Factors that Affect Solar Panel Costs in Groton

Even though the average cost of a solar system in Groton is $11,856, your final cost may be above or below the average. There are several factors that can have a major impact on the cost of a solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

When it comes to estimating the price of solar panels in Groton, 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 determine by looking at past electricity bills. Your overall cost can increase by around $3,750 for each additional kilowatt you need.The model of solar panels and equipment you choose is another factor that will largely influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Furthermore, solar equipment goes beyond just the solar panels themselves. You’ll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that falls within your budget.

Solar Financing Terms

Many homeowners find the average cost of solar in Groton to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides access to financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to paying more over time due to interest.It’s a good idea to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

Lastly, the company you hire to install your solar system can impact how much you pay. Groton’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.
