Frequently Asked Questions

What is the warranty on my solar system?

Sunvalley Solar Inc provides a 10 year workmanship warranty for your solar system. The panel manufacturer carries a 5 year panel warranty and a 25 year performance warranty.

How do I maintain my solar system?

We recommend the panels to be washed with water every six months. If there are any technical problems with the system, you may contact us for a checkup.

What are the environmental benefits of a solar system?

Going solar will lower the demand for utility companies to burn coals to generate electricity. It will lower the amount of C02 in the atmosphere and help create a green environment for your community.

What are the economic benefits of a solar system?

A solar electric system allows you to generate your own electricity from home without having to rely on the local utility company. It will also protect you from future utility rate increases for the next 25+ years.

What is the federal tax credit for residential solar systems?

According to the Federal Energy Policy Act of 2005, a taxpayer may claim a tax credit equivalent to 30% of the after state rebate price for a solar electric system. You may receive the full amount of the tax credit during the following tax season (or up to 15 years until the full amount of the tax credit is received).
