Sun for the energy revolution

WIRSOL is your partner for renewable energies. We stand for competence,
reliability, independence, quality and service. Together with you, we plan,
finance and install comprehensive photovoltaic solutions of all sizes.


Photovoltaics for commercial and industrial users

The potential presented by the unused roofs of commercial and industrial properties in Germany is huge.
Exploit it – with your own photovoltaic system from WIRSOL! We can assist you with the entire process, from financing and
planning through installation to insurance and service. Get in touch with us, we will be pleased to help you – also if you are
interested in leasing your roof area or obtaining energy straight from your roof!

WIRSOL Solarpark mit Photovoltaikmodulen für die Energiewende mit Erneuerbaren Energien

Photovoltaics for solar farms

Solar farms are the backbone of the energy revolution. As an experienced project planner
and operator in the ground-mounted system segment WIRSOL can provide you with assistance.
Whether expert assessments, project planning, financing, installation, asset management, service
or contract management – take advantage of our experience! Setzen Sie auf unsere Erfahrung!


Photovoltaics for the housing industry

We have already realized projects in the first cities – additional owner revenue generated by solar energy
and benefits for tenants thanks to intelligent tenant electricity projects. WIRSOL ensures that you,
as a tenant, housing association member or home owner, can generate solar energy on your own roof.
We are using our new concepts to bring the energy revolution to tenants!


Did you know that the sun casts as much energy onto the Earth in 20 minutes as the entire world population consumes in one year? This poses the question ‘What is the best way to use this energy sensibly?’ A key element in the response to this challenge is a mix of renewable energies, with photovoltaics playing an important role. This technology transforms sunlight into electricity – without damaging the environment; producing waste or having a negative effect on human health. The sun offers us the means to halt climate change and the consumption of resources.

How does a photovoltaic system work?

Photovoltaic systems are made up of individual solar panels which in turn consist of individual solar cells. When the sun shines, solar cells behave in a similar way to batteries. This incident sunlight is made up of photons, which split electrons, creating positively and negatively charged layers in the solar cell. This difference in potential generates an electric charge. If an electrical consumer, such as a lamp, were to be connected to the cell a (continuous) electrical current would flow. The more sunlight falls onto the solar cell, the brighter the bulb would burn.

Did you know?

In full sunshine...

In full sunshine – on average just under 1 000 watts per square metre in Central Europe – radiance of approximately 10 watts falls on a 10 × 10 cm solar cell. Depending on its quality, a cell of this kind can deliver an output of 1.0 to 1.6 watts. This output increases when several solar cells are combined to form a Panel.

The maximum performance of a photovoltaic system ...

The maximum performance of a photovoltaic system is calculated in kilowatt peak (kWp) or megawatt peak (MWp). This performance is, in theory, unlimited since an infinite number of solar panels can be interconnected. In practice, the maximum performance of a system depends on the amount of local solar radiation and the surface area available.
