Corrections. If something here is wrong, tell us. We'll fix it and note what changed. This is the most useful email you can send us.

Questions about your own place. Happy to look at them, though the calculator will usually get there faster and we'll mostly be repeating it back to you.

If you have a system running. Send us your kit, orientation, tilt, and monthly kilowatt-hours. We're building a picture of real California installations, and a dozen of them would be worth more than our one test balcony.

If you're a landlord, board member or property manager. We'd like to know what you're planning to do about these requests, and we'll keep it anonymous if you'd rather. We're tracking this.

Manufacturers. We don't accept review units on terms that involve anyone approving the review first, and we say so on any review of hardware we've been sent. If that's acceptable, get in touch.

What we can't do. Tell you whether your specific circuit is safe — that's an electrician. Tell you whether your HOA will win an argument — that's an attorney. We're a website.
