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 researching local solar installers are as follows.
It's important to hire a licensed solar installer. This help guarantee that the work is done properly using the most up-to-date installation methods. Ohio may require a solar company to hold a state contractors' license, but only for commercial work. For residential work, cities can establish their own licensing or regulatory requirements.
Check review sites like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.
Call 3–5 solar companies for free, itemized quotes. A quote should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the best option that fits your budget.
High-quality solar installations should have robust workmanship and performance guarantees. The workmanship guarantee covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output warranty guarantees an energy generation baseline. Strong guarantees reflect a solar provider's confidence in its installations.
Solar energy can help lower your energy expenses. Be sure to weigh these aspects when determining the cost and value of solar panels.
The average Louisville homeowner will spend around $18,563 on a home solar system after federal tax refunds. Solar arrays in Louisville cost roughly $3,410 per kilowatt, with the average residential solar system being 7.8 kilowatts. A personalized estimate from a local solar provider will include costs for preliminary work, labor, and permit fees, and will account for your system's size, capacity, and panel type. Some homeowners prefer to lease solar panels to reduce upfront costs.
Incentive Type: PACE Financing
Incentive Amount:
Low-interest, 30-year loan
A solar photovoltaic (PV) system can generate power to run any electric system or appliance in your home. More specifically, you can install a solar heating system for your water.
With home solar panels, you can save money on your energy bill, lower your property's emissions, and be better prepared if there's an outage to the local grid.
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 Louisville, your best time to install solar panels is in the spring and fall.
Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Louisville amount to $1,091.
You might be pleasantly surprised at how quickly you can get a return on investment from your solar panels. In areas like Louisville with moderate sunlight, the period could last 17.0 years per 5 kW of power, but may be shorter if you have low electricity costs or a smaller energy capacity.
Regarding taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. As for insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should speak with your accountant or insurance agent for information specific to your case.
Solar panels are becoming more relevant than ever for their high efficiency and low maintenance costs. Depending on how much sunlight your property receives, you may find they're the best performing source of renewable energy compared to others.
