Factors that Affect Solar Panel Costs in Rock Falls

There are a number of criteria that can determine your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The size of the solar panel system you need for your home, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $2,730. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your electric bills. Additionally, add-on products, such as solar batteries, can bring your total well above the Rock Falls average.

Solar Financing Terms

If paying for solar panels out of pocket is out of reach, solar loans are a solid option because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. Although solar loans make going solar more accessible for Rock Falls homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar installer you go with to handle your switch to green energy can play a role in your total costs. There are about 3 solar panel companies in Rock Falls, and each can charge varying amounts for labor and equipment. The company's size sometimes plays the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to more 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 discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

Since the brand of solar panels and the installation company you choose has an impact on your costs and your system's durability and efficiency, it's important to select the right ones for you. Here are some things to keep in mind to help with your decision:

  • Reputation: Make sure your solar system installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Solar Panel Brands: The kind of solar panel you'd like to get plays a role in which company you should go with, since different companies have access to different panels.
  • Installation Process: Make sure you're aligned with the company in regard to how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.
  • Contract: When looking through your solar installer's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios such as a system part breaking or the company going out of business.

EcoWatch's Rock Falls, IL Solar Cost FAQs

How much does it cost to install solar panels in Rock Falls?

The average cost of solar panels in Rock Falls is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Rock Falls?

Leasing solar panels can be an option if you can't afford 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 it worth going solar in Rock Falls?

Whether or not solar panels are worth it depends on some different factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
