Factors that Affect Solar Panel Costs in South Rock Island

There are a number of criteria that can influence 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 cost of solar panels varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). 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. The brand of solar panels and equipment you get is another factor that will considerably affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Further, solar equipment is more than just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that falls within your budget.

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 South Rock Island homeowners choose to finance their solar panel systems to make paying for solar more affordable. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

The last significant cost factor you should consider is the installer you choose. Given the booming popularity of clean energy solutions in South Rock Island, you'll have many options to choose from, but each comes at varying 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 come at a higher cost. It's best to do some research and find a company that offers the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Installation Process: Make sure you're aligned with the company with regard to how the installation process will go and what you need to do before your solar panel system is installed, such as repairing your electrical system or roof.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you hire.
  • Contract: It's important to read through your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
