For now we have two main renewable technologies that we can set on our roofs : PV systems and solar thermal collectors.
PV systems instead solar thermal collectors produce electrical energy which you can use in much more ways then thermal energy from solar thermal collectors. Thanks to PV you can power your electrical devices, lights or even produce heat.
If you want to calculate how much your client can earn thanks to PV system use our computer app today:
Lack of mechanical parts and liquids in PV systems guaranty us that we won’t have so many repairs as in case of solar thermal collectors. What is more, most of diagnostics we will be able to do remotely thanks to connection with our inverter via Internet.
All those advantages of PV systems make them much more cost-efficient then solar thermal collectors and we should have no problems with convincing our customers that investing in production of electricity from the Sun is much better idea. All you need is some knowledge about both technologies and proper customer proposal.
