Factors that Affect Solar Panel Costs in Alton
There are several criteria that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. That’s why it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Alton, 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
Many homeowners find the average cost of solar in Alton to be too costly, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to higher prices over time because of interest.However, the interest on solar loans also increases your all-in costs, so it’s important to take that into consideration as well. You can always reduce 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 adopt solar energy. Different companies will bill different amounts for the equipment and labor.The company’s size sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger names.

There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you pick the right company for you, here are some tips to keep in mind:
- Warranty: If you’re concerned about the durability of your solar panel system, making sure your installer offers a 25-year, all-inclusive warranty can help put you at ease.
- Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you hire.
- Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be completed and what the project timeline is.
- Contract: Though reading through a contract can take a lot of time, it’s important to do it thoroughly so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
