Solcelleberegner

Solar calculator makes it easy to evaluate a solar system — whether you are a homeowner considering investing, or a professional advising a customer.

THE CALCULATOR

Enter annual consumption, kWh price, panels, inverter, roof slope and orientation. Get immediately:

- Indicative annual production in kWh

- Production as a percentage of consumption

- Annual savings in kroner
- Payback period based on your quote amount

SIMULATOR: SOLAR CELLS + ELECTRIC CAR

Visualize the interaction between solar system, home battery and electric car. Adjust inverter, battery, charging power and solar intensity in real time and see how much of the charging is covered by the sun — and how much comes from the electricity grid.

Quickly understand the difference between charging an electric car in full sun vs. at night, and how a home battery can extend the time you drive on your own power.

SIMULATOR: SOLAR CELLS + HEAT PUMP

Understand how an air/water heat pump interacts with your system. Select house size, insulation, COP and solar intensity. See the heat pump's electricity consumption, the proportion covered by the sun, and how long the home battery can cover consumption when the sun is down.

A good tool to illustrate how an efficient heat pump and a well-chosen solar cell system can together significantly reduce the home's energy costs.
