Benefits of Solar Energy

Solar energy offers several advantages that will enhance your home for years to come.

  • Lowered energy bills: With a solar array, you produce power without paying the tacked-on costs of grid-tied power. Going off-grid can eliminate your bills completely.
  • Reduced carbon footprint: Using clean solar power reduces your dependence on fossil fuels, which release greenhouse gases that damage the environment.
  • Better energy independence: Adding a solar battery lets you have reliable energy during storms and grid outages.

How To Choose the Best Solar Company in Janesville

The more thorough your provider search is, the better your solar panels will ultimately function. Consider all of these elements in your service provider search.

Licensing and Training

For solar thermal installations, Wisconsin requires a licensed plumber or HVAC contractor to be the team if the work involves heating equipment or potable water. There are fewer restrictions for solar PV systems, but either the Wisconsin Division of Safety and Buildings or your city government may have to review building plans before you begin. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Janesville

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as electric vehicle (EV) chargers and battery storage, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar company includes these additional features, so look for a contractor that sells them if it's essential for you.

If you're a resident of Janesville and are looking into a five-kilowatt solar energy system, you could plan to spend about $19,400 for parts and installation. See more information on specific component and panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,104
Solar Polycrystalline$861
Solar Battery$707
Solar Home EV Charger$2,649

Financing Solar Energy in Janesville

Solar installers offer multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar leases, solar loans, cash payments and power purchase agreements (PPAs). Though it requires a large up-front payment, cash is the most cost-effective choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the second most effective option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a power purchase agreement lets you pay a fluctuating rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in certain circumstances. Look for providers that offer several payment plans to find the right fit for your financial needs.

The table below lists the average payback periods for different capacities of solar systems in Janesville.

The IRS allows you to claim a 26% federal tax credit on total system costs, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own financing programs, incentives, and rebates that could save you more money.

Frequently Asked Questions About Solar in Janesville

How much money could I save by going solar in Janesville?

On average, Janesville homeowners shell out roughly $1,183 per year on energy bills. Once you repay your solar array, you could save $1,011.47 per kilowatt you produce.

Is solar energy easily accessible in Janesville?

Yes, solar energy is readily available in Janesville. A growing number of area homes generate or access solar power on-site or through utility grids, and Wisconsin has about 2871 jobs making up its solar economy.

Should I expect a boost in my property value after installing solar panels?

Yes, new solar systems lead to higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could increase your home's value by $12,000.

How long will an average solar system last?

Today's solar systems are impressively durable, lasting up to 25 years. Monocrystalline options and other top-tier models tend to live longer than "budget-friendly" models.

How do I care for my new solar system?

Solar panels don't demand much upkeep to keep working for your home. All you'll need to do is inspect and clean the panels every six months or as necessary in dusty seasons. Solar providers frequently offer maintenance packages to help you in your system's care.

What size should my new Janesville solar system be?

The average Janesville solar system size is 7.2 kilowatts (kW). However, your final system size depends on your family's electricity usage. Your surrounding shading, roof size, and panel model could also impact your final result. A professional solar contractor will consider these factors and determine the right system size for your home.

How can I boost my solar panels' performance?

To enhance your solar system's performance, you can use the following steps:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

How are a solar lease and PPA different?

Choosing a leasing option means your solar provider will handle panel maintenance while you make fixed monthly payments. PPAs differ slightly because you pay for just the electricity you produce.

You don't own the panels with either option, though you can choose to opt out of the contract for a fee.
