SMA, a company focused on solar energy, is carrying out a project to manage at the same time the electricity and heat consumption in a house combining photovoltaics, CHP plants and heat pumps. Its name is PV-KWK.
The project is based on a modular system of installation and different CHP plants and heat pumps technologies as well as electrical and heat storage will be used to find the best possible combination.
The intelligent system that coordinates all the installation can compensate the differences of power supply from the photovoltaics and the necessities of heat inside the building.
PV-KWK will cost about €5,5 million and will last until 2017. The Education and Research Ministry of Germany has collaborated with €3 million to this project.
