Benefits of Solar Energy

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

  • Reduced carbon footprint: Adopting solar is a surefire way to reduce your carbon footprint and home fossil fuel dependency.
  • Better energy independence: Adding a solar battery storage system lets you have reliable energy during storms and grid outages.

How To Choose the Best Solar Company in Wentzville

The price and efficacy of solar panels often hinge on the solar company that installed them. Make your choice based on the following crucial aspects.

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. Solar companies can also obtain accreditations from standards organizations and trade groups. The most respected ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Wentzville

The kind of solar panels you purchase determines how much electricity you can produce. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

Additional accessories, such as battery storage and electric vehicle (EV) chargers, will increase your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar provider includes these extras, so look for a company that installs them if it's important for you.

Generally speaking, it will cost about $16,850 for a five-kilowatt solar array in Wentzville. This table shows more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,118
Solar Polycrystalline$872
Thin-Film$510
Solar Battery$715
Solar Home EV Charger$2,683

Financing Solar Energy in Wentzville

There are numerous ways to pay for a solar energy system, and the right one will help you decrease overhead. A few of the most common options include cash payments, loans, leases, and power purchase agreements (PPAs). Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid 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 a home or auto loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to rent your panels for a set 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 do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each company you're evaluating about the financing options it offers. A salesperson can help you determine the best option for your pocketbook.

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

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

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

Most Wentzville homeowners spend about $1,291 on energy each year. Your costs could drop by $809.62 for each kilowatt you generate after you pay off a solar array.

Is solar energy widely available in Wentzville?

Yes, solar energy is on the rise in Wentzville. Some homes already use solar power on-site or through utility grids, and they're supported by a state solar economy with 2647 workers and counting.

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

What if I live in a heavily-wooded or dark

A solar system could still work well in cloudy conditions. Your contractor will orient your panels to capture the most sunlight possible. They might also recommend a back-up power source to keep your system working at its best.

How can I assess my site's solar feasibility?

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

How do I care for my new solar system?

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

How can I enhance my solar panels' performance?

To enhance your solar system's performance, you can use the following strategies:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

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

Net metering is a system that credits solar homeowners for any excess electricity they generate and feed back to the grid.

Some states or power companies oblige you to enroll in net metering when purchasing your solar system, while others give you a choice. Either way, once you participate, you'll get a bill credit or check for your excess generation at a wholesale or retail rate.
