Install Solar Panels or Solar Heating Yourself
How to install solar panels
For residents looking to install solar panels or heating, the Maryland Energy Administration created a booklet entitled, A Maryland Consumer’s Guide to Solar. This booklet is an educational resource for Maryland residents who are considering installing a solar photovoltaic system on their home. As solar PV systems are expected to have lifetimes of 25 years or more, it is important for residents to have a good understanding of all aspects of the decision to “go solar.”
Learn from one resident who went solar by reading their story.
Solar projects require two permits: a building permit (for the attachment of the solar panels) and an electrical permit (for the connection to the home’s electrical service). Properties with an individual well and septic system will have additional requirements. Rooftop solar projects must be applied for electronically. For qualified projects, visit the eSolar webpage for more information.
Steps to Install Solar Panels:
- Use tools like PVWatts® Calculator, SunCalc or Project Sunroof to check if your home is in a sunny spot with minimum shade.
- Have a certified contractor assess your roof or contact Solar United Neighbors of Maryland for further guidance.
- Choose a Licensed Installer: Find a certified solar installer through the North American Board of Certified Energy Practitioners or Roof Integrated Solar Energy.
- Explore financing options for solar panels through Montgomery County Green Bank.
- Consumer financing guide to solar – Read this consumer financing guide created for DC, which provides questions to ask when interviewing solar companies. (Pages 22-24 are especially useful.)
Install a solar hot water heater
Solar hot water heaters are a cost-effective way to generate hot water for your home. Since water heaters account for nearly 20% of household energy use, switching to solar can make a big difference. Learn more about solar water heaters at Energy.gov.
A note from the Office of Consumer Protection
Office of Consumer Protection also has created a page dedicated to solar financing if you have questions about paying for your solar system.
