The photovoltaic standalone boiler produces more than enough hot water for a 5-person household most of the year. Connecting the photovoltaic modules is very cost-effective as no electrician is required for commissioning. And since no electricity is fed into the grid, the photovoltaic system is also registration-free. Since no mechanical components are necessary to operate the boiler, the photovoltaic boiler is also almost maintenance-free.

The photovoltaic boiler generates your hot water using photovoltaic electricity. Since the sun doesn't send you a bill, you can reduce your running costs for hot water preparation by around 80%. The following text compares the economic efficiency of photovoltaic boilers compared to classic electric boilers. The additional feeding of excess electricity into an 800 W micro PV inverter is also considered. The return on your initial investment is around 25% per year!
