Benefits of Solar Energy

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

  • Better energy independence: Solar systems with energy storage work through blackouts and emergencies, and you won't have to depend on the power grid for your safety and comfort.
  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, minimizing your regular electricity costs. You can eliminate your bills completely if you go off-grid.

How To Choose the Best Solar Company in Wauwatosa

Choosing a company is the first step toward an effective and cost-efficient solar array. Make your choice based on the following crucial aspects.

Licensing and Training

For solar thermal installations, Wisconsin requires a licensed plumber or HVAC contractor 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 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 reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Wauwatosa

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. 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 components, such as battery storage and electric vehicle (EV) chargers, will add to your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar contractor offers these add-ons, so look for a provider that sells them if it's crucial for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,187
Solar Polycrystalline$926
Solar Battery$760
Solar Home EV Charger$2,848

Financing Solar Energy in Wauwatosa

Choosing the optimal financing option will impact your overall solar system cost and potential savings. Common payment options include loans, leases, power purchase agreements, and cash payments. We advise paying with cash or using a solar loan for the best return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar incentives to cut your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) permits you to pay a monthly rate based only on the energy you use, like an electric bill. We usually don’t recommend these two choices because you won't own the solar system and cannot use solar incentives. Look for companies that offer two or more 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 Wauwatosa.

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

Frequently Asked Questions About Solar in Wauwatosa

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

Most Wauwatosa homeowners spend about $1,295 on energy each year. Your costs could drop by $1,187.58 for each kilowatt you generate after you pay off a solar array.

Is solar energy easily accessible in Wauwatosa?

Yes, solar energy is readily available in Wauwatosa. A growing number of area homes generate or access 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 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 increase your home's value by $12,000.

What is a Wauwatosa solar panel's average lifespan?

Modern solar installations are built for longevity. The average panel provides 25 years of reliable power. Lower-cost panels tend to last shorter than higher-quality models.

What's the average solar system size in Wauwatosa?

The average Wauwatosa solar system size is 6.9 kilowatts (kW). However, your final system size depends on your home's energy needs. 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 long does it take to pay back a solar loan in Wauwatosa?

Most Wauwatosa homeowners pay back a solar loan in 11.4 years. You can shorten the payback period by paying off extra loan principal each month.

What's the difference between a PPA and traditional financing?

The main differences between a PPA and traditional financing are that you pay a fluctuating monthly rate based on your energy usage and don't own your system. Your solar company installs and maintains the panels, and you pay for the generated electricity for 10–25 years. Afterward, you can extend the agreement or purchase the system outright.

You might look into a PPA if you don’t want to be responsible for maintaining your panels and don’t want to invest in a system, but keep in mind you won’t be paying toward ownership or be able to access any solar financial incentives. Many solar experts don’t recommend PPAs. Our guide covers other financing options above.
