General information, not advice
Our guides explain how solar, batteries and tariffs work and show example calculations. They are not financial, legal or electrical advice for your situation. Prices, rebates and rules change and differ by country; check current figures and get quotes from licensed installers before you buy.
Accuracy
We work hard to be accurate and cite our sources, but we can make mistakes. If you find one, please tell us.
Using our content
You may quote short passages with a link to the guide. Please don’t republish whole guides or images without permission.
Links to other sites
We link to the sources we use. We are not responsible for the content of other websites.
