Middletown, Delaware, is one of the fastest‑growing towns in the state, with a population that has more than doubled in the last two decades. Located centrally in New Castle County, just off Route 1 and close to Dover, the area features many new subdivisions and older single‑family homes ripe for solar retrofits. Homeowners in Middletown benefit from Delaware’s strong solar incentives, including the federal Investment Tax Credit (currently 30%), the state’s Green Energy Program rebates, and a robust net metering policy through Delmarva Power. The town’s mix of suburban sprawl and increasing environmental awareness creates a healthy demand for residential solar installations. Competition is growing but still fragmented: you will face national chains such as Sunrun and Tesla, as well as a handful of regional Delaware installers. A focused local approach—emphasizing Middletown’s specific neighborhoods, incentives, and community ties—can give a new business a significant edge.
Starting a solar installation business in Delaware requires navigating several state and local regulations. The most critical is obtaining an electrician’s license or hiring a licensed electrician to handle all wiring and interconnection work. Under Delaware Code Title 24, Chapter 14, any person performing electrical work must hold a license issued by the State Board of Electrical Examiners. Small solar projects (typically residential) can be performed by a licensed master electrician or a licensed journeyman electrician working under a master. Additionally, your business must register with the Delaware Division of Revenue for a business license and a withholding account if you have employees. For residential installations, you may also need a Home Improvement Contractor license from the Delaware Department of Transportation’s Contractor Registration Office. The Town of Middletown requires building permits for solar panel installations, so you must submit plans and pay applicable fees. Finally, to participate in Delaware’s net metering program, you must submit an interconnection application to Delmarva Power, and you will need to set up an account with the Delaware SREC (Solar Renewable Energy Credit) marketplace, administered by PJM Environmental Information Services. Liability insurance (minimum $1 million general liability) and workers’ compensation coverage are mandatory for most contracts.
