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 equipment choices, financing options and the solar installer you choose.

Solar Equipment

Size is one of the largest factors that affects the overall cost of going solar. Because of that, it's important to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use. The model of solar panels and equipment you want is another factor that will largely impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Further, solar equipment is more than just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking into a solar system that's in your budget.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Oak Brook homeowners choose to finance their solar panel systems to make going solar more affordable. You'll have to consider the long-term cost of loans, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

The solar panel installation company you choose will play a role in your total cost to make the switch to solar . Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Oak Brook have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, 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

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 decide on the right company for you, here are some tips to keep in mind:

  • Solar Panel Brands: Different companies have different brands and models of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.
  • Installation Process: When making the switch to solar energy, it's essential to keep an open line of communication with your solar panel company. See to it that you understand how the installation process will go and the completion timeline.
  • Contract: Although reading through a contract can be tedious, it's important to do it fully so you can make sure you understand what services your solar company will provide and the terms of the warranty.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can research your installer's reputation is by reading reviews.

EcoWatch's Oak Brook, IL Solar Cost FAQs

What is the average cost of installing solar panels in Oak Brook?

This is a tough question to answer precisely, because the cost depends on a few different 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. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have above-average energy usage. On the other hand, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Is it better to lease or buy solar panels in Oak Brook?

Leasing solar panels can be an appealing choice, as it often 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 option if you want to maximize your savings.

Can solar panels completely eradicate my energy bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Oak Brook, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in Oak Brook?

On average, the lifespan of solar panels is 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 higher amount of energy production.
