Factors that Affect Solar Panel Costs in Naperville

For many Naperville homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Naperville, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. Because of that, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.There are a lot of different solar panel brands and the one you pick also affects the cost. In many cases, the brands that offer higher efficiency tend to also be more expensive. In addition, the type of equipment you’re looking to get can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar companies in Naperville offer solar loans, which reduce the initial cost of installing a solar system.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 can only 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 last major cost factor you should consider is the installer you choose. Given the booming popularity of renewable energy solutions in Naperville, you’ll have plenty of options to choose from, but each comes at various price points for labor and equipment.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and decide on the company that provides the products, warranties and services you’re looking for and also is within your budget.

How much does it cost to install solar panels in Naperville?

The average cost of solar panels in Naperville is about $18,800 for a 5-kW system and $37,600 for a 10-kW system before the ITC, but the real cost will depend on things like the model of solar panels you want, what size system you need and how much energy you consume.

Are solar panels free in Naperville?

You can’t get solar panels for free in Naperville. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d rather own your solar panels, you can finance them with a solar loan.

Does Naperville have a net metering program?

Most states have net metering programs of some kind. Through these, you can either be compensated for the extra power your system produces or or receive credits to put toward future electricity bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
