Factors that Affect Solar Panel Costs in Marlborough

For many Marlborough homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Marlborough, with typical prices between $20,000 to $40,000. There are a few factors that significantly 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 a variety of factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater 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 kind of solar equipment you choose can increase or decrease your cost 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 over time on your energy bills. Additionally, extra products, such as solar batteries, can bring your total well above the Marlborough average.

Solar Financing Terms

Many homeowners find the average cost of solar in Marlborough to be too steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to a higher cost over time due to interest. It's a good idea to factor the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

Finally, the company you get to install your solar panel system can impact the cost. Marlborough's solar companies all have different labor costs and add varying upcharges to equipment. The company's size sometimes plays the most considerable role in your costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, such as:

  • Contract: When reading over your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios like a system component breaking or if the company goes out of business.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like the EcoWatch team.

EcoWatch's Marlborough, MA Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $14,700 for a 5-kW system and $29,400 for a 10-kW system after the ITC is applied. It will be more expensive if you want other solar equipment or higher quality panels, or if you have above-average energy needs. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in Marlborough?

Leasing solar panels can be an appealing choice, because it typically comes with low or $0 upfront payments. The drawback 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 tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

How will having solar panels impact how much my home is worth?

Installing solar panels on your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Marlborough is currently $348,500, which means you can expect a value of about $14,288 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Marlborough is a rewarding investment.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
