Terms & Conditions
Last updated: November 13, 2026
1. Acceptance of terms
By accessing and using this website you accept and agree to be bound by these terms and conditions. If you do not agree, please do not use this site.
2. Use of content
The content and tools on this website are provided for informational purposes only. You may view the site and share your results for personal, non-commercial use, provided you credit the source. Reproduction for commercial purposes is not permitted without written consent.
3. Source material
The figures on this website are built from public sources: solar yield data from the EU's PVGIS and NREL PVWatts, published electricity prices, and the laws, standards and official guidance of each country and US state we cover. Product prices are read from the shops' own pages. The methodology page lists the formulas and sources, and each rules page links to its official source and says what is still being confirmed.
4. Estimates, not advice
This website is an independent, unofficial reference. It is not affiliated with, endorsed by or produced by any manufacturer, shop, energy supplier, grid operator or public authority. Every result is an estimate shown as a range. Your actual savings depend on your weather, shading, mounting, electricity tariff and how you use power. Rules and prices change, and the site may contain errors or omissions.
Nothing on this site is financial, legal, tax or electrical advice. We accept no responsibility for any loss, damage or disadvantage arising from reliance on content published on this site. Before you buy or install anything, check the current rules where you live, your lease or building rules, and your energy supplier or grid operator. Follow the manufacturer's instructions and ask a qualified electrician if you are unsure about your wiring.
5. Products and prices
We do not sell anything. Product names, prices and availability come from third-party shops and can change at any time; the price on the shop's page is the one that counts. Mounts and delivery are usually extra. Any purchase is a contract between you and the shop.
6. Affiliate links
Some product links on this website are affiliate links, for example through the Awin affiliate network. They are labelled where they appear. If you click one of these links and make a purchase, we may receive a small commission at no additional cost to you. Matching products are listed cheapest first; see how we make money.
7. Limitation of liability
This website and its operators shall not be liable for any loss or damage arising from reliance on information provided here, to the extent the law allows. Use this site at your own risk.
8. External links
This site contains links to external websites. We are not responsible for the content or privacy practices of those sites.
9. Changes to terms
We may update these terms from time to time. Continued use of the site after any changes constitutes acceptance of the revised terms.
10. Operator
