How To Choose a Solar Company

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 researching local solar installers are as follows.

Check Licensing

Hiring a licensed solar installer is critical. 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 the crew 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.

Read Customer Reviews

Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers are saying about local solar providers. Reviews can give you an idea of a company’s dependability and customer service. Avoid companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

To find a solar installer that works with your budget, get free, detailed quotes from at least three providers. The quotes should outline all costs and list the solar equipment included. Comparing several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

High-quality solar installations should come with robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like poor wiring, cracks in the panels, or poor alignment. The output warranty ensures an energy generation baseline. Strong guarantees reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Solar energy can help lower your electricity costs long-term. When considering solar panel's cost and value, be sure to consider these considerations.

  • Compare system purchase options: Solar panels can be purchased upfront or financed over time with loans or leases. Confirm key financing details like payment schedule, fees, annual percentage rate (APR), and ownership implications when financing solar panels.
  • Look into utility rebates: Local electric providers may offer additional rebates to encourage homeowners to switch to solar power. Check the requirements to qualify and the rebate values with your local power company to determine what your savings could be.
  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states offer incentives, too. The credits can lead to substantial savings for solar buyers.

Beloit homeowners typically spend about $19,674 on home solar systems after federal tax refunds.

There are many benefits to home solar energy. You can raise your property values, qualify for tax benefits, and reduce emissions. 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 location and what type of panels you're installing. Since there's a moderate amount of snowfall in Beloit, your best time to get solar 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.

The average annual savings in Beloit amount to $1,424.

Your payback period is the time to earn a net profit from your solar panels. It will vary based on the rate your utility charges per kilowatt of power, the average sunlight in your area, and their rated capacity. Beloit gets a moderate amount of sunlight each day, so you could expect a maximum payback period of 13.8 years per 5 kW of power depending on other factors.

The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should clean your panels regularly and inspect them for damage. Many solar contractors in the Beloit area offer comprehensive maintenance plans to help you make the most of your panels and keep them healthy for as long as possible.

Some frequently-used types of home solar panels in Beloit include polycrystalline, thin-film and monocrystalline.

Talk with your local provider about what kinds of solar panels they work with.
