Factors that Affect Solar Panel Costs in Wentzville

Though the average cost of a solar system in Wentzville is $13,108, your final cost may differ. There are several factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $2,590 per kilowatt in Wentzville. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Wentzville, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Wentzville to be too costly, even if the investment pays off over time. Thankfully, nearly every solar installer in the area provides financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in paying more over time because of interest. However, the interest on solar loans also increases your all-in costs, so it's important to consider that as well. You can always lower the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The solar company you pick will affect your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Wentzville know more about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you select the right company for you, here are some tips to keep in mind:

  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the completion timeline.
  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and efficiency. They will come at different price points as well. The company you choose affects which solar panel brands you have access to.
  • Contract: Before signing a contract with a solar company, make sure you look it over completely so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Reputation: Solar installers that have great reviews from their customers and that have been operating for many years most likely offer high-quality solar panel installation and expertise.
