Energize Delaware helps farmers harness the sun to lower energy costs, improve sustainability, and increase long-term resilience. From rooftop panels to ground-mounted systems, agricultural solar projects can reduce reliance on traditional power and keep your operations running more efficiently.
An In-Home Energy Check-Up is a fast, easy way to increase the energy efficiency of your home and help you start saving immediately. An Energy Advisor will come to your home and check the condition of its insulation, heating and air-cooling system, lighting, appliances and more to identify simple ways to help save energy and money. The process for the check-up includes:
Solar panels use silicon to convert sunlight into electricity. This electricity starts as Direct Current (DC) and is converted to Alternating Current (AC) by an inverter so it can be used in homes and buildings. During the day, panels power your home first, and excess electricity is sent to the grid. Utilities often credit you for the surplus via net metering.
Yes—costs have dropped significantly over the last decade, and financing options plus federal, state, and utility incentives make solar more accessible. If rooftop solar isn’t feasible, community solar is a great alternative.
When properly installed and grounded, solar panels are safe. Local inspections usually ensure compliance. Visit our Consumer Protection page for installer tips.
Solar lowers electric bills, increases property value, and reduces your carbon footprint. If you’re grid-connected, net metering lets you earn credits for excess electricity.
Most systems are roof-mounted, but ground-mounted systems are available for larger properties or where rooftops aren’t suitable.
Panels are rated in watts (W), with most being ~300W. Systems are usually measured in kilowatts (kW). Example: 20 panels x 300W = 6,000W or 6kW.
Add a battery to store solar power for night or outages. Costs range from $12,000–$22,000 and may qualify for federal tax credits.
Choose an installer, confirm your utility’s interconnection process, and use tools like PVWatts or Delmarva calculators to verify system capacity. See our Delaware Solar Installers page
Solar panels are very popular in Delaware! They work year-round, even on cloudy days. Delaware receives more solar exposure than Pennsylvania, New Jersey, and parts of Maryland. However, performance depends on your specific property. Factors like roof angle, shading, and direction can influence energy output.
Before You Install – Compare your solar potential to your past 12 months of electricity usage. Use the tools below to calculate energy production estimates. These are estimates, not guarantees.
PVWatts Calculator – Offered by the National Renewable Energy Laboratory, this tool estimates solar production based on your system’s specs (size, tilt, location). Enter your installation address, adjust settings, and review your estimated annual solar output.

Delmarva Power Solar Calculator – Delmarva Power customers can use this calculator to estimate production, cost, savings, and payback. Enter your address or log in to your account to get started.
You can install solar panels on your roof or property. Be sure your utility allows interconnection before proceeding.
As solar has become more popular and accessible, so has solar advertising and sales activity. Solar can be a great investment, but it’s more important than ever to be an informed consumer. These tips will help you navigate solar offers and avoid common pitfalls.
Tip #1: Always Compare Multiple Quotes
Get at least three quotes before choosing a solar provider. This gives you a chance to compare equipment, financing options, and contract terms—and positions you to negotiate better deals.
Tip #2: Understand Your Financing Options
Whether you purchase, finance, lease, or sign a Power Purchase Agreement (PPA), your choice impacts which incentives you can access and how your system affects your long-term finances. If you own your system, you may qualify for federal tax credits and can sell SRECs. Leased systems typically exclude you from those benefits.
Tip #3: Know the Length and Terms of Your Contract
Before signing, ask:
Tip #4: Pick a Reputable Company
Tip #5: Watch for Common Misinformation
Be cautious of:
Verify all claims with your electric provider, tax advisor, or official solar resources.
Tip #6: Confirm Your Incentives
Estimates for incentives (like tax credits) are just that—estimates. Make sure you:
Tip #7: Understand the Cost Per Watt

Community solar refers to large-scale solar projects—typically 1 to 4 megawatts—where electricity is shared among multiple participants. Unlike rooftop systems, these installations are often located on landfills, fields, or warehouse rooftops, and they allow residents and businesses to benefit from solar without installing equipment on their property.
Also known as shared solar, roofless solar, or solar gardens, community solar opens access to clean energy for a wider range of users
Cost varies by provider, project size, and subscription type. You’ll earn credits based on the actual solar production, which may fluctuate month to month.
Ownership varies:
The asset owner retains rights; the developer handles planning and construction.
Community solar projects require 5–7 acres per MW (20–28 acres for a 4 MW site). Developers may approach you with lease opportunities.
