Solar profitability
Yield, savings, payback and CO₂ of your planned solar plant.
Model calculation – not tax or investment advice
This calculator provides a non-binding, simplified model calculation based on your inputs and documented assumptions. The results do not constitute tax, legal or investment advice and do not replace an individual review by your tax adviser. No warranty is given for accuracy or returns.
In three steps you estimate the yield, savings, and payback of your solar system.
- 01
Choose capacity
Enter the planned system size in kWp and your investment cost.
- 02
Add consumption
Provide your electricity price and the estimated share of self-consumption.
- 03
Review results
The calculator shows annual yield, yearly savings, payback period, and CO₂ savings.
The calculator estimates the economics of your photovoltaic system using industry-standard reference values.
Based on system capacity, the expected annual yield is determined – modelled with a specific yield of around 950 kWh per kWp as an assumption. Self-consumption share and electricity price together produce the annual savings compared with grid supply.
From investment cost and annual savings, the calculator derives a rough payback period. It also reports the avoided emissions via a CO₂ factor, making the environmental contribution visible.
Actual yields depend on location, orientation, shading, and consumption profile and may differ from the model values.
The results are a non-binding model calculation and not a guarantee of yield.
We turn the calculation into a profitable system – planned, built, and operated from a single source.
EPC from one source
Development, construction, and operation come from one partner. This noticeably simplifies responsibility, interfaces, and scheduling.
Up to −50 % power cost
Through high self-consumption you cut your electricity costs significantly and become more independent of price volatility.
Strong guarantees
With guarantees of 10, 25, and 2 years plus branded components, we secure the long-term performance of your system.
Proven experience
Over 1,500 systems built from 0.5 to 100 MWp and more than 10 years of experience in Germany and the Netherlands.
