Factors that Affect Solar Panel Costs in Sudbury

Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few major factors that will push your cost above or below the average in Sudbury: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

The size of the solar energy system you need for your household is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,940. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Sudbury, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of 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

For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are offered by most installers in Sudbury, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable. 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're only able to 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 securing a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The solar panel installation company you pick will affect your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Some companies only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and find a company that offers the products, warranties and services you're looking for and also fit into 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 models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Contract: Before signing a contract with a solar installer, be sure to look it over carefully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • 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 most likely has a good reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Installation Process: Make sure you're aligned with the installer in regard to how the installation process will go and what you need to do before your solar panels are installed, such as repairing your electrical system or roof.
  • Solar Panel Brands: Different companies carry different brands and types of panels. If you prefer a specific brand, make sure the solar installer you're considering has it.

EcoWatch's Sudbury, MA Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a few different factors. Broadly 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 cost more if you want extra solar equipment or higher quality panels, or if you have above-average energy consumption. On the flip side, you can spend less if you go with a smaller solar panel system or less expensive solar panels.

Can you get solar panels for free in Sudbury?

You can't get solar panels for free in Sudbury. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd prefer to own your solar panels, you can finance them with a solar loan.

Is switching to solar power worth it?

Solar panels can be a beneficial investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already pretty low, solar panels might not be for you.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy consumption 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. The average household has to install between 20 and 35 panels to account for their typical energy usage.
