Terms and Disclaimer

Last updated October 29, 2026.

Not legal or electrical advice

Our pages summarize laws, costs and setup in plain language. Laws change, and your utility, landlord or HOA may have their own rules. Check the primary source linked on each page and, for wiring, a licensed electrician.

Calculator estimates

The calculator gives rough estimates from the numbers you enter. Real output depends on shading, angle, weather and your equipment.

Advertising and links

The site may show ads served by Google AdSense. Ads don't change what we write. Links to other sites are for reference; we don't control their content.

Use of content

You may quote short passages with a link back to the page. Please don't republish whole pages.
