Factors that Affect Solar Panel Costs in Winnetka

There are a number of factors that can affect your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

When it comes to estimating the price of a solar energy system 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 primarily based on your home's energy usage, which you can figure out by looking at past electricity bills. Your overall cost can increase by around $2,730 for each additional kilowatt you need. There are many different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you're looking to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a significant investment. That's why many Winnetka homeowners decide to finance their solar panel systems to make paying for solar more affordable. You'll have to consider the long-term cost of financing options, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar installer you choose will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. The size of the company sometimes plays the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

Since the type of solar panels and the installation company you choose significantly affects your costs and your system's durability and efficiency, it's important to select 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, make sure you read it through fully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Warranty: A high-quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Reputation: Solar installers that have great reviews from their customers and that have been in business for many years most likely offer high-quality solar panel installation and expertise.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you opt for.

EcoWatch's Winnetka, IL Solar Cost FAQs

How much does it cost to install solar panels in Winnetka?

This is a hard question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or higher quality panels, or if you have higher-than-average energy needs. On the other hand, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Should I lease or buy solar panels in Winnetka?

Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.

Is going solar worth it?

Solar panels can be a fruitful investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already fairly low, solar panels might not be for you.

How many solar panels should I get to power my home?

To figure out how many solar panels you need, you should find out how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
