Factors that Affect Solar Panel Costs in Weston

The cost of installing a solar system in Weston can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

The cost of solar panels 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 greater efficiency or power production use 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 $4,060.The brand and kind of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are available from most installers in Weston, which can reduce, or in some cases totally eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also increases your total costs, so it’s crucial to take that into consideration as well. You can always bring down the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

The solar installer you hire to handle your switch to green energy can play a role in your total costs. There are about 3 solar installation companies operating in Weston, and each can charge different amounts for labor and equipment.The company’s size sometimes plays the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices due to greater resources and better 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 names.

  • Contract: It’s important to look over your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running smoothly and save you money on part replacement and repairs.

EcoWatch's Weston, MA Solar Cost FAQs

How much does it cost to install solar panels in Weston?

This is a hard question to answer exactly, because the cost depends on many factors. Broadly 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 cost more if you want additional solar equipment or higher quality panels, or if you have above-average energy consumption. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Should I lease or buy solar panels in Weston?

Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to 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 savings from going solar.

How much can I save on energy bills after switching to solar?

Solar panels can potentially eliminate your electricity bills depending on where you’re located and the efficiency of your system. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $1,136.56 per year.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy needs and the amount of sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need.
