18.7¢average home price per kWh (EIA, August 2026)
Strong case for solarAn open state grant, net metering at the supply and delivery energy rate, and no sales tax make home solar work here. Power prices are moderate (about 18.7 cents/kWh), and SREC value depends on winning a yearly bid.

Net metering Net metering available

Extra power you send to the grid earns credits worth the per-kWh parts of your supply and delivery charges (not fixed monthly charges or societal benefit charges). A 2026 law (SB 239, signed June 10, 2026) says leftover credits at the end of the yearly period carry over instead of being lost, and residential customers pay no more than $200 for a new net meter. You keep your solar credits (RECs) unless you sign them away. Source

Solar credits (SRECs) Limited

Delaware SRECs are mostly bought through a yearly SREC procurement run for Delmarva Power and the Sustainable Energy Utility (Energize Delaware). Owners or installers bid; winning bids get a long-term contract. The 2025 round was open November 3-14, 2025. Prices are bid-based and not guaranteed; grant recipients may have to assign SRECs as a condition. Source

Solar laws

  • SB 239 (85 Del. Laws c. 288), amends 26 Del. C. 1014 (2026). Excess net metering credits carry over each year; credits valued at per-kWh supply and delivery charges; residential net meter cost capped at $200; no standby fees on net-metered customers. Source
  • 25 Del. C. 318 - solar on residential roofs (2019). Deed covenants or HOA rules that ban roof-mounted solar on homes are void (2009 law, strengthened by HB 65 in 2019); reasonable placement rules are allowed. Source

Community solar

Allowed by state law but few projects; a sponsor said in March 2026 that developers avoid Delaware because of grid hookup backlogs.

Timeline

  1. Law voids HOA/deed bans on roof solar (25 Del. C. 318)
  2. HB 65 extends roof-solar protection to older covenants
  3. 2025 SREC procurement opens (closed 2025-11-14)
  4. Federal 25D home solar tax credit no longer available for new systems
  5. SB 239 net metering changes signed
  6. Green Energy Program grant set at $0.80/W, max $10,000 (Delmarva)

Federal tax credits

The 30% federal tax credit for homeowners who buy solar (Section 25D) ended for systems placed in service after December 31, 2025, so buying no longer earns a federal credit. If you lease or sign a power purchase agreement (PPA), the panels belong to a company that may still claim a business credit under federal deadlines that tighten through 2027. Ask your installer whether that savings is in your price.
