Photovoltaics
Solar power from your own roof — planning, installation and commissioning from one source.
System variants
Rooftop photovoltaic system
Standard PV modules on pitched or flat roofs — the classic solution for self-consumption.
With battery storage
Generated power is stored and used in the evening — noticeably increases your self-consumption rate.
Combined with a heat pump
Solar power and a heat pump together form a highly efficient energy concept for the whole house.
Your benefits
Everything from one source: planning, grid registration, installation and commissioning
Honest assessment of the economics before you buy
Combined with heat pump, ventilation and electrical installation
How it proceeds
On-site appointment: roof orientation, surface area, shading and meter location are checked.
Planning and economics: system size, yield forecast and consumption profile.
Grid operator registration and funding overview, if desired.
Installation of modules, inverter and optional storage by our team.
Commissioning, metering concept and a full briefing with documentation.
How to prepare
Useful: a photo of the roof, your annual consumption (electricity bill), the meter location and — if a combination is planned — data on your existing or planned heat pump.
Photovoltaics FAQs
Is my roof suitable?
Orientation (south is ideal, east/west also works), tilt, shading and structural stability are decisive. We assess this on site and tell you honestly what pays off.
Do I need a battery storage system?
Not necessarily — without storage much of the power is consumed directly or fed into the grid. With storage, self-consumption rises significantly. We compare both variants transparently.
What about funding?
For PV with storage there are different funding routes depending on federal state and programme. You can find the current terms at KfW and BAFA — we help you navigate.
Who handles the registration?
We register the system with the grid operator and handle the Marktstammdatenregister documentation.
