Factors that Affect Solar Panel Costs in St Charles

Cost is often one of the most important factors for homeowners who want to invest in solar. There are a few major factors that determine your overall cost in St Charles: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend around $2,730 per kilowatt in St Charles. The type of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you choose 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 energy bills. Additionally, add-on products, like solar batteries, can bump up your total well above the St Charles average.

Solar Financing Terms

Most solar companies in St Charles have solar loans, which reduce the initial cost of installing a solar system. You'll have to consider the long-term cost of financing options, including the total 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 remarkably.

Solar Panel Installation Company

Lastly, the company you get to install your solar panel system can play a role in determining your pricing. St Charles' solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Reputation: Make sure your solar company has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like EcoWatch.
  • Solar Panel Brands: Different companies will carry various brands and types of panels. If you prefer a specific brand, make sure the solar installer you're considering has it.

EcoWatch's St Charles, IL Solar Cost FAQs

How much does it cost to install solar panels in St Charles?

This is a hard question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or more efficient panels, or if you have above-average energy usage. On the flip side, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Is it better to lease or buy solar panels in St Charles?

Leasing solar panels can be an appealing choice, as it commonly 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.

How will installing solar panels impact my home value?

Installing solar panels on your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in St Charles is currently $260,842, so you can expect about a value of about $10,695 more than houses without a solar system. The specific figures will vary, but most experts agree that installing solar panels in St Charles is a fruitful investment.

How many solar panels should I get to power my home?

To figure out what solar panel system size you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
