Factors that Affect Solar Panel Costs in Winnetka

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

Solar Equipment

When it comes to estimating the cost of solar panels in Winnetka, 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 figure out by looking at past power bills. Your overall cost can increase by around $2,730 for each additional kilowatt you need. There are a lot of different solar panel brands and the one you pick also changes the cost. In many cases, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you want to install can affect your total cost. If you only 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 solar panels out of pocket is too expensive, solar loans are an affordable route because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. It's wise to include 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

A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Winnetka is the company you hire to install your solar system. Similar to choosing a company to build a deck or pool, for example, there's no shortage of solar installers that provide a range of services at different costs. Larger national companies generally 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 additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the kind of solar panels and the installer you choose significantly influences your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Contract: Before you sign a contract with a solar installer, be sure to look it over fully so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Installation Process: Homeowners should make sure they know how exactly the installation process will be carried out, as well as important factors like the project completion timeline.
  • Warranty: Each company may offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected 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 get the job done well. Another way you can look into your installer's reputation is by reading reviews.
