Factors that Affect Solar Panel Costs in Old Greenwich

The cost of installing a solar system in Old Greenwich can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The size of the solar energy system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,750. There are many different solar panel brands and the one you choose also changes the cost. Usually, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar companies in Old Greenwich have solar loans, which reduce the initial cost of installing a solar system.However, the interest on solar loans also adds to your total costs, so it’s important to consider that as well. You can always reduce the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

The remaining significant cost factor you should consider is the installer you choose. Given the booming popularity of green energy solutions in Old Greenwich, you’ll have lots of options to choose from, but each comes at different price points for labor and equipment.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and go with the company that provides 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 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 installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by past customers and solar experts like the EcoWatch team.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you opt for.
  • Warranty: A comprehensive, long-term warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
  • Installation Process: Make sure you’re on the same page with the company regarding how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
