Factors that Affect Solar Panel Costs in Medfield

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

Solar Equipment Size

The size of the system you need is one of the largest factors that affects the overall cost of going solar. Because of that, it's important to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use. There are a lot of different solar panel brands and the one you pick also affects the cost. Usually, the brands that offer higher efficiency tend to also be more expensive. Additionally, the type of equipment you choose 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

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

Solar Panel Installation Company

The solar company you opt for to handle your switch to solar energy can play a role in your total costs. There are about 3 solar installation companies operating throughout Medfield, and each can charge different amounts for labor and equipment. Companies that only sell products with high efficiency and therefore a higher price point — 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 go with the company that provides the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

The solar installer you opt for will impact not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should keep in mind, such as:

  • Contract: It's important to read your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system's energy production.
  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
  • 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 company, such as what permits you should acquire and how long the project will take.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and how much efficiency they need. Although there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of offerings before making your decision.
