Factors that Affect Solar Panel Costs in Thornton

Though the average cost of a solar system in Thornton is $12,211, your final cost may be above or below the average. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

One of the most important 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 power your household uses, the larger your system will likely need to be. You can expect to pay around $2,730 per kilowatt in Thornton. There are several different solar panel brands and the one you choose also affects the cost. In general, the brands that offer higher efficiency tend to also be more expensive. Plus, the type of equipment you choose 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 popular choice because they reduce your upfront costs and let you pay for your system over five to seven years on average. 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 can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Thornton is the company you get to install your solar panel system. Similar to choosing a company to renovate your kitchen, for instance, you'll have no shortage of solar installers that offer a range of services at different price points. Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and go with the company that offers the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

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

  • Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, durability and efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
  • Reputation: Solar companies that have great reviews from their customers and that have been operating for many years most likely provide high-quality solar panel installation and expertise.
  • Contract: It's important to read through your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Warranty: If you're worried about the longevity of your solar panels, verifying that your company offers a 25-year, all-inclusive warranty can help put you at ease.

EcoWatch's Thornton, IL Solar Cost FAQs

What is the average cost of installing solar panels in Thornton?

The average cost of solar panels in Thornton is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Thornton?

Leasing solar panels can be an option if you can't afford to pay upfront or secure 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.

Can solar panels completely eradicate my power bills?

Solar panels can potentially eliminate your electricity bills depending on your location and the efficiency of your system. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $707.72 per year.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is how much 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.
