Understanding units
Why is it often not calculated in m²?
In practice, photovoltaics are usually calculated in kWp (kilowatt peak), because modules have different outputs, roof areas are differently usable and efficiency varies by technology.

Cost factors
What factors influence the cost per m²?
Roof type
A flat roof is often cheaper to install than a complex pitched roof.
System size
Larger systems are usually cheaper per m² due to economies of scale.
Module quality
Premium modules cost more but often deliver higher output per m².
Installation effort
Difficult roofs or additional work increase the price significantly.
Electricity production
How much electricity does 1 m² of photovoltaics produce?
On the Swiss Plateau, one square metre produces approximately 146.2 to 153.8 kWh per year.
65 m² → 9'500 to 10'000 kWh annually
Profitability
When is photovoltaics per m² worthwhile?
The more electricity is self-consumed, the higher the profitability of the system.
