Factors that Affect Solar Panel Costs in Oak Brook

The cost of installing a solar system in Oak Brook can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.

Solar Equipment

The size of the solar system you need to offset your energy usage, 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 $2,730. 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, higher efficiency could save you more over time on your electric bills. Additionally, add-on products, like solar batteries, can bump up your total well above the Oak Brook average.

Solar Financing Terms

Solar panels can save you money on utility bills over many years, but they can also be a big investment. That's why many Oak Brook homeowners choose to finance their solar panel systems to offset upfront costs. Although solar loans make going solar more accessible for Oak Brook homeowners, they can also raise the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

Lastly, the company you hire to install your solar panel system can affect your pricing. Oak Brook's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically 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 additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a lot of 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:

  • Installation Process: When making the switch to solar power, it's crucial to keep an open line of communication with your solar panel installer. Make sure you understand how the installation process works and the project timeline.
  • Contract: Though reading through a contract can be tedious, it's important to do it thoroughly so you can make sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been in business for many years most likely provide good-quality solar panel installation and expertise.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Although there are many options for which brand of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you peruse their list of options before deciding.

EcoWatch's Oak Brook, IL Solar Cost FAQs

How much does it cost to install solar panels in Oak Brook?

This is a hard question to answer precisely, because the cost depends on a few different factors. Broadly 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 higher quality 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.

What other factors should I consider aside from cost when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

Does Oak Brook have a net metering program?

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 electricity bills.

How long do solar panels last in Oak Brook?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency.
