Factors that Affect Solar Panel Costs in Decatur

There are a number of factors 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 does the installation.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it's a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use. The solar equipment you choose can increase or decrease your cost 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, higher efficiency could save you more in the long run on your electric bills. In addition, add-on products, such as solar batteries, can bump up your total well above the Decatur average.

Solar Financing Terms

Most solar installers in Decatur provide solar loans, which reduce the initial cost of installing a solar system. It's a good idea to include the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it'll take to pay back the loan.

Solar Panel Installation Company

The solar installer you pick will affect your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor. Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should acquire and what the project timeline is.
  • Contract: Before you sign a contract with a solar installer, be sure to read it through fully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Solar Panel Brands: The model of solar panel you want to get plays a role in which installer you should go with, since different companies have different panels.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to get the job done well. Another way you can research your installer's reputation is by reading reviews.
