There are a few factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment

Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Plymouth, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited 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
Most solar companies in Plymouth provide solar loans, which reduce your upfront costs of installing solar.When figuring out your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Different companies will bill different amounts for the equipment and labor.Additionally, some companies in Plymouth know more about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

EcoWatch's Plymouth, MA Solar Cost FAQs
What is the average cost of installing solar panels in Plymouth?
The average cost of solar panels in Plymouth is about $20,300 for a 5-kW system and $40,600 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the type of solar panels you want, what size system you need and how much energy you consume.
Is it better to lease or buy solar panels in Plymouth?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property 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.
Is switching to solar power worth it?
Solar panels can be a great investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already fairly low, solar panels might not be for you.
How long do solar panels last in Plymouth?
Even 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 the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
