Factors that Affect Solar Panel Costs in Westerly
For many Westerly homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Westerly, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
When it comes to estimating the cost of a solar energy system in Westerly, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past power bills. Your total cost can increase by about $4,070 for each additional kilowatt you need.The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Most solar installers in Westerly have solar loans, which reduce the initial cost of installing solar.You’ll have to consider the long-term cost of financing options, including the amount of 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 above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The remaining key cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Westerly, you’ll have a great number of options to choose from, but each comes at varying price points for labor and equipment.The company’s size sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to more resources and better pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger names.

EcoWatch's Westerly, RI Solar Cost FAQs
What is the average cost of installing solar panels in Westerly?
This is a tough question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $20,350 for a 5-kW system and $40,700 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or more efficient panels, or if you have above-average energy consumption. Conversely, you can spend less if you go with a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in Westerly?
Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.
Do solar panels increase the value of your home?
Solar panels can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Westerly is currently $529,386, which means you can expect a value of about $21,705 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Westerly is a worthwhile investment.
How often do you have to replace solar panels?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
