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 lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.
Confirm that your solar installer is properly licensed. This helps ensure that the work is done properly using current installation best practices. For solar thermal installations, Wisconsin requires a licensed HVAC contractor or plumber to be a part of the team if the work involves heating equipment or potable water. There are fewer restrictions for solar photovoltaic systems, but either the Wisconsin Division of Safety and Buildings or your city government may have to review building plans before you begin.
Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.
Get free, detailed quotes from at least three solar companies. The quotes should list all costs and identify the solar parts included. Looking at several quotes can help you find the option that best fits your budget.
Quality solar installations should come with strong workmanship and performance guarantees. A workmanship warranty addresses any installation defects (such as poor alignment, cracks in the panels, or poor wiring), while a performance guarantee ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.
Solar energy is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
In Janesville, solar panels cost an average of $3,880 per kilowatt, with an average system size of 7.2 kilowatts. The typical Janesville homeowner spends $19,674 on their solar array after federal tax refunds. An estimate from a local provider will consider additional information reflecting your desired system's panel type, size, required preliminary work, and capacity. In some cases, homeowners may prefer to lease solar panels to reduce upfront costs.
Incentive Type: Property Tax Incentive
Incentive Amount:
100% of the value added by an eligible renewable energy system
Generally speaking, a solar photovoltaic (PV) array can be used to power any household appliance or system that uses electricity. In the smallest case, you can use a solar water heating system.
With home solar panels, you can save money on your energy bill, lower your home's carbon footprint, and gain additional energy independence.
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 Janesville, your best time to get solar is in the spring and fall.
Yes, you can use home solar energy alongside conventional power sources. In most parts of the country, 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.
Yes, solar panels will still be able to generate energy during a grid outage. To ensure that your solar system can keep working during a power outage, make sure to choose a quality solar provider that offers battery backup systems or emergency generators.
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. Regarding insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should talk with your accountant or insurance agent for information specific to your case.
