value that determines how much the customer will receive for each kWh produced by his PV installation (it does not necessarily mean selling energy to the grid),
  9. Green energy fed into the grid price – value received for each kWh fed into the grid,
  10. Solar panels degradation factor – average annual decrease in the power of the panels that will be installed to the customer.

3. Określenie kredytowania / leasingu

The final step is to define the loan. To start this operation, you need to change the percentage of Own contribution by moving the slider to the appropriate place (1). The own contribution that the customer must have, as well as the total cost of the installation in the form of initial costs, can be seen on the right (4). If you have decided on a loan or leasing, you need to determine its duration in years (2) and its Rate of interest (3). After setting these parameters, on the right side (4) we will see the monthly loan installment and the total amount that we will pay the lender. All changes in the analysis parameters are visible in the diagram of Production and consumption of energy (5) and in the Cumulative cash flow (6).

You can change the profile in the “Financial analysis” tab, and then use the slider to adjust the appropriate “Day and night electricity consumption profile“.

If energy is consumed only during the day, the slider should be set maximally to the right, and if only at night, the slider should be set maximally to the left. We set the same analogy if the energy consumption profile has a different day to night ratio. In case of problems, a hint is always displayed at the top, which data currently needs to be completed to perform the analysis.

12) Send proposal

The following sections provide a detailed overview of the elements included in the report.

1. Adapting the PV system (Page 2):

         A) Your current electricity bill:

In this section, the customer can see how much he currently spends on electricity in a year (1) and monthly (2), as well as see electricity price forecasts and estimates in 20 years, as well as current CO2 emissions per year.

         B) Recommended size of PV System:

Here, the client receives initial information about the designed system – its power (1) and the roof area occupied (2). It also obtains information about its annual electricity production and the estimated annual production of the installed system (3). We can also see if the system is oversized, perfectly matched, or if its power is insufficient to fully cover consumption.

         C) Energy balance:

In this part, we get information about the estimated system power (1) (how much energy we are able to get from primary energy sources), the amount of electricity fed into the grid (2), it is related to the oversized system or when the user uses the main electricity at night and the amount of energy taken from the grid (3) (the user will have to pay extra for this energy), it is related to the system that does not fully cover the energy demand.

2.  Visualization (strona 3):

In this part of the report, you will find information about the number of photovoltaic panels used and the electricity they generate, as well as all visualizations and concepts created by you.

3. Estimate of a project (strona 4):

At this point, the customer receives a valuation. If you select an amount for 1 kWp of installed power during the valuation, the amounts of individual parts of the installation will not appear in the report, but only their number (as above). To view a specific amount for a product, each part of the system must be accounted for separately.

4. Accumulated cash flow (strona 5 i 6):

In this section of the report, we obtain information on the cash flow in the subsequent years of operation of the installation. The first item is production (1), which decreases each year by the panel degradation factor. The next column is savings (2), which is the difference between your electricity bill without PV (6) and your electricity bill with a PV system installed (7). The next item is received subsidies (3), they are related to the thermo-modernization relief and it is the amount that the customer will receive in the form of income tax refund on installation costs. In the Installment column (4), we see the annual loan installment, if the client decided to take out a loan. The next item is accumulated cash flow (5), they show how much the client has gained / lost since the beginning of the system operation.

The next part of the accumulated cash flow is the chart that shows us the cash flow for each year and is compatible with the table.

15) Other

The application does not overstate the simulation of energy production. The adopted calculations are theoretical based on the assumed losses in the photovoltaic system (cables, dirt, DC / AC conversion), the application is at the level of 10%. The algorithm used in the application is book-based, and the meteorological data is taken from the NASA global database.

Category: 15) Other

The EasySolar application is not a typical Autocad design program that allows you to perform a construction project.

The application is mainly used to perform initial concepts, visualizations and economic calculations needed at the sales stage and is intended mainly for home installations and small and medium-sized industrial installations, including farms – up to about 500 kWp.
