Factors that Affect Solar Panel Costs in Alton

Although the average cost of solar panels in Alton is $12,364, your final cost may differ. There are many factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment Size

When it comes to estimating the cost of a solar system in Alton, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can figure out by looking at past power bills. Your overall cost can increase by around $2,730 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Alton, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Alton homeowners choose to finance their solar panel systems to make paying for solar more affordable. However, the interest on solar loans also adds to your all-in costs, so it's vital to consider that as well. You can always bring down the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

The solar installation company you select will influence your total cost to make the switch to solar energy. Different companies will bill different amounts for the equipment and labor. Some companies only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and choose a company that has the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, such as:

  • Contract: Read the contract terms thoroughly to make sure you understand the total cost, project timeline incentives and warranties.
  • Solar Panel Brands: Not all solar companies offer 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: An important thing to understand when going solar is the installation process itself. Be sure to clarify any details you need to know with your solar company, such as what permits you should acquire and how long the project will take.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely have a solid reputation and are qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
