  • Own production approx. 5,300 kWh/year
  • Surplus fed to the grid (net billing)
  • Additional savings with a battery
  • EV charging for free (eco-smart charging)
7-8 years Return on investment
Cost of a 7 kWp installation: approx. 28,000-35,000 PLN. With savings of 4,500 PLN/year — payback in 7-8 years.
  • 3-8 kWp — residential installations
  • 25-30 years of reliable operation
  • Property value increase of approx. 12%

Benefits of solar panels

A solar installation is not just lower electricity bills — it is a complete change in the way you manage energy at home.
01
Your own electricity
Solar panels produce electricity all year round — even on cloudy days. Surplus is fed to the grid or stored in a Sigenergy battery. All year round
02
3,000-6,000 PLN savings
The average family saves this much per year on electricity bills after installing solar panels. With rising energy prices — more every year. Per year
03
EV charging for free
Connect the solar installation to a Wallbox charger. Charge your car with your own solar electricity — cost: 0 per daytime charge. 0 / session
04
Payback in 5-8 years
A solar installation pays for itself in 5-8 years and operates reliably for 25-30 years. Property value increase of up to 10-15%. +10-15% property value

Factors that shorten payback
  • My Electricity 6.0 subsidy — up to 6,000 PLN for a solar installation
  • Thermo-modernisation relief — deduction of up to 53,000 PLN from tax
  • Battery — higher self-consumption, less energy from the grid
  • EV charging — own electricity instead of more expensive grid energy
  • Rising energy prices — every price increase speeds up payback
  • Municipal and regional subsidies — regional environmental funds, local programmes
