How To Choose the Best Solar Company in St. Charles

Choosing a company is the first step toward an effective and valuable solar energy system. Consider each of these elements in your company search.

Licensing and Training

In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including residential solar contractors. Check a company's website for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among 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 St. Charles

The style of solar panels you purchase determines how much energy you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

If you need to charge an electric car or use your solar power in dark weather, you can pay extra for accessories. By choosing the right components, you can make your panel array more efficient and convenient to use. Not every solar contractor offers these additional features, so look for a provider that installs them if it's a priority for you.

You can expect to pay about $18,800 on average for a five-kilowatt solar energy system in St. Charles. Check the table in this section to get an idea of the amount St. Charles solar companies might quote for your specific system.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,154
Solar Polycrystalline $900
Thin-Film $526
Solar Battery $739
Solar Home EV Charger $2,769

Financing Solar Energy in St. Charles

There are various ways to pay for new solar panels, and the right one will reduce your expenses. A few of the most common options include leases, power purchase agreements (PPAs), cash payments, and loans. Most solar experts recommend paying cash or using a solar loan. Cash payments demand a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Similar to a home or auto loan, you'll pay a set monthly rate with as little as $0 down. 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, like an electric bill. We usually don’t recommend these two options because you won't own the system and cannot use solar incentives. Look for installers that offer several payment plans to find the right fit for your budget.

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

A 26% federal tax credit applies to new residential solar equipment purchased through 2032. Additional 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 St. Charles

How much money could I save by going solar in St. Charles?

On average, St. Charles homeowners spend around $1,156 per year on energy bills. Once you repay your solar array, you could save $784.48 for every kilowatt you produce.

How popular is solar energy in St. Charles?

Yes, solar energy is becoming increasingly popular in St. Charles. Some homes already benefit from solar power on-site or through utility grids, and they're fortified by a state solar economy with 5513 jobs and counting.

Will solar energy systems improve my St. Charles home value?

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 boost your property value by $12,000.

How long is a St. Charles solar panel's average lifespan?

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

How long does the photovoltaic installation process take?

There's no universal answer for how long a solar project might take. Ultimately, it depends on system size, local weather, the permitting and inspection process, panel style, and the necessary prework. Many homeowners can be solar-ready within a few months from their initial estimate visit.

What upkeep do my solar panels need, and how frequently do they need it?

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

What are some "red flags" to watch for as I research companies?

Even the most esteemed St. Charles solar installers will have both supportive and negative reviews. To make the most informed decision possible, focus on these warning signs to know if a company isn't worth your investment:
  • High-pressure sales tactics
  • Being evasive about training and credentials, warranties, cost and references
  • Inflexible options
  • Superficial, rushed site evaluation
  • More mixed or negative reviews than positive ones

How are a solar lease and PPA different?

After you sign a power purchase agreement, your solar contractor will not charge to install or maintain your new panel array. Instead, you'll pay them only for the electricity you generate. Typically, PPAs last for 10–25 years or until you "buy out" of the contract.

If you choose a lease, you'll make set monthly payments.

With both leases and PPAs, you don't own your panels and lose eligibility for some incentives. Further, you'll have to "buy out" or transfer the contract if you sell your home during the term.
