Factors that Affect Solar Panel Costs in Williamstown

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

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 energy your household uses, the larger your system will likely need to be. You can expect to spend around $3,530 per kilowatt in Williamstown.There are many different solar panel brands and the one you pick also changes the cost. Generally, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels in cash is too expensive, solar loans are a popular choice because they cut back your upfront costs and allow you to pay for your system over five to seven years on average.It’s a good idea to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

The solar installer you select will influence your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.The size of the company sometimes plays the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing due to more resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

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. Since choosing a company can be difficult, we have some tips to help you, such as:

  • Contract: It’s important to read your solar installer’s contract thoroughly to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can research your installer’s reputation is by reading reviews.
  • Installation Process: Get details from your solar installer about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
  • 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.

EcoWatch's Williamstown, NJ Solar Cost FAQs

Generally speaking, it costs about $17,650 for a 5-kW system and $35,300 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or higher quality panels, or if you have higher-than-average energy needs. On the other hand, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

What other factors should I consider other than cost when buying solar panels?
