Virtually anywhere there is sunlight. It can be a roof of a building as well as an unshaded plot of land. A 1kW photovoltaic installation covers an area of ​​approx. 7 m2. In the case of installation on the roof, its angle of inclination should be in the range of 25 – 60 degrees, and the optimal orientation of the solar panels is the south, possibly south-west, and ultimately south-east. If it is not possible to mount it on the roof, the photovoltaic system can also be installed on the plot or on the facade of the building.
