Resources for Residents and Homeowners Assessing Potential Solar Energy Use

Many homeowners are installing solar photovoltaic systems to reduce their energy costs as well as greenhouse gas emissions. There are many things to consider when installing solar such as life of your existing roof, financing, and energy efficiency. Onsite solar photovoltaic (PV) and solar thermal opportunities should be explored after your home is energy efficient.

State Programs

Although Pennsylvania does not offer solar incentive programs for residents at this time, the Philadelphia Energy Authority has a Solar Savings Grant Program which provides support to low- and moderate-income households in Philadelphia to participate in Solarize Philly.

Federal Programs

Solar Thermal Heating

Solar thermal energy can be used for hot water and space heating. This can help save money on utility bills by reducing energy used for heating water.
