Factors that Affect Solar Panel Costs in Webster Groves

For many Webster Groves homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Webster Groves, with typical prices between $20,000 to $40,000. There are a number of factors that greatly influence the price you'll pay, which we'll go over below.

Solar Equipment

The size of the solar energy system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $2,590. The kind of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more over time on your electric bills. In addition, add-on products, such as solar batteries, can bring your total well above the Webster Groves average.

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 Webster Groves homeowners opt to finance their solar panel systems to make going solar more affordable. You'll have to consider the long-term cost of loans, including the amount of interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

The final key cost factor you should consider is the installer you choose. Given the booming popularity of sustainable energy solutions in Webster Groves, you'll have lots of options to choose from, but each comes at different price points for labor and equipment. Additionally, some companies in Webster Groves are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
  • Warranty: A high-quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

EcoWatch's Webster Groves, MO Solar Cost FAQs

What is the average cost of installing solar panels in Webster Groves?

This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $12,950 for a 5-kW system and $25,900 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or more efficient panels, or if you have above-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Are solar panels free in Webster Groves?

You can't get solar panels for free in Webster Groves. However, you may still be able to afford them on a lower budget. You can lease solar panels for a low upfront cost or, if you want to own your solar panels, you can finance them with a solar loan.

Can solar panels completely eradicate my electricity bills?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners throughout Webster Groves, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you'll want to contact a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in Webster Groves?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency.
