Factors that Affect Solar Panel Costs in Joliet

While the average cost of a solar system in Joliet is $12,364, your actual cost may differ. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend about $2,730 per kilowatt in Joliet. The brand of solar panels and equipment you want is another factor that will considerably impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Further, solar equipment goes beyond just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that's in your budget.

Solar Financing Terms

Most solar installers in Joliet provide solar loans, which reduce the initial cost of installing solar panels. 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 how long it'll take to pay back the loan.

Solar Panel Installation Company

The solar installer you opt for to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar installation companies in Joliet, and each can charge different amounts for labor and equipment. You may come across national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since picking a company can be difficult, we have some tips to help you, such as:

  • Contract: Even though reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be completed and what the project timeline is.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you go with.
  • Reputation: Make sure your solar panel installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like EcoWatch.
