The surplus electricity is stored in a battery
On the south side of the garage’s roof, the photovoltaic modules are encircled by Steni Protego, installed alongside the edges of the roof. On the north side, there has only be used Steni Protego. This is due to the fact that the sun’s rays do not hit this part of the roof as much as on the southern side.
“The glossy surface of the garage’s roof fits really well with the roof of the house, which is made from black glazed brick,” says Jørgen Zangenberg.
He has decided to go with a hybrid solution where the surplus electricity produced by the photovoltaic modules is stored in a lithium battery. This makes the family almost self-sufficient when it comes to electricity. In total, the roof will be able to produce up to 3,500 kWh per year.
“In Jørgen’s case, the roof of the house was not due for a renovation in the near future. The solution that Jørgen instead chose to go with can be an inspiration to others who want to save money on their electricity bills but for who it doesn’t make good sense from a financial perspective to put up a new roof,” explains Thomas Petersen, CEO of Solartag, and continues:
“A lot of garages have worn out roofs, and this can lead to a guilty conscience and expensive maintenance work. By changing the roof and installing roof-integrated photovoltaic modules, you don’t just end up getting a roof that doesn’t require maintenance and has a 40-year warranty period. The money you save on electricity also eventually pays for the new roof on the garage.”
