Factors that Affect Solar Panel Costs in Joliet

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

Solar Equipment Size

The size of the system you need is one of the largest factors that determines the overall cost of installing solar panels. That's why it's a priority to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs. There are many different solar panel brands and the one you pick also changes the cost. Usually, the brands that are more efficient tend to also be more expensive. In addition, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a significant investment. That's why many Joliet homeowners opt to finance their solar panel systems to offset upfront costs. You'll have to consider the long-term cost of financing options, 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 getting a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Joliet is the company you get to install your solar panel system. Similar to choosing a company to build a deck or pool, for instance, there's no shortage of solar installers that offer a range of services for different budgets. The size of the company can sometimes play the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you select the right company for you, here are some tips to keep in mind:

  • Installation Process: One of the most important things to understand when adopting solar power is the installation process itself. Be sure to align on any details you need to know with your solar installer, such as what permits you should secure and how long the project will take.
  • Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years likely offer high-quality solar panel installation and expertise.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and energy needs. While there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to take a look at their list of offerings before making your decision.
  • Contract: Before signing a contract with a solar company, make sure to look it over completely so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.

EcoWatch's Joliet, IL Solar Cost FAQs

What is the average cost of installing solar panels in Joliet?

The average cost of solar panels in Joliet is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you consume.

Is cost the most important thing to think about when buying solar panels?

The initial cost is a key factor to consider, but whether it's the most important for you depends on why you decided to go solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

Does Joliet have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just give you credit toward your future utility bills.

How long do solar panels last in Joliet?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
