Factors that Affect Solar Panel Costs in Sandwich

The cost of installing a solar system in Sandwich can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is the size of the system your household needs, 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 key factors is the system size. Solar power systems with higher efficiency or power generation use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,940. There are a lot of different solar panel brands and the one you choose also affects the cost. In many cases, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you're looking to get 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 solar panels out of pocket can be difficult. Solar loans are offered by most installers in Sandwich, which can reduce, or in some cases eliminate, your upfront costs to make solar more accessible. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

A final factor to consider when trying to estimate the cost of solar for your home or business in Sandwich is the company you choose to install your PV system. Similar to choosing a company to renovate your kitchen, for instance, you'll have no shortage of solar installers that offer a range of services at different price points. The company's size sometimes plays the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more resources and bulk 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 promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

There are a lot of companies to choose from in Sandwich, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:

  • Warranty: A quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: Before signing a contract with a solar installer, be sure to look it over completely so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Even though there are many options for which model of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to take a look at their list of options before deciding.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like EcoWatch.

EcoWatch's Sandwich, MA Solar Cost FAQs

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

The average cost of solar panels in Sandwich is about $14,700 for a 5-kW system and $29,400 for a 10-kW system before the ITC, but the real cost will depend on stuff like the model of solar panels you want, what size system you need and how much energy you use.

Is cost the most important consideration when buying solar panels?

The upfront cost is a very important factor to consider, but whether it's the most important for you depends on your reasons for going solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

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

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Sandwich, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you'll want to contact a local solar installer to see how many panels can fit on your roof.

How many solar panels do I need to power my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
