Delaware Solar Market Analysis
Delaware homeowners face electricity rates of $0.18 per kilowatt-hour, making solar an economically sound investment. At the current installed cost of $3.1 per watt, a typical residential system becomes cash-flow positive within 8–10 years after accounting for the 30% federal investment tax credit. With an average of 4.5 peak sun hours daily, Delaware's solar resource supports reliable long-term energy production and meaningful returns on investment, especially for homeowners planning to remain in their properties beyond the payback window.
The state's incentive framework substantially improves solar economics. Delaware's SREC (Solar Renewable Energy Credit) market allows homeowners to earn ongoing revenue by selling credits generated from their systems. The Green Energy Fund rebate program provides additional upfront cost reduction, while net metering policies permit systems to export excess generation back to the grid, with credits carrying over to future months up to 110% of annual consumption. Combined, these programs directly lower net installation costs and accelerate financial returns.
