Factors that Affect Solar Panel Costs in Millis

Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few primary factors that determine your overall cost in Millis: 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 panel system you need for your household, which is measured in kilowatts, 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. The kind of solar panels and equipment you choose is another factor that will significantly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Furthermore, solar equipment goes beyond just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking into a solar system that's in your budget.

Solar Financing Terms

If paying for solar panels out of pocket is out of reach, solar loans are an affordable route because they cut back your upfront costs and allow you to pay for your system over five to seven years on average. When considering your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

The solar installer you choose to handle your switch to green energy can play a role in your total costs. There are about 3 solar installation companies in Millis, and each can charge varying amounts for labor and equipment. Companies that 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 provides the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

There are many companies to choose from in Millis, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be difficult, so here are some tips to help you decide:

  • 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.
  • Contract: Review the contract terms closely to make sure you understand how much it will cost, project timeline rebates and warranties.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will be carried out, as well as important factors like the completion timeline.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it 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.
