Factors that Affect Solar Panel Costs in Prospect Heights

Even though the average cost of a solar system in Prospect Heights is $12,211, your actual cost may be above or below the average. There are quite a few factors that can have a major impact on the cost of a solar system installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. That's why it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Prospect Heights, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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

Most solar companies in Prospect Heights offer solar loans, which reduce your upfront costs of installing solar. It's wise to include the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, 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 choose to handle your switch to clean energy can play a role in your total costs. There are about 3 solar installation companies in Prospect Heights, and each can charge varying amounts for labor and equipment. Larger national companies usually have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the type of solar panels and the company you choose greatly impacts your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. While there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of options before making your decision.
  • Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you should know with your solar installer, such as what permits you should secure and what the project timeline is.
  • Contract: Though reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from past customers.

How often do you have to replace solar panels?

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 the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
