Electricity and heat from one module: 2Power

Electricity and heat from one module: 2Power

In the summer months, photovoltaic modules heat up to 80 degrees Celsius. It therefore makes sense to use this energy as well (for power generation). With the 2Power, a solar fluid flows through a full-surface heat exchanger located on the back of the module. The liquid heats up and releases this energy again when it flows through the heat exchanger in the stratified storage tank. A pump causes the liquid to circulate dynamically between the module on the roof and the storage tank.

 

Product Benefits

In the past, homeowners who wanted to generate both electricity and heat on their roofs needed two independent systems – one to produce solar thermal energy, and one to generate solar power – resulting in a busy-looking roof and a lack of space. Most therefore faced a choice between using their roof space to generate either electricity or heat. 2Power combines both solar power and solar thermal energy. It works on the dual principle of generating electricity and utilising heat to achieve maximum energy yield.
