Factors that Affect Solar Panel Costs in Wilmette

For many Wilmette homeowners, the decision to go solar comes down to cost. However, the range of solar installation costs can be quite wide in Wilmette, with typical prices between $20,000 to $40,000. There are several factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,730. The kind of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Further, solar equipment consists of more than just the solar panels themselves. You'll also need to make decisions about 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 falls within your budget.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in Wilmette, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable. It's wise to factor the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Wilmette is the company you get to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there's no shortage of solar installers that offer a range of services at different costs. Larger national companies usually have lower costs, but some local companies undercut 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 vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a lot of 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:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panel system running smoothly and save you money on part replacement and repairs.
  • Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
  • Contract: When reading through your solar company's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
