Benefits of Solar Energy

Solar energy offers multiple advantages. Let's look at a few of them.

  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can minimize or conquer your home's dependence on "traditional" sources.
  • Better energy independence: Solar systems with battery backups work through blackouts and emergencies, and you won't have to rely on the electrical grid for your safety and comfort.
  • Lowered energy bills: You can dodge the premium cost of grid-tied power by creating some electricity right where you use it.

What Solar Incentives Are Available to Peoria Homeowners?

Illinois homeowners who upgrade to solar could qualify for tax credits, reimbursements, special financing and rebates. Here are just a few of the local incentive programs.

How To Choose the Best Solar Company in Peoria

The cost and efficiency of solar panels often hinge on the solar company that installed them. Here are some important factors to bear in mind while searching for a solar specialist.

Licensing and Training

In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including home solar installers. 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 Peoria

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. 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 need to charge an electric car or use your solar power in inclement weather, you can pay extra for accessories. By choosing the right components, you can make your system more efficient and convenient to use. Not all solar contractors provide these optional components, so look for a contractor that sells them if it's essential for you.

Generally speaking, it costs about $18,800 for a five-kilowatt solar array in Peoria. This table displays more specific pricing information for different solar panel types and system components in your area.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,165
Solar Polycrystalline $909
Thin-Film $531
Solar Battery $746
Solar Home EV Charger $2,796

Financing Solar Energy in Peoria

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 cash payments, power purchase agreements (PPAs), solar leases and solar loans. We suggest making a cash payment 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 reduce 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 monthly installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate based only on the energy you use, similar to an electric bill. We usually don’t recommend these two choices because you won't own the system and are disqualified from using solar incentives. Look for providers that offer two or more payment plans to find the right fit for your pocket.

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

A 26% federal tax credit applies to new residential solar equipment purchased through 2032. Further incentives may be available through local governments, usually in the form of rebates and special financing programs.

Solar System Capacity Estimated Payback period
1 kW 2.8 years
2 kW 5.5 years
5 kW 13.8 years
10 kW 27.6 years

Frequently Asked Questions About Solar in Peoria

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

On average, Peoria homeowners spend approximately $851 per year for energy. Once you pay off your solar array, you could save $621.41 for every kilowatt you produce.

Is solar energy widely available in Peoria?

Yes, solar energy is readily available in Peoria. A growing number of local homes are already using solar power on-site or through utility grids, and Illinois has about 5513 jobs making up its solar economy.

Should I anticipate a property value increase after going solar?

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

What if I live in a dark or rainy

Even if your property has high tree cover, you could still benefit from solar energy. Your contractor will enhance your system's performance by choosing the proper site for panels, installing a battery backup system, positioning them to capture the most sunlight throughout the year, and cleaning them regularly. This way, you can keep solar energy longer and use it as necessary.

How can I assess my site's solar feasibility?

One common way to determine your home's solar viability is by using PVWatts. This powerful free tool considers system size, tree cover, local weather and topography, and panel efficiency to determine how much power your array could generate. However, it's not a substitute for consulting with a solar expert, who can build a full estimate with the most updated data.

What's the average solar system size in Peoria?

The average Peoria solar system size is 6.4 kilowatts (kW). However, your final system size depends on your family's energy needs. Your surrounding shading, panel model, and roof size could also impact your final result. A professional solar installer will consider these factors and determine the right array size for your home.

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

It's wise to gather at least three different estimates before committing to a single solar provider. This lets you evaluate warranty options, product quality, customer feedback, and pricing. It also lets you assess a company's responsiveness, reliability and knowledge, all of which are "green flags".
