The Cost and Benefits of Solar in Oak Brook
Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to install your system. Some key factors that affect the cost of installing a solar panel system on your home and how much it could save you over time are:
- Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can result in an average of $13,000 of savings over 20 years.
- The model of solar panels you can afford: This is dependent on how much you're willing to spend upfront.
- Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
- Energy consumption: Solar may be too pricey an option for homes that don't use a lot of energy a month.
Thanks to the cost of solar panels being lower than before as well as local and federal solar incentives, they are a cost-effective investment for most homeowners.

Solar Incentives in Oak Brook
There are many reasons why going solar is a great investment. One of them consists of some government incentives you can take advantage of. Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much you paid for your solar installation on your tax return, lowering the amount of taxes you owe that year. Additionally, there may be some state and city incentives you can benefit from too. Take a look at our article on solar incentives to learn what incentives you can take advantage of.
Environmental Impact of Switching to Solar in Oak Brook
One of the best reasons to embrace solar energy is to reduce your reliance on traditional energy sources like burning fossil fuels, which are damaging for the environment. But how much can switching to solar actually affect the environment? A significant thing to keep in mind is your overall carbon footprint. For example, if you have a long commute, your footprint may be bigger, so adopting solar energy for your home can help offset that. Though solar panel production emits carbon dioxide, the panels make up for it by considerably lowering the amount of CO2 you would have released if you still used traditional energy. In Oak Brook, you can reduce your carbon footprint by 90 pounds a year with solar panels. For people who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Oak Brook, IL Solar Company Rankings FAQs
What is the best solar panel installation company in Oak Brook?
The top local solar company in Oak Brook is SunRise Solar Attic Fans, with a rating of 5.00 stars.
What are the biggest pros and cons of going solar?
A few of the biggest pros are that it lowers your electricity bills, it's good for the environment, and it provides a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels aren't always aesthetically pleasing.
Is it worth putting solar panels on my home?
Solar panels can be a great investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already fairly low, solar panels might not be for you.
When is the best time of year to install solar panels?
Despite summer being the most common time people install solar panels, the optimal time is actually winter. You can save money since there's less demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.
