EDGE Energy installs solar energy systems for homes throughout the Maryland, Virginia and Washington, DC area. At EDGE Energy, we want you to be confident in your decision about installing solar for your home, so we have compiled frequently asked questions to provide you with the answers you need.

How do solar systems actually work?

PV or photovoltaic solar systems are made up of solar panels, racks for roof mounting, electrical wiring and an inverter. From the morning’s sunrise to the evening’s sunset, solar panels generate direct current (DC) electricity which is sent to an inverter. The system’s inverter transforms the DC electricity into alternating current (AC) electricity. This AC power is then delivered directly to the main electrical service panel for use by you and your family at home.

Does shade affect a solar system’s performance?

Solar systems perform best when in direct sunlight. The team at EDGE Energy will evaluate your home’s particular situation to provide a solution for you.

How much can I save with a solar energy system?

The energy use of your household and the size of your home’s solar energy system will be the determining factors in your actual savings. Due to the many financing and incentive options available, there are usually few initial costs, allowing solar systems to start paying for themselves shortly after installation. Homeowners can usually expect to see a return on investment of about 15-20%.

What rebates and incentives are available for solar energy?

There are many financial benefits of going solar today. The federal Solar Investment Tax Credit (ITC) can provide you with a 30% tax credit on your home’s solar system until 2019.

How long do solar systems last?

The SunPower solar panels we install are built and engineered to have a several decade lifespan. SunPower provides a 25-year warranty on every new solar system lease or purchase and includes installation, parts, labor and power. In conjunction with the SunPower warranty, EDGE Energy offers a 25-year warranty on our labor.

Will solar panels increase the value of my home?

According to a recent study by the National Renewable Energy Laboratory (NREL), homes with solar panels appreciated by 17% and typically sold 20% faster than homes without solar. Homebuyers see the value in solar systems, therefore adding value to homes with solar installations.

What makes SunPower solar panels different?

SunPower solar panels convert the most amount of sunlight into electricity, beating other options in the market. These solar panels generate more power in the same amount of space as other panels which are not as efficient, meaning you’ll need fewer of them.
