Factors that Affect Solar Panel Costs in Holliston

For many Holliston homeowners, the decision to go solar rests on cost. However, the range of solar installation costs can be quite wide in Holliston, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $4,060.The model of solar panels and equipment you want is another factor that will greatly influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Moreover, solar equipment goes beyond just the solar panels themselves. You’ll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that falls within your budget.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are available from most installers in Holliston, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible.It’s a good idea to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay back the loan.

Solar Panel Installation Company

The solar company you hire to handle your switch to clean energy can play a role in your total costs. There are about 3 solar panel companies in Holliston, and each can charge varying amounts for labor and equipment.Companies that 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 with an above-average cost. It’s best to do some research and go with the company that offers the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose has an impact on your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: Make sure you’re aligned with the company regarding how the installation process will go and what you need to do before your solar system is installed, such as repairing your electrical system or roof.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to do the job well. Another way you can research your installer’s reputation is by reading reviews.
  • Contract: When looking over your solar installer’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • Solar Panel Brands: Different companies have different brands and types of panels. If you want a specific brand, make sure the solar company you’re considering has it.

EcoWatch's Holliston, MA Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a few different 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 be more expensive if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

What other factors should I consider aside from cost when buying solar panels?

The initial cost is a key 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 take into account are the quality and durability of your solar panels.

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

Each state has some kind 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 long do solar panels last in Holliston?

On average, solar panels can last 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 level of energy production.
