Great local company

Wonderful office and crew, from start to finish very professional. They were clear in thier communications and expectations, and very good at explaining the entire process. I am beyond happy with our solar systems from 7th Gen, and would highly recommend them without hesitation.

Excellent service and price

Outstanding service and price. Installation was quick and painless. The installer was very helpful and answered all our questions. Great follow up and took care of replacing a defective panel quickly.

7th Generation Solar is a Win-Win for Us!

They got the job done and everyone compliments us on the appearance! We're especially happy to receive the electric bill credit every month. What a blessing in these times!
