Factors that Affect Solar Panel Costs in Charlestown

While the average cost of a solar system in Charlestown is $10,287, your actual cost may be above or below the average. There are many factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to pay about $2,910 per kilowatt in Charlestown. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Charlestown, where sunlight isn't as abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited 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 solar out of pocket can be financially overwhelming. Solar loans are available from most installers in Charlestown, which can bring down, or in some cases eliminate, your upfront costs to make solar more affordable. When considering your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Charlestown is the company you choose to install your solar system. As with choosing a company to build a deck or pool, for example, there's no shortage of solar installers that provide a range of services at different costs. The size of the company can sometimes play the most considerable role in the cost. Larger national companies, like SunPro and Sunrun, often have lower prices 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 discount can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

The solar installer you go with will affect not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should keep in mind, such as:

  • Contract: Read the contract terms carefully to make sure you understand how much it will cost, completion timeline rebates and warranties.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you choose.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a couple decades are the best you can get in the business, and offering such a warranty is one sign of a good company.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
