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:
Putting solar panels on your roof could reduce your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.
Hiring a licensed solar installer is critical. This ensures that the work is done correctly using current best installation practices. Ohio may require a solar installer to hold a state contractors' license, but only for commercial work. For residential work, cities can establish their own licensing or regulatory requirements.
Check consumer review platforms like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with providers that have hardly any reviews or mostly negative ones.
Get free, detailed quotes from at least three solar companies. The quotes should outline all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.
Quality solar installations should have comprehensive workmanship and performance warranties. The workmanship guarantee covers any installation problems such as cracks in the panels, poor wiring, or poor alignment. The performance warranty promises a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.
Solar energy can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.
In London, solar panels cost an average of $3,410 per kilowatt, with an average system size of 7.5 kilowatts. The typical London homeowner spends $17,798 on their solar array after federal tax refunds. An estimate from a local provider will take into account additional information based on your desired system's size, capacity, required preliminary work, and panel type. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

There are a number of benefits to home solar energy. You can raise your property values, save money, and qualify for tax benefits. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.
It depends on your home's location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in London, your best time to get solar is in the spring and fall.
Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, so you can reap the environmental benefits and savings of solar energy without having to completely switch over.
Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can send the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.
While solar energy might not be the best option for some in dark or wet areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.
Yes, solar panels can still provide you with 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.
