Factors that Affect Solar Panel Costs in Westborough

While the average cost of a solar system in Westborough is $9,220, your final cost may be higher or lower than that. There are several factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more crucial things to consider.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,940. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more in the long run on your electric bills. Additionally, extra products, like solar batteries, can bring your total well above the Westborough average.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a significant investment. That's why many Westborough homeowners choose to finance their solar panel systems to offset upfront costs. Though solar loans make going solar more accessible for Westborough homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Westborough is the company you choose to install your solar panel system. As with choosing a company to install new cabinets, for example, there's no shortage of solar installers that provide a range of services at different costs. 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 with an above-average cost. It's best to do some research and choose a company that has the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Solar Panel Brands: Different companies offer different brands and models of panels. If you want a specific brand, make sure the solar installer you're considering has it.
  • Warranty: If you care about the durability of your solar panel system, making sure your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: When reading over your solar installer'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 if the company goes out of business.
  • Installation Process: Homeowners should make sure they know how exactly the installation process will go, as well as important factors like the project completion timeline.

EcoWatch's Westborough, MA Solar Cost FAQs

What is the average cost of installing solar panels in Westborough?

The average cost of solar panels in Westborough is about $14,700 for a 5-kW system and $29,400 for a 10-kW system before the ITC, but the real cost will depend on stuff like the kind of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in Westborough?

Leasing solar panels can be an option if you can't afford to 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 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.

Can solar panels eliminate my electricity bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners throughout Westborough, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you'll want to contact a local solar installer to see how many panels can fit on your roof.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
