Reviews
What customers say
Positive reviewers praise staff for explaining solar and answering questions, while two other customers describe poor communication during installation. One customer said the system began producing power after a crew’s third visit, then went completely down two weeks later. Another said support sent a technician for a battery issue, but that customer had to resolve net metering independently.

Great company to work with! Kyler was very responsive and easy to work with. He explained everything and answered all my questions thoroughly. The install was quick and clean. I’m happy I decided to work with Sun Solar.

Frequently Asked Questions
How long does a residential solar installation take?
The full process can take several weeks, while the installation itself typically takes one to three days.
How is a Tesla Solar Roof installed?
The old roof is removed and Tesla Underlayment is installed before the Solar Tiles are connected.
How does Sun Solar’s power-purchase option work?
In most cases, there is little to no upfront cost; rather than buying the system, the customer pays for its electricity at a fixed or predictable price for 20 to 25 years.
Does Sun Solar provide solar system maintenance?
It can provide maintenance services if needed and recommends regular cleaning and periodic inspections.
