Factors that Affect Solar Panel Costs in St. Charles
There are many criteria that can influence your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
The size of the solar system you need to offset your energy usage, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $4,030. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like St. Charles, where sunlight isn’t as abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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
For some homeowners, paying for a solar system out of pocket can be challenging. Solar loans are provided by most installers in St. Charles, which can lower, or in some cases eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also increases your all-in costs, so it’s vital to keep that in mind as well. You can always reduce the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
The solar installer you choose will influence your total cost to make the switch to solar energy. Different companies will charge different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and go with the company that offers the products, warranties and services you’re looking for and also is within your budget.
