Factors that Affect Solar Panel Costs in Mokena
Though the average cost of a solar system in Mokena is $16,997, your final cost may be higher or lower than that. There are many factors that can have a major impact on the cost of a solar panel installation. Below are some of the more important things to consider.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it’s a priority to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.The 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, more efficient panels could save you more over time on your electric bills. In addition, add-on products, like solar batteries, can bump up your total well above the Mokena average.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are available from most installers in Mokena, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable.You’ll have to consider the long-term cost of loans, including the total interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The solar panel installer you select will play a role in your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

EcoWatch's Mokena, IL Solar Cost FAQs
What is the average cost of installing solar panels in Mokena?
The average cost of solar panels in Mokena 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 like the model of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Mokena?
Leasing solar panels can be an option if you can’t afford to pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of 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 savings from going solar.
How much can I save on energy bills after switching to solar?
It is possible to erase your electricity bills with solar panels, but for most homeowners throughout Mokena, 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 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 should be disposed of at that time. What this means is their energy production will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
