Factors that Affect Solar Panel Costs in Millis

There are several criteria that can influence your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment Size

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size. Solar power systems that have greater efficiency or power generation 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. There are several different solar panel brands and the one you pick also changes the cost. In general, the brands that offer higher efficiency tend to also be more expensive. In addition, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are an affordable route because they reduce your upfront costs and let you pay for your system over a term of, on average, between five and seven years. 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 more than the principal 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 last significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of sustainable energy solutions in Millis, you'll have a great number of options to choose from, but each comes at different price points for labor and equipment. Larger national companies generally have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can look into your installer's reputation is by reading reviews.
  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar installer, such as what permits you should secure and how long the project will take.
  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.

EcoWatch's Millis, MA Solar Cost FAQs

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

This is a difficult 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 be more expensive if you want other solar equipment or more efficient panels, or if you have higher-than-average energy usage. On the flip side, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Can you get solar panels for free in Millis?

Solar panels aren't free in Millis, but there are some options that can make getting them more affordable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.

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

Each state has some form 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 give you credit toward your future utility bills.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home uses 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.
