The Cost and Benefits of Solar in Wilmington
For many homeowners, the decision to invest in a solar energy system depends the most on the cost. Some important factors that dictate how much it will cost to install solar panels on your home and how much money you could save over time are:
- How much sunlight your roof gets: If your rooftop doesn't get a lot of direct sunlight, your solar panel system won't be able to produce as much energy, which will leave you with lower savings on electricity bills than a roof that gets lots of sunlight.
- Your income and budget: This shapes what model of solar panels you can purchase.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can take advantage of. Additionally, you can save about $13,000 over 20 years on your utility bills, before factoring in incentives.
- Your power bills: This will dictate your savings. In Wilmington, the average homeowner can save about $900 a year on their electricity bills.
Though a solar panel system costs a good chunk of money upfront, it can save you much more over the lifespan of your panels. The question of how much, though, depends on a number of factors, such as the angle of your roof and incentives.

EcoWatch's Wilmington, IL Solar Company Rankings FAQs
Which solar panel installer is the best near me?
In Wilmington, SunRise Solar Attic Fans is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your house.
Are solar panels actually bad for the environment?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 13.6 years, but your solar payback period will depend on your utility costs. The more your typical electricity bill, the faster your solar panel system will pay for itself.
What is the best kind of solar panel?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much energy generation you want.
