Factors that Affect Solar Panel Costs in Des Peres

There are several criteria that can influence your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to pay around $2,590 per kilowatt in Des Peres. The kind of solar panels and equipment you choose is another factor that will significantly impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Plus, solar equipment consists of more than just the solar panels themselves. You'll also need to think 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

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are available from most installers in Des Peres, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

The last significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of renewable energy solutions in Des Peres, you'll have many options to choose from, but each comes at various price points for labor and equipment. Some companies only sell high-quality, high-efficiency and high-price 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 decide on the company that provides the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

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

  • Installation Process: Make sure you're on the same page with the installer regarding how the installation process will go and what needs to be done before your solar system is installed, such as updating or replacing your electrical system or roof.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to get the job done well. Another way you can research your installer's reputation is by reading reviews.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
  • Contract: Read the contract terms carefully to make sure you understand the overall cost, project timeline incentives and warranties.
