Price overview
What does photovoltaics cost per m²?
The cost per m² depends on module output, component quality, roof type and system size.
These values serve as a guide. The exact price always depends on the specific project.
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.

Accurate planning & quote
The price per m² is better suited for a rough initial estimate. For realistic planning, the price per kWp is usually more accurate.

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?
One square metre of photovoltaics in Switzerland produces approximately 150 – 200 kWh of electricity per year. The exact output depends on orientation, tilt and location.
50 m² → approx. 7,500 – 10,000 kWh annually
Profitability
When is photovoltaics per m² worthwhile?
The more electricity is self-consumed, the higher the profitability of the system.
