Questions and answers
Solar, answered with the numbers
Clear answers to the questions homeowners ask most, backed by independent data.
Is solar still worth it in 2026?
Yes. Solar module costs have fallen about 90% since 2010, according to IRENA, and solar is now one of the cheapest sources of electricity ever built. For most homes the payback period is around 10 to 15 years, and panels keep producing for 25 to 30 years.
How much can I save each year?
It depends on your roof, your usage and your local electricity price. A typical household offsets a large share of its bill. Use the calculator above to get a personalised estimate in under a minute.
Do solar panels add value to my home?
They do. A Zillow study found homes with solar sold for about 4.1% more, roughly €9,000 to €25,000 for a typical home in later studies. More than 80% of buyers say energy-efficient features matter to them.
How long do solar panels last?
Most panels carry a 25-year performance warranty and often run for 30 years or more. They lose only about 0.5% of output per year, so a panel still produces around 88% of its original power after 25 years.
What if I cannot pay upfront?
You do not have to. A low-interest green loan often costs less per month than you save on your bill, so the system can pay for itself from month one. We also help you find local subsidies and grants.
Is the advice really independent?
Yes. We are not a hardware brand and we do not push a single product. We compare vetted local installers so you can choose on price and quality, with no sales pressure.
How much does a solar system cost?
A typical home system runs from about €10,000 fully installed, and the price moves with your roof, how much power you use and whether you add a battery. Subsidies and tax deductions can bring it down further. The calculator gives a figure tailored to your home.
Does a home battery pay for itself?
A battery rarely pays back on price alone, but it gives you the freedom to use your own power in the evening, when it is often most expensive, instead of buying it back from the grid at peak rates. A smart battery can even buy cheap power overnight and sell it back in the evening when prices peak. Most people add one for the extra saving, the flexibility and the backup, not pure payback.
Does it matter how my home is heated?
A lot. A heat pump or electric heating can double or triple your electricity use, which means a larger system and much bigger savings. A home on district heating, gas or oil uses far less power, so solar offsets less.
Are there subsidies or tax breaks?
Often, yes. Grants, subsidies and tax deductions vary by country and year and can lower the final price noticeably. We help you find what applies where you live, and our estimates are deliberately shown before any of them are counted.
How do you work out these numbers?
Every figure comes from a transparent model built on public, independent data on prices, electricity rates and solar production. You can read the full method, with every source, on our How we calculate page.
