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.
