Factors that Affect Solar Panel Costs in Mascoutah

Though the average cost of a solar system in Mascoutah is $16,000, your actual cost may differ. There are quite a few factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production require 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.There are many different solar panel brands and the one you pick also affects the cost. Usually, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you’re looking to get can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in Mascoutah to be prohibitively costly, even if the investment pays off over time. Thankfully, almost every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to a higher cost over time due to interest.However, the interest on solar loans also increases your total costs, so it’s important to consider that as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Lastly, the company you get to install your solar panels can play a role in determining how much it costs. Mascoutah’s solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell high-quality, high-efficiency and high-price 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 decide on the company that has the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

There are numerous companies to choose from in Mascoutah, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:

  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you opt for.
  • Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years most likely offer high-quality solar panel installation and expertise.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to align on any details you need to know with your solar installer, such as what permits you should acquire and how long the project will take.
  • Contract: It’s important to look over your solar installer’s contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.

EcoWatch's Mascoutah, IL Solar Cost FAQs

What is the average cost of installing solar panels in Mascoutah?

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

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

Leasing solar panels can be an option if you can’t 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.

Does Mascoutah have a net metering program?

The majority of states have net metering programs of some kind. Through these, you can get paid for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy needs and the amount of sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to get between 20 and 35 panels to account for their typical energy usage.
