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
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That's why it's a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use. The kind of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Furthermore, solar equipment goes beyond just the solar panels themselves. You'll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that falls within your budget.
Solar Financing Terms
Most solar companies in Oak Brook have solar loans, which reduce your upfront costs of installing a solar system. Although solar loans make adopting solar energy more accessible for Oak Brook homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
The remaining key cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Oak Brook, you'll have plenty of options to choose from, but each comes at various price points for labor and equipment. Larger national companies usually have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to 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 decide on the right company for you, here are some tips to keep in mind:
- Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
- 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 solid reputation and is qualified to get the job done well. Another way you can look into your installer's reputation is by reading reviews.
- Installation Process: Homeowners should understand how exactly the installation process will go, as well as important factors like the project completion timeline.
- Contract: When looking over your solar company's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios like a system component breaking or the company going out of business.

EcoWatch's Oak Brook, IL Solar Cost FAQs
How much does it cost to install solar panels in Oak Brook?
This is a difficult question to answer exactly, because the cost depends on many 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 additional solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Is cost the most important thing to think about when buying solar panels?
The initial cost is a very important factor to consider, but whether it's the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.
Can you sell solar power back to the grid in Oak Brook?
The majority of states have net metering programs of some kind. Through these, you can either receive compensation for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.
How many solar panels should I get to power 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 take a 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.
