Factors that Affect Solar Panel Costs in Alton

The cost of installing a solar system in Alton can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater 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 $3,760.The type of solar equipment you choose can bring your price up or down 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. On the other hand, more efficient panels could save you more over time on your power bills. Additionally, add-on products, like solar batteries, can bump up your total well above the Alton average.

Solar Financing Terms

Many homeowners find the average cost of solar in Alton to be too steep, even if the investment pays off over time. Fortunately, nearly every solar installer in the area provides access to financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also lead to higher prices over time due to interest.Though solar loans make adopting solar energy more accessible for Alton homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The last key cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Alton, you’ll have lots of options to choose from, but each comes at different price points for labor and equipment.Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It’s best to do some research and find a company that offers the products, warranties and services you’re looking for and also fits within your budget.

EcoWatch's Alton, IL Solar Cost FAQs

How much does it cost to install solar panels in Alton?

The average cost of solar panels in Alton is about $18,800 for a 5-kW system and $37,600 for a 10-kW system before the ITC, but the real cost will depend on stuff such as the kind of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in Alton?

Leasing solar panels can be an option if you can’t afford to pay upfront or secure 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 financial benefits from going solar.

Do solar panels increase your property value?

Solar panels can increase your home value significantly as long as you buy or finance your panels and don’t go for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% with a solar installation."

How long do solar panels last in Alton?

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 choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
