Factors that Affect Solar Panel Costs in Affton

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that will push your cost above or below the average in Affton: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,370.Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Affton, where sunlight is relatively abundant, efficiency can quickly pay off. Also, 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 Affton to be too expensive, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in paying more over time because of interest.Though solar loans make going solar more accessible for Affton homeowners, they can also raise the total you pay for your system due to interest. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

Finally, the company you get to install your solar panel system can play a role in determining your pricing. Affton’s solar companies all have different labor costs and add varying upcharges to equipment. Companies that 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 come with an above-average cost. It’s best to do some research and decide on the company that has the products, warranties and services you’re looking for and also fits within your budget.

How to Save on Solar Panels

Since the kind of solar panels and the installer you choose greatly influences your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and energy efficiency. They will come at different costs as well. The company you choose affects which solar panel brands you have access to.
  • Contract: Before you sign a contract with a solar company, make sure to look it over carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Warranty: If you’re worried about the durability of your solar panel system, ensuring your installer offers a 25-year, all-inclusive warranty can help put you at ease.
  • Installation Process: Get details from your solar company about the installation process and what to expect, including when the site survey will be done and how long it will take.
