How Delaware works
Why the number is what it is
Delmarva Power serves most of Delaware, with municipal utilities in Newark, Dover and several towns. Delaware is deregulated and procures default supply through Standard Offer Service auctions overseen by the Public Service Commission.
Delaware sits inside PJM, the same wholesale market serving Pennsylvania, New Jersey and Maryland. The 2025 capacity price surge passed through to supply rates across the entire footprint.
The honest cost picture
Two ways to pay for solar
If you buy the system you own the equipment, keep any renewable credits, and carry maintenance. If you use a PPA it is $0 upfront — we install and own the system, you buy the power it produces, and you only pay for what it actually generates.
The residential federal tax credit (25D) ended for systems purchased after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional.
