Solar advice: Match the generator to your needs!
The roof becomes a generator of energy.
Once that is clear, the solar installation can be designed accordingly. An intelligently designed solar generator can provide electricity from March well into autumn. For the winter months, it is always necessary to look for an alternative power source, as PV will not suffice in our latitudes.
4 modules give 1 kilowatt
Four solar panels (60 cells), which is equivalent to roughly six square metres of roof space, produce at least one kilowatt of solar power. Over the course of the year, they produce between 900 and 1,100 kilowatt hours of solar energy.
It really should not be less than 900 kilowatt hours, because the amount of usable solar irradiation in our latitudes is between 900 and 1,100 hours, depending on the region.
Higher yield in the Alps
In the Alps, yields can be around 20 to 30 percent higher: The stronger winter sun, reflecting snow and clear mountain air all improve yields. With new high-performance panels, you can even achieve 1.2 kilowatts from four standard panels, with accordingly higher yields. To produce six kilowatts (6,000 kilowatt hours) you thus need between 30 and 36 square metres of roof space. (HS)
