Actually it’s simple, we use our purchasing power to buy in bulk. We purchase multiple shipping containers full of product which lowers our cost, along with eliminating the middleman and salesperson. That is how we are able to pass that savings onto you.

Most solar installations will require little maintenance during the life of the system, and some proactive care may help you maximize the value of your investment. For example, if you live in a dusty environment, periodic washing of the panels may help increase electricity production.

The lifespan of a solar installation depends on the local environment and the durability of the system you purchase. A high quality solar installation from openbooksolar.com can last more than 30 years.

We are a volume based company and believe every home should have solar and above all it should be affordable for all homeowners.

Solar systems produce less electricity on cloudy days. Homes with solar still connect to the electric grid, drawing power from the grid when needed.

In many U.S. states, including Arizona, there is a policy called "Net Metering" which means the utility company credits a homeowner for solar energy that is not consumed by the home. Those net metering credits are used up when the home takes power from the utility.

We love our customers and our customers love us! We encourage our customers to share their solar experience with friends, family and neighbors and by doing so we reward our customers with a $300 referral bonus! Even if you are not a customer and would like to refer someone that would benefit from solar and they purchase solar through openbooksolar.com you are eligible for the $300 referral bonus! Obviously you cannot refer yourself : )
