Frequently asked questions
Should I replace my roof before installing solar?
If your roof has fewer than about 10 years of life left, replace it first. Removing and reinstalling an array later commonly costs $3,000-$7,000.
Do I need a permit for solar panel installation?
In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does solar panel installation take?
1-3 days of installation, 6-14 weeks including permitting and utility interconnection. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are system size in kw dc; panel and inverter selection (string versus microinverters); battery storage.
