Benefits of Solar Energy

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

  • Better energy independence: Photovoltaic solar panel systems with energy storage systems function through power outages and emergencies, and you won't have to rely on the grid for your safety and well-being.
  • Reduced energy costs: Generating some or all of your own electricity will cut power costs long-term. Plus, some states offer net metering programs that make it possible for you to sell your extra energy back to the grid, generating additional credits toward your energy bill.
  • Reduced carbon footprint: The sun is a highly abundant clean energy source, meaning you can lower or beat your home's dependence on non-renewable sources.

How To Choose the Best Solar Company in Madison

Choosing a company is the first step toward an effective and valuable solar energy system. Consider all of these factors in your service provider search.

Licensing and Training

For solar thermal installations, Wisconsin requires a licensed HVAC contractor or plumber to serve 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. Solar installers can also earn accreditations from trade groups and standards organizations. The top ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Madison

Your photovoltaic panels' model will affect how much energy you can generate. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

You can also add electric vehicle (EV) chargers and battery backup systems. These will increase your total installation cost, but they can boost your solar system's efficiency. Not every solar contractor provides these extras, so look for a contractor that installs them if it's essential for you.

Most Madison homeowners select solar systems sized for five kilowatts (kW) of electrical capacity. These systems cost about $19,400 to install, considering both parts and installation. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,156
Solar Polycrystalline$902
Solar Battery$740
Solar Home EV Charger$2,775

Financing Solar Energy in Madison

Choosing the optimal financing plan will impact your overall solar system cost and expected savings. Common payment options include loans, cash payments, leases, and power purchase agreements. Most solar experts recommend paying cash or using a solar loan. Cash payments require a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Similar to an auto or home loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to use your panels for a fixed monthly rate, while PPAs let you pay just for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We recommend working with an installer that offers multiple financing options. Speak with each agent about what's available, and secure more than one estimate for the best odds of staying within your spending limits.

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

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

1 kW2.0 years
2 kW4.0 years
5 kW10.0 years
10 kW20.0 years

Frequently Asked Questions About Solar in Madison

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

Most Madison homeowners spend about $1,384 on energy each year. Your costs could drop by $1,140.28 for each kilowatt you generate after you pay off a solar array.

How popular is solar energy in Madison?

Yes, solar energy is readily available in Madison. A growing number of local homes are already using solar power on-site or through utility grids, and Wisconsin has about 2871 jobs comprising its solar economy.

Should I anticipate a boost in my property value after going solar?

Yes, a solar PV system will raise your property value. According to the National Renewable Energy Laboratory, for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How many years does an average solar system last?

Today's solar systems are remarkably durable, lasting up to 25 years. Monocrystalline panels and other premium models tend to work longer than less expensive models.

How do I care for my new solar system?

To preserve your solar system's performance, inspections and cleanings every six months are usually sufficient. In dry or dusty seasons, your panels might need cleanings every one to two months. Your contractor can recommend a maintenance schedule. Its team could also tackle 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 larger system if your energy needs are more demanding. Solar contractors will evaluate your property's energy consumption and roof shading to suggest the appropriate system for you.

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

Most utilities and states run net metering programs, and some mandate homeowners to join. Once you enroll, you can receive a bill credit or check for any surplus electricity you generate and send to the grid. Generally, power companies compensate solar homeowners at a wholesale or "avoided-cost" rate.

Should I get quotes from multiple Madison solar companies?

Yes, we recommend obtaining free solar quotes from three or more companies. You should thoroughly read each quote and compare financing options, warranty details, prework scope and costs, labor fees and equipment costs. Ensure each quote presents an itemized financial plan and includes your anticipated payback period.
