Customer reviews

What our customers say

"I live in an HOA. I found this site when I was doing a google search on how to appeal our HOA's decision that the quote provided by my contractor would require thousands of dollars of modifications! My contractor offered to put me in touch with his attorney. I decided to try to resolve the issue on my own first, so I use this template to appeal the decision. It worked! Sorry for the long review, but I just wanted to share our experience in case it helps anyone else."

- Shelley T.

"I was able to start my company with it!"

- Rian L.

"I truly cannot say enough good things about this site. They are a pleasure to work with every time I inquire with a question. This document was like all the others - perfect! Many thanks!"

- Jonathan P.

"This is my 5th purchase for this site. I'm finally writing a review. The docs have been a huge help to getting my business started. I also like the blog."

- Marvin F.

Clean Tech Docs has been a great resource for our growing solar division. We needed assistance on an HOA document, and they were able to get what we requested within 24 hours! Excellent customer service!

Frequently asked questions

Which states do the documents cover?

Many of our documents come in a California version drafted for California law and a generic version you can adapt to other states. Our HOA solar appeal letters are available for California, Texas and Florida. Each product page says which version it is.

Can I edit the documents?

Yes. Every template is fully customizable, with bracketed fields to fill in for your project. We recommend having an attorney review your finished document.

How does the satisfaction guarantee work?

If you're not satisfied with a document, contact us within 30 days of purchase. We'll correct the situation, give you a refund or offer a credit for a future order. See the guarantee details.

Is this legal advice?

No. We provide legal templates and information, not legal advice, and we are not a law firm. For advice about your situation, consult an attorney. Our Experts directory can help you find one.

Is the forum free?

Yes. Anyone can join the forum for free.

Still have questions?

Contact us or email info@avanticleantech.com. We respond within one business day.

Need more than a template?

Find an independent clean energy attorney

If your situation calls for customized documents or legal advice, our Experts directory lists independent attorneys experienced in clean energy.

We are not a law firm and do not provide legal advice. An introduction to an independent attorney is not an endorsement of that attorney, and we are not a lawyer referral service.

Who We Are

Built for the people building clean energy

Avanti Cleantech began as CleanTech Docs, a library of affordable legal templates for solar and clean energy. Our focus is direct ownership: helping homeowners, businesses, nonprofits, farms, communities and tribes own the clean energy systems they use, and giving the installers and advisors who serve them the documents to do it right. Alongside the templates, we publish plain-English guides on the issues that slow projects down and host a free community where people share what works.
