It’s a common misconception that one solar panel can do it all. While technically it is possible for solar electric panels to create electricity and to heat water using electricity, this is terribly inefficient. Any time energy changes forms, there is an efficiency loss, and in the case of heating water with electricity, the losses are tremendous. That’s why we have solar photovoltaic modules for electricity and solar thermal modules for heating water. Solar photovoltaic modules produce electricity and are approximately 15% efficient using today’s technology. That means for the amount of surface area they consume on your roof, only 15% of the sun’s energyRead More →
