When the subject of solar energy comes up, you often hear comments about how it would be nice to harness the power of the sun, to be less dependent on the utility company or foreign countries, or to be environmentally sensitive. But, they say, solar technology is still so very expensive. They are right … kinda.
Solar systems are expensive at initial purchase. But high quality equipment is never cheap, and this equipment lasts for decades and will pay for itself many times over during its lifespan. But best of all, there are numerous federal, state and local incentive programs that can substantially reduce your cost of ownership.
The number of federal, state and local programs are many, and in this page we will look at an overview of residential incentives only. If you are a commercial customer, or involved in agriculture, there are completely different programs that we would be happy to go over with you at your convenience.
The following is a high-level overview of federal residential incentives as well as state programs in Maryland, West Virginia, and Pennsylvania. Please contact us with any questions – it is very important to fully understand the financial incentives that are available.

Federal
Incentive Type: Personal Tax Credit
A taxpayer may claim a credit of 30% of qualified expenditures for a system that serves a dwelling unit located in the United States. If the installation is on a new home, the "placed in service" date is the date of occupancy by the homeowner. Expenditures include labor costs for onsite preparation, assembly or original system installation, and for piping or wiring to interconnect a system to the home. If the federal tax credit exceeds tax liability, the excess amount may be carried forward to the succeeding taxable year. The excess credit can be carried forward until 2016. The maximum allowable credit, equipment requirements and other details vary by technology, as outlined below.

Incentive Type: Grant
Maryland's Solar Energy Grant Program, administered by the Maryland Energy Administration (MEA), provides financial incentives to homeowners, businesses, local governments and non-profit organizations that install solar water-heating systems or solar-electric (PV) systems. Both grid-connected and off-grid PV systems are eligible for supportThe current Solar Energy Grant Program (effective for applications received on or after September 1, 2009) provides incentives as follows:
| First 2,000 watts | $1.25 per watt | $2,500 |

| Watts 8,000 – 20,000 | $0.25 per watt | $3,000 |
Based on the above, a typical 4,000 Watt residential system would qualify for a grant of $2500.00 for first 2000 watts, plus $1500.00 for watts 2000-4000 for a total grant of $4000.00

Pennsylvania
Incentive Type: State Rebate Program
Amount: Residential PV $2.25 per watt DC. Maximum is the lesser of $22,500 or 35% of installed costs
The Pennsylvania Sunshine program offers rebates to residential and small commercial residents that install photovoltaic (PV) and solar thermal. It was authorized in July 2008 by the state legislature and began accepting applications in May 2009 under the administration of the Pennsylvania Department of Environmental Protection (DEP). Only systems installed after the date of program opening are eligible for rebates. A total of $100 million (funded through state bonds) is available for rebates over the lifetime of the program. The DEP expects the program as a whole to last three to four years.
All residential applicants must be Pennsylvania residents, own the home upon which the system is installed, and use it as a primary residence (i.e., vacation homes and investment properties do not qualify for residential rebates). Small business applicants must be for-profit entities located within the state of Pennsylvania with no more than 100 full-time employees. This definition includes producers of an agricultural commodity. Low-income residents (60% or less of median state income) are eligible for higher incentives than other applicants.
It is important to note that residents and small businesses do not submit incentive applications themselves. Applications must be submitted on behalf of the applicant by an approved installer. Households are eligible for only one PV and one solar thermal rebate.
