How To Choose the Best Solar Company in Madison

The more thorough your company research is, the better your solar installation will ultimately perform. Consider each of these factors in your contractor search.

Licensing and Training

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 PV systems, but either your city government or the Wisconsin Division of Safety and Buildings may have to review building plans before you begin. Check a company's website for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar sector's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Madison

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels provide a lower price point but produce less power. 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.

If you want to charge an electric vehicle (EV) or use your solar power in cloudy weather, you can pay extra for add-ons. By choosing the right components, you can make your panel array more efficient and convenient to use. Not every solar provider offers these optional components, so look for a provider that sells them if it's crucial for you.

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

Solar Panel Cost Average Cost
Solar Monocrystalline $1,156
Solar Polycrystalline $902
Thin-Film $527
Solar Battery $740
Solar Home EV Charger $2,775

Financing Solar Energy in Madison

There are many ways to pay for a new solar system, and the right one will minimize your overhead. A few of the most common options include loans, cash payments, power purchase agreements (PPAs), and leases. Though it requires a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the runner-up option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-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 PPA lets you pay a variable 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 suitable in specific circumstances. Ask each company you're vetting about the payment options it offers. A team member can help you determine the most suitable option for your pocketbook.

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

You can claim a 26% federal tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.

Solar System Capacity Estimated Payback period
1 kW 2.0 years
2 kW 4.0 years
5 kW 10.0 years
10 kW 20.0 years

Frequently Asked Questions About Solar in Madison

How much energy and money could I save per year by switching to solar?

On average, Madison homeowners spend approximately $1,384 per year on electric bills. Once you repay your solar array, you could reduce your costs by $1,140.28 for every kilowatt you produce.

Is solar energy readily available in Madison?

Yes, solar energy is gaining popularity in Madison. Some homes already benefit from solar power on-site or through utility grids, and they're backed by a state solar economy with 2871 job opportunities and counting.

Should I anticipate a property value increase after adopting solar power?

Yes, new solar systems translate 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 boost your property value by $12,000.

How many years will a standard solar system last?

Today's solar installations are remarkably durable, lasting up to 25 years. Monocrystalline options and other top-tier models tend to live longer than cheaper models.

How do I care for my new solar system?

To preserve your solar system's efficiency, inspections and cleanings every six months are usually enough. In dry or dusty seasons, your panels might need cleanings every few months. Your provider can recommend a maintenance schedule. Its team could also handle the cleaning for you.

What's the average solar system size in Madison?

A typical Madison solar home has a 7.3-kW panel array, but you might need a smaller system if your energy needs are higher. Solar installers will consider your property's energy consumption and roof shading to suggest the proper system for you.

What is "net metering," and how does it work?

Net metering is a method that credits solar homeowners for any excess electricity they generate and send back to the grid.

Some states or power companies oblige you to join net metering when installing your solar system, while others give you a choice. Either way, once you sign up, you'll receive a bill credit or check for your excess generation at a retail or wholesale rate.

How many estimates should I get before making a final solar company decision?

It's prudent to collect three or more estimates before committing to a single solar installer. This lets you evaluate pricing, customer feedback, warranty options, and product quality. It also helps you assess a contractor's responsiveness, knowledge and reliability, all of which are positive signs.
