Factors that Affect Solar Panel Costs in Groton

For many Groton homeowners, the decision to go solar comes down to 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 numerous factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment Size

System size is one of the largest factors that influences the overall cost of installing solar panels. That's why it's a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Groton, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of 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

If paying for solar panels in cash is too expensive, solar loans are a popular route because they lower your upfront costs and allow you to pay for your system over five to seven years on average. 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're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The remaining significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of clean energy solutions in Groton, you'll have plenty of options to choose from, but each comes at various price points for labor and equipment. Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

EcoWatch's Groton, CT Solar Cost FAQs

What is the average cost of installing 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 real cost will depend on stuff such as the type of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Groton?

Leasing solar panels can be an appealing choice, as it typically comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Is it worth going solar in Groton?

Whether or not solar panels are worth it depends on some different factors like local electricity rates and the amount of direct sunlight your roof gets.

How long do solar panels last in Groton?

On average, solar panels can last 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 amount of energy production.
