Factors that Affect Solar Panel Costs in Wilmette

While the average cost of a solar system in Wilmette is $16,818, your actual cost may differ. There are several factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to pay about $3,760 per kilowatt in Wilmette.There are several different solar panel brands and the one you choose also changes the cost. In general, the brands that have better efficiency tend to also cost more. Plus, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system in cash is too expensive, solar loans are a solid choice because they lower your upfront costs and let you pay for your system over five to seven years on average.However, the interest on solar loans also increases your all-in costs, so it’s crucial to take that into consideration as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

Finally, the company you choose to install your solar panels can affect how much you pay. Wilmette’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Wilmette are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose has an impact on your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Reputation: Long-standing companies likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and efficiency. They will come at different price points as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar panel system running for years to come and save you money on repairs and maintenance.
  • Contract: Even though reading through a contract can take a lot of time, it’s important to do it fully so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
