Factors that Affect Solar Panel Costs in New London
Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few primary factors that determine your overall cost in New London: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
The size of the solar panel system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $4,220. There are a lot of different solar panel brands and the one you choose also changes the cost. In general, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you’re looking to install 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
Many homeowners find the average cost of solar in New London to be too costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans remarkably decrease upfront costs in most cases, but they also result in a higher cost over time because of interest.You’ll have to consider the long-term cost of loans, 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 principal cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The solar company you choose will play a role in your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor.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 cost more. It’s best to do some research and go with the company that has the products, warranties and services you’re looking for and also is within your budget.

- Warranty: Warranties that provide coverage for defective panels and repairs over a couple decades are the best you can get in the business, and offering that kind of warranty is one indication of a quality company.
- Installation Process: Make sure you’re aligned with the company regarding how the installation process will go and what needs to be done before your solar system is installed, such as updating your electrical system or roof.
