What to write to us about

• Corrections. If a figure, rule or link is wrong, tell us which page and what you think it should say. A link to a source helps us fix it faster.
• Rule changes. If your state or country has changed its plug-in solar rules, send us the bill number or the regulator's page.
• Our tools. Questions about how a calculator works, or an appliance you'd like to see in the power station finder.
• Brands and press. You're welcome to send product news. We don't sell coverage, rankings or links, and we don't publish sponsored posts.

What we can't help with

• Orders, deliveries, warranties or returns. Please contact the seller or the manufacturer.
• Personal electrical, legal or financial advice. For anything involving wiring, speak to a qualified electrician.

When you email us, we use your address and message only to reply. Our privacy policy has the details.
