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 key factors that determine your overall cost 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

When it comes to estimating the price of solar panels in Affton, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy consumption, which you can gauge by looking at past electricity bills. Your total cost can increase by about $2,590 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Affton, 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 a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on utility bills over many years, but they can also be a significant investment. That's why many Affton homeowners opt to finance their solar panel systems to offset upfront costs. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

The solar company you choose will impact your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor. The size of the company sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because they have access to greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Installation Process: Get details from your solar installer about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been in business for many years most likely offer good-quality solar panel installation and expertise.
  • Contract: When reading through your solar installer's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios like a system part breaking or the company going out of business.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.

EcoWatch's Affton, MO Solar Cost FAQs

What is the average cost of installing 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 actual cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Affton?

Leasing solar panels can be an appealing choice, because it usually comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Can you sell solar power back to the grid in Affton?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future electricity bills.

How often do you have to replace solar panels?

Even though 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 their energy production will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency.
