Factors that Affect Solar Panel Costs in Des Plaines
The cost of installing a solar system in Des Plaines can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is the size of the system you need, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to pay about $3,760 per kilowatt in Des Plaines.The solar equipment you choose can bring your price up or down 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. On the other hand, more efficient panels could save you more in the long run on your energy bills. Additionally, extra products, such as solar batteries, can bring your total well above the Des Plaines average.
Solar Financing Terms
Solar panels can save you money on energy bills over time, but they can also be a big investment. That’s why many Des Plaines homeowners choose to finance their solar panel systems to make going solar more affordable.Though solar loans make going solar more accessible for Des Plaines homeowners, they can also increase the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar company you pick will influence your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.You may notice national solar installers that have lower prices due to their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels
The solar company you choose will affect not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should take into account, including:
- Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should secure and how long the project will take.
- Reputation: Your solar installer should have a sound reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from previous customers.
- Solar Panel Brands: The type of solar panel you’d like plays a role in which installer you should go with, since different companies have different panels.
- Contract: It’s important to read your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what you can expect about the installation process.

EcoWatch's Des Plaines, IL Solar Cost FAQs
How much does it cost to install solar panels in Des Plaines?
The average cost of solar panels in Des Plaines 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 certain factors such as 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 Des Plaines?
Leasing solar panels can be an attractive choice, as it typically 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 option if you want to get the most savings.
Is it worth going solar in Des Plaines?
Solar panels can be a great investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already reasonably low, solar panels might not be for you.
How many solar panels should I get to power my home?
To figure out how many solar panels you need, you need to know 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 home will need 20 to 35 panels.
