Factors that Affect Solar Panel Costs in Rock Island

Although the average cost of a solar system in Rock Island is $12,326, your actual 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

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,730. The brand and kind of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a big investment. That's why many Rock Island homeowners choose to finance their solar panel systems to make paying for solar more affordable. You'll have to consider the long-term cost of loans, including the amount of 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 principal 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 last significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Rock Island, you'll have plenty of options to choose from, but each comes at different price points for labor and equipment. Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and find a company that offers the products, warranties and services you're looking for and also fits within your budget.

How to Save on Solar Panels

Since the model of solar panels and the company you choose significantly affects your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: When going solar, it's necessary to keep an open line of communication with your solar panel company. See to it that you understand how the installation process works and the project completion timeline.
  • Warranty: Companies typically 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 well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can research your installer's reputation is by reading reviews.
  • Solar Panel Brands: Different companies will offer various brands and kinds of panels. If you want a specific brand, make sure the solar panel company you're considering has it.

EcoWatch's Rock Island, IL Solar Cost FAQs

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

This is a difficult question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have above-average energy consumption. On the flip side, you can spend less if you want a smaller solar panel system or less expensive solar panels.

What other factors should I consider in addition to cost when buying solar panels?

Cost is certainly one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.

Is switching to solar power worth it?

Whether or not solar panels are worth it depends on a variety of factors like local electricity rates and how much direct sunlight your roof gets.

How often do you have to replace solar panels?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
