Solar power plant – is a long term investment that allow you to reduce electricity costs and increase energy independence. However, many home owners are considering: when the solar power plant are starting to pay off and is it worth it to put in place now? In this article, we'll explain return on principles, to what needs attention and how to calculate the actual savings.
1. How much does a solar power plant installation?
Medium-sized solar power plant installation prices in 2025. ranging from 4000 to 9000 euros, depending on the following:
- Electric power (usually 5-10 kW household)
- Selected modules and the inverter quality
- The roof design and installation complexity
This amount can be reduced through national language support, which can cover about 30-40% of the project value.
2. How much savings per year?
Average 5 kW power of solar power plant per year generates about 5000 kWh of electricity. The calculation that 1 kWh costs about 0.25 € (including all taxes) can save you about 1200-1300 € per year.
If part of the energy is used directly, and the rest – of gathering as a service (fps electricity network operators), saving a little due to the fees, but still remains significant.

- What size was the initial investment
- Or part of the energy you take directly, rather than through networks
- The changes in electricity prices on the market
