Solar System for 24x7 Heater Application

Post by ecaits » Fri Jun 03, 2016 7:26 am

I want to use 24x7 DC heater (500 W) by Solar Energy at Gujarat State, India.
How I can calculate the battery bank, solar charge controller, PV Panel etc??

DC heating is a very inefficient way to go. It would take at least 1,500 watts of solar panels to power the system. And the battery bank would be very expensive. You would need about 15,000 watt hours battery capacity to power the heater.

A more efficient way to go is to seal off any leaks in the home/room and insulate better if possible. Then use direct solar heaters to heat the place during the day. Use thermal mass to radiate the heat during the night.
