Factors that Affect Solar Panel Costs in Groton

For many Groton homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Groton, with typical prices between $20,000 to $40,000. There are a number of factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. Because of that, it's important to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Groton, 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 more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar panels out of pocket can be challenging. Solar loans are offered by most installers in Groton, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more accessible. While solar loans make going solar more accessible for Groton homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar company you hire to handle your switch to solar energy can play a part in your total costs. There are about 3 solar panel companies operating in Groton, and each can charge varying amounts for labor and equipment. Companies that only sell products with high efficiency and therefore a higher price point — 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 find a company that provides the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since selecting a company can be a tough decision, we have some tips to help you, such as:

  • Installation Process: Make sure you're aligned with the company with regard to how the installation process will go and what you need to do before your solar panel system is installed, such as updating your electrical system or roof.
  • Solar Panel Brands: Different companies have various brands and types of panels. If you want a specific brand, make sure the solar installer you're considering has it.
  • Contract: When reading over your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
  • Reputation: Make sure your solar panel installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like EcoWatch.

EcoWatch's Groton, CT Solar Cost FAQs

How much does it cost to install solar panels in Groton?

The average cost of solar panels in Groton 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 like the type of solar panels you want, what size system you need and how much energy you consume.

Can you get solar panels for free in Groton?

You can't get solar panels for free in Groton. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd rather own your solar panels, you can finance them with a solar loan.

Can you sell solar power back to the grid in Groton?

Most states offer net metering programs of some kind. Through these, you can either receive compensation for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How many solar panels should I get to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
