Factors that Affect Solar Panel Costs in Summit
For many Summit homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Summit, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $3,760. The brand and type of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
If paying for solar panels out of pocket is difficult, solar loans are an affordable route because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also increases your total costs, so it’s crucial to take that into consideration as well. You can always lower the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installer you choose will impact your total cost to go solar. Different companies will charge different amounts for the equipment and labor.Additionally, some companies in Summit know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
The solar company you go with will impact 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 some important things you should consider, including:
- Warranty: Warranties that cover panel repairs and maintenance over around 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a quality company.
- Installation Process: When making the switch to solar power, it’s important to keep an open line of communication with your solar panel installer. See to it that you understand how the installation process works and the project timeline.
- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. Two 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 positive reviews from past customers.
- Contract: Even though reading through a contract can be tedious, it’s important to do it carefully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
EcoWatch's Summit, IL Solar Cost FAQs
How much does it cost to install solar panels in Summit?
This is a hard question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $18,800 for a 5-kW system and $37,600 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you want a smaller solar panel system or cheaper solar panels.
Is cost the most important thing to keep in mind when buying solar panels?
Cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to think about are the quality and durability of your solar panels.
Is switching to solar power worth it?
Solar panels can be a fruitful investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already reasonably low, solar panels might not be for you.
How often do you have to replace solar panels?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
