How To Choose the Best Solar Company in O'Fallon

Choosing a company is the first step toward an effective and cost-efficient solar system. Make your choice based on the following essential elements.

Licensing and Training

In Missouri, it's the responsibility of counties and cities issue contracting licenses. However, all contractors must register with the Missouri Secretary of State. You should also visit a company's website to learn about its private certifications. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in O'Fallon

The kind of solar panels you choose decides how much electricity you can generate. Monocrystalline panels cost more but give you the best performance. 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.

Additional system add-ons, 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 provider offers these extras, so look for a provider that installs them if it's crucial for you.

You can plan to spend about $16,850 on average for a five-kilowatt solar energy system in O'Fallon. Use the table in this section to get an idea of what amount O'Fallon solar companies might quote for your specific system.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,141
Solar Polycrystalline $890
Thin-Film $520
Solar Battery $731
Solar Home EV Charger $2,739

Financing Solar Energy in O'Fallon

Choosing the ideal financing plan will influence your overall solar system cost and potential savings. Common payment options include loans, power purchase agreements, cash payments, and leases. Though it involves a large up-front payment, cash is the most economical choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best 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 rent your panels for a fixed monthly rate, while PPAs let you pay just for the energy you use, akin to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We advise working with a provider that offers multiple financing options. Speak with each agent about what's available, and obtain more than one estimate for the best odds of staying within your financial plan.

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

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.

Frequently Asked Questions About Solar in O'Fallon

How much money could I save by going solar in O'Fallon?

On average, O'Fallon homeowners shell out roughly $1,291 per year on energy bills. Once you repay your solar array, you could reduce your costs by $809.62 per kilowatt you produce.

Is solar energy readily available in O'Fallon?

Yes, solar energy is gaining popularity in O'Fallon. Some homes already benefit from solar power on-site or through utility grids, and they're fortified by a state solar economy with 2647 workers and counting.

Should I expect a property value increase after switching to solar energy?

Yes, a solar PV system will raise your property value. According to the National Renewable Energy Laboratory (NREL), 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 rainy or dark

Solar panels could still work well in cloudy conditions. Your installer will position your panels to absorb the most sunlight possible. They might also recommend a back-up power source to keep your system functioning at its best.

How do I care for my new solar system?

Solar panels don't require much upkeep to keep working well. All you'll need to do is clean and inspect the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to help you in your system's care.

What's the average solar system size in O'Fallon?

A typical O'Fallon solar home uses a 7.2-kW panel array, but you might need a bigger system if your energy needs are more demanding. Solar professionals will evaluate your property's power usage and roof shading to recommend the appropriate system for you.

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

Even the most renowned O'Fallon solar providers will have both glowing 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
  • Not being straightforward about references, warranties, training and credentials and cost
  • Inflexible options
  • Rushing through the site assessment
  • More mixed or negative reviews than positive ones

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

A power purchase agreement is a contract between you and your installer. They install, own, and maintain the panels, and you purchase the generated electricity from them for 10–25 years. There will usually be options to extend the agreement and buy out early to own your system.

In contrast, solar loans can come from specialty lenders, installer, the government and local banks. You'll need to pass a credit check to qualify for most of them. While the upfront costs are more expensive, and you'll be responsible for maintenance, you'll also have total ownership and can apply for many more benefits.
