Factors that Affect Solar Panel Costs in Naperville

The cost of installing a solar system in Naperville can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size. Solar power systems with better efficiency or power generation need 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 $2,730. There are several different solar panel brands and the one you pick also changes the cost. Usually, the brands that offer higher efficiency tend to also cost more. Plus, the type of equipment you choose can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system in cash is out of reach, solar loans are a popular route because they reduce your upfront costs and allow you to pay for your system over five to seven years on average. When estimating your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

Finally, the company you hire to install your solar panel system can affect the cost. Naperville's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Naperville have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you select the right company for you, here are some tips to keep in mind:

  • Contract: Although reading through a contract can be tedious, it's important to do it carefully so you can make sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Reputation: Make sure your solar installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like EcoWatch.
  • Solar Panel Brands: Different companies will offer different brands and kinds of panels. If you want a specific brand, make sure the solar company you're considering has it.
  • Warranty: Companies typically offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.

EcoWatch's Naperville, IL Solar Cost FAQs

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

The average cost of solar panels in Naperville is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on stuff like the model of solar panels you want, what size system you need and how much energy you consume.

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

Leasing solar panels can be an attractive choice, because it commonly comes with low or $0 upfront payments. The drawback 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 way to go if you want to get the most savings.

Is it worth going solar in Naperville?

Whether or not solar panels are worth it depends on some different factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy usage and the average daily sunlight your roof gets. You can 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 install between 20 and 35 panels to account for their typical energy usage.
