Factors that Affect Solar Panel Costs in Thornton

For many Thornton homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Thornton, with typical prices between $20,000 to $40,000. There are a few factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment Size

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the notable factors is the system size. Solar power systems that have better efficiency or power generation use 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. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Thornton, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are a popular option because they lower your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. When figuring out your overall cost, you should also calculate the interest you'll pay if you decide on a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar company you opt for to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies operating in Thornton, and each can charge varying amounts for labor and equipment. The size of the company can sometimes play the most considerable role in your costs. Larger national companies, like SunPro and Sunrun, often have lower prices because they have greater resources and better 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 promotion can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels

The solar company you go with will affect not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should keep in mind, including:

  • Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and how much efficiency they need. Even though there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so be sure to take a look at their list of offerings before deciding.
  • Contract: Although 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 how part repairs and replacements will be handled.
  • Installation Process: When making the switch to solar energy, it's important to maintain an open line of communication with your solar panel installer. Make sure you understand how the installation process will go and the completion timeline.
  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.

EcoWatch's Thornton, IL Solar Cost FAQs

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

This is a difficult 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 be more expensive if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. On the flip side, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Is cost the most important consideration when buying solar panels?

The initial cost is a key factor to consider, but whether it's the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is it worth going solar in Thornton?

Solar panels can be a great 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 electricity bills are already pretty low, solar panels might not be for you.

What solar power system size is right for my home?

To figure out what solar panel system size 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 home will need 20 to 35 panels.
