Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Adopting solar power lets homeowners lower utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re evaluating if you want to go solar, consider these key factors for choosing an installer.
It's important to hire a licensed solar installer. This help guarantee that the work is done correctly using current installation best practices. Ohio may require a solar company to hold a state contractors' license, but only for commercial work. For home solar panel installations, cities can establish their own licensing or regulatory requirements.
Check TrustPilot, Google Reviews, the Better Business Bureau (BBB), and other review sites to see what past customers are saying about local solar installers. Detailed reviews on these platforms can help you assess a provider's trustworthiness and customer service. Stay away from providers with few or mainly poor reviews.
Call three to five solar companies for free, itemized quotes. The quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps you find the option that aligns with your budget.
Quality solar installations should have strong workmanship and performance warranties. A workmanship guarantee covers any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong guarantees show that a company is confident in its work.
Going solar can help reduce your energy expenses over time. Be sure to weigh these aspects when judging the cost and value of solar panels.

There are many benefits to home solar energy. You can raise your property values, reduce emissions, and qualify for tax benefits. With the right storage equipment, solar panels can also give you further energy independence and offer some protection from power outages.
Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, which means you can reap the environmental benefits and savings of solar energy without having to completely switch over.
You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. The sun shines frequently in German, meaning your payback period could last 17.8 years per 5 kW of capacity on the high end.
While solar energy is a valuable option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, a contractor might recommend other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still lower your emissions and could still qualify for distributed generation or other money-saving programs.
Yes, solar panels can still generate energy during a grid outage. To ensure that your solar system will keep working during a power outage, make sure to choose a quality solar provider and look for a solar system that includes a battery backup.
Solar panels can be more efficient than other forms of renewable energy. They have low maintenance costs and today's systems can work in a variety of conditions.
