Factors that Affect Solar Panel Costs in Stonington

There are many factors 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 installs your solar panels.

Solar Equipment

When it comes to estimating the cost of solar panels in Stonington, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can figure out by looking at past electricity bills. Your overall cost can increase by around $2,800 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Stonington, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Most solar companies in Stonington offer solar loans, which reduce your upfront costs of installing a solar system. You'll have to consider the long-term cost of financing options, including the total interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

The solar company you hire to handle your switch to renewable energy can play a role in your total costs. There are about 3 solar panel companies operating throughout Stonington, and each can charge varying amounts for labor and equipment. You may come across national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

The solar installer you go with will affect not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should consider, such as:

  • Contract: Even though reading through a contract can take a lot of time, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Installation Process: Get details from your solar installer about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
  • 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 hire.
  • 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 likely has a good reputation and is qualified to install your solar system. Another way you can look into your installer's reputation is by reading reviews.

EcoWatch's Stonington, CT Solar Cost FAQs

What is the average cost of installing solar panels in Stonington?

The average cost of solar panels in Stonington is about $14,000 for a 5-kW system and $28,000 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you consume.

Is cost the most important consideration when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is making the switch to solar worth it?

Solar panels can be a beneficial investment for lots of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

How long do solar panels last in Stonington?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
