Factors that Affect Solar Panel Costs in Willowbrook

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Willowbrook: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher 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 $2,730. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Willowbrook, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are offered by most installers in Willowbrook, which can reduce, or in some cases totally eliminate, your upfront costs to make solar more affordable. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

Lastly, the company you get to install your solar system can play a role in determining how much it costs. Willowbrook's solar companies all have different labor costs and add varying upcharges to equipment. You may see national solar installers that have lower prices due to their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

The solar panel company you go with will affect not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should keep in mind, including:

  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.
  • Contract: It's important to look over your solar installer's contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the best you can get in the business, and offering that kind of warranty is one mark of a good company.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like EcoWatch.

EcoWatch's Willowbrook, IL Solar Cost FAQs

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

This is a tough question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Willowbrook?

Leasing solar panels can be an option if you can't pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home 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.

Can you sell solar power back to the grid in Willowbrook?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future utility bills.

How many solar panels should I get to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
