Factors that Affect Solar Panel Costs in Joliet

For many Joliet homeowners, the decision to go solar comes down to 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 several factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Joliet, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy usage, which you can gauge by looking at past energy bills. Your total cost can increase by about $2,730 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Joliet, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are a popular route because they cut back your upfront costs and allow you to pay for your system over five to seven years on average. It's a good idea to factor the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

The solar company you go with to handle your switch to clean energy can play a part in your total costs. There are about 3 solar panel companies operating in Joliet, and each can charge varying amounts for labor and equipment. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

There are many 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 has varying levels of quality, durability and efficiency. They will come at different price points as well. The company you choose affects which solar panel brands you have access to.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been operating for many years in most cases provide good-quality solar panel installation and expertise.
  • Installation Process: One of the most important things to understand when going solar 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 what the project timeline is.
  • Contract: Before signing a contract with a solar installer, be sure to read it through completely so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
