Factors that Affect Solar Panel Costs in Westerly

There are many factors that can affect your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $2,840 per kilowatt in Westerly. 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 are often more expensive 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 will be looking at 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

If paying for a solar system out of pocket is out of reach, solar loans are a solid route because they lower your upfront costs and let you pay for your system over five to seven years on average. When estimating your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

The final key cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Westerly, you'll have plenty of options to choose from, but each comes at various price points for labor and equipment. 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 come at a higher cost. It's best to do some research and decide on the company that has the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

There are a lot of companies to choose from in Westerly, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:

  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. While there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to take a look at their list of offerings before making your decision.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be completed and how long it will take.
  • Reputation: Solar companies that have great reviews from their customers and that have been operating for many years most likely provide quality solar panel installation and expertise.

EcoWatch's Westerly, RI Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on a variety of factors. Generally speaking, it costs about $14,200 for a 5-kW system and $28,400 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you choose a smaller solar panel system or less efficient solar panels.

What other factors should I consider in addition to cost when buying solar panels?

Cost is a crucial factor to consider, but whether it's the most important for you depends on why you decided to go solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to think about are the quality and durability of your solar panels.

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

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

How long do solar panels last in Westerly?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency.
