Factors that Affect Solar Panel Costs in Marlborough

For many Marlborough homeowners, the decision to adopt solar energy comes down to 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 numerous factors that greatly influence the price you'll pay, which we'll go over below.

Solar Equipment Size

When it comes to estimating the cost of a solar energy system in Marlborough, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy consumption, which you can determine by looking at past electricity bills. Your overall cost can increase by about $2,940 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Marlborough, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, 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

If paying for a solar system in cash is too expensive, solar loans are a popular route because they reduce your upfront costs and allow you to pay for your system over five to seven years on average. You'll have to consider the long-term cost of financing options, including the total interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The final major cost factor you should consider is the installer you choose. Given the booming popularity of green energy solutions in Marlborough, you'll have many options to choose from, but each comes at varying price points for labor and equipment. The company's size sometimes plays the most significant role in your costs. Larger national companies, like SunPro and Sunrun, often have lower pricing due to access to greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down 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 about 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.
