Dean has connected tens of thousands of homeowners with residential solar installers across all 50 states since 2021, and works directly with installers on pricing and financing.
Lumina Solar, Ipsun Solar, Trinity Solar and Venture Home are the four installers in our vetted Maryland network for 2026. Maryland still pays well, but on a clock: full-retail netting holds while the program window lasts, and SRECs near $30 to $40 only pay once registered, which makes paperwork competence the real product here.

Which utility serves your address decides the math behind every row above. Baltimore Gas and Electric, Pepco, Potomac Edison and Delmarva Power all net exported power against your usage at the retail rate under Maryland’s net metering statute (PUA §7-306), with surplus rolling forward month to month, and the Utility RELIEF Act (HB 1532) closes that full-retail deal to new systems at a 3,000 MW statewide cap or on July 1, 2027, whichever comes first. So the question for each company is not whether it can install in your county but which utility’s interconnection queue it files in and how soon. Ask every bidder to name your utility and the filing date in writing.
