Factors that Affect Solar Panel Costs in Westport
There are several criteria that can affect your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
One of the most important factors to consider when it comes to the cost of going solar 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 around $4,060 per kilowatt in Westport.The brand and type of equipment you want 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 have a higher price tag 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 extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Most solar companies in Westport provide solar loans, which reduce your upfront costs of installing solar panels.Even though solar loans make going solar more accessible for Westport homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar panel installation company you pick will affect your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor.Some companies only sell high-quality, high-efficiency and high-price 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 choose a company that provides the products, warranties and services you want and also is within your budget.

- Warranty: A comprehensive, long-term warranty can help keep your solar panel system running for a long time and save you money on part replacement and repairs.
- Reputation: Solar panel companies that have great reviews from their customers and that have been in business for many years most likely offer high-quality solar panel installation and expertise.

- Contract: When reading over your solar company’s contract, ask questions about any terms you’re not sure of and make sure you understand what happens in scenarios like a system component breaking or the company going out of business.

EcoWatch's Westport, MA Solar Cost FAQs
What is the average cost of installing solar panels in Westport?
This is a tough question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $20,300 for a 5-kW system and $40,600 for a 10-kW system after the ITC is applied. It will cost more if you want other 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 cheaper solar panels.
Should I lease or buy solar panels in Westport?
Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The downside 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 incentives and your home value won’t increase. Buying solar panels is a better option if you want to maximize your savings.
Does Westport have a net metering program?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future energy bills.
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 goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
