I volunteer at a food back that had solar installed 1.5 yrs ago. There has been things that broke. We have called them multiple times and they were rude and things are still not repaired. Would not recommend this company to anyone.

Frequently Asked Questions
What does Marks Solar need before preparing an estimate?
The estimate process starts with a request and 12 months of electricity bills, followed by a property visit.
How long does a Marks Solar installation take?
After an estimate is agreed, completion generally takes 3–4 weeks. Installing 25–50 panels generally takes 2–3 days; 50–100 panels generally takes 10–14 business days.
When can a Marks Solar customer expect solar power to turn on?
A building-department inspection takes place after installation. Once it passes, the power company can take 5–7 business days to turn on solar power.
Do Marks Solar's panels provide backup during a power outage?
The panels do not store or back up power. During an outage, power turns off as a safety precaution because the system cannot feed power to the grid.
What does Marks Solar recommend if a roof needs replacing?
Marks Solar recommends reroofing before installation when a new roof is needed soon. For a later roof replacement, panel removal and reinstallation have a minimal cost.
