FAQ
Are these prices with or without tax credits/rebates?
These are gross install costs — before tax credits, before utility rebates. This equipment does not qualify for federal credits. Check with your utility for possible local rebates.
Can I DIY?
Some homeowners install this themselves, but doing so voids most manufacturer warranties and may violate Mississippi building code / permitting rules. If you self-install, you also cannot claim the federal tax credit on labor costs.
How long should I get quotes valid for?
Reputable installers hold prices for 30-60 days. Beyond that, equipment costs move with commodities.
