Factors that Affect Solar Panel Costs in Affton
Cost is usually one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that affect your total cost in Affton: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,590. The kind of solar panels and equipment you want is another factor that will substantially impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment consists of more than just the solar panels themselves. You'll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that's in your budget.
Solar Financing Terms
Solar panels can save you money on power bills over time, but they can also be a significant investment. That's why many Affton homeowners decide to finance their solar panel systems to make going solar more affordable. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar panel installation company you select will affect your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor. Some companies only sell high-efficiency and high-priced 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 go with the company that offers 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 choosing a company can be a challenge, we have some tips to help you, such as:
- Solar Panel Brands: Different companies offer different brands and models of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
- Contract: It's important to look over your solar installer's contract thoroughly to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
- Installation Process: Homeowners should make sure they understand how exactly the installation process will go, as well as important factors like the project timeline.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can check your installer's reputation is by reading reviews.

EcoWatch's Affton, MO Solar Cost FAQs
How much does it cost to install solar panels in Affton?
The average cost of solar panels in Affton is about $12,950 for a 5-kW system and $25,900 for a 10-kW system before the ITC, but the real cost will depend on stuff like the model of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Affton?
Leasing solar panels can be an option if you can't afford to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your property value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.
Does Affton have a net metering program?
Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just give you credit toward your future power bills.
How often do you have to replace solar panels?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
