With solar power increasing in popularity and use, it can feel overwhelming to have to narrow down the number of solar companies in order to find one that will help with installation— much less narrow down which solar panel manufacturer you want to use. If you’re just starting your search for solar panel companies, we’ve compiled a list of the top solar companies to get you started. Use this list as a starting off point to research companies in your area and then request a quote from a solar panel contractor in your area.

Another approach to finding a solar panel manufacturer is to ask homeowners who have already installed solar panels who they used. Many times, solar contractors have a manufacturer or solar panel brand they prefer. Most people are happy to talk about their experiences with solar and all that they’ve learned, so don’t be afraid to ask questions.

If you’re just taking the first step in researching solar, our solar panel cost calculator can help you estimate how much installing solar energy will cost initially. Knowing this estimated figure will serve as a starting point in your conversations with the solar companies you choose to contact.
