Solar Panels FAQs, answered by experts

In most states, solar installers need to be licensed and insured as solar professionals, although some states don’t have specific requirements for installers. You can use our state licensing tool to check if an installer you’re considering hiring holds the proper licensing. No matter where you live, a member of your solar panel installation company must be a certified electrician to connect your panels to your home and the electric grid.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don’t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.
