This was not the first time we have used Diablo Solar Services. We have had an outstanding experience each time they have worked with us! They are awesome! They replaced a solar panel that was more than 10 years' old that had gone bad just because they wanted us to be happy. They were also easy to schedule with as well as easy to work with..They didn't lie to us. They only sold the best. Everything was perfect. We also had them install solar panels on our pool in 2002. They even installed electric solar panels for power. It was a no-brainer.They do weatherization and catch minor leaks that we don't even notice in the summer and winter. They are by far the best. Diablo Solar Services hooked us up with the best package. To date, in the last 5 months, we have had no electric bill! We will continue to use their service.
