The Cost and Benefits of Solar in Williamstown

Even though solar panels can help save you a decent chunk of change on power bills over time, it's important to take into consideration the upfront costs. A few important factors that determine the cost of installing solar panels on your home and how much money you could save over time are:

  • Your current energy bills: Solar panels can noticeably decrease, or entirely get rid of, your utility bills. In Williamstown, you can save an average of $83 a month.
  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • The type of solar panels you want to get: More efficient models are more costly, so that will affect your budget for your solar project.
  • Incentives: Those who purchase and install a solar energy system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $21,000 on your electricity bills over 20 years not including incentives.

Although a solar panel system costs a decent chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, including the size of your house and incentives.

Solar Incentives in Williamstown

Although a solar power system is typically a big investment, it can save you much money in the long term due to reduced utility bills and government incentives. These incentives mostly consist of cash rebates, tax benefits and/or solar renewable energy credits. They can reduce the cost of going solar by 30%, upwards of 50% depending on where you live. In our article on solar incentives, you can read about the incentives you qualify for in Williamstown.

Environmental Impact of Switching to Solar in Williamstown

Many want to do their part to help save the planet, which often is the chief motivation to install solar panels. You may be asking yourself — how much does making the switch do for the environment anyway? If your family uses a lot of energy, you can have an even greater impact on the planet by switching to solar energy. When you go solar, your carbon dioxide emissions can be reduced by about 40 pounds each year. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Williamstown, MA Solar Company Rankings FAQs

What is the most reputable solar installation company in Williamstown?

The highest-rated local solar company in Williamstown is Northeast Solar, with a rating of 5.00 stars.

What are a few of the biggest pros and cons of adopting solar power?

The advantages of solar power are that it can reduce or, in some cases, 100% eradicate your electricity bills, raise the value of your home and bring down your carbon footprint. The disadvantages are that solar panels can be expensive to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 9.3 years, but your solar payback period will vary based on your utility costs. The higher your typical power bill, the faster your solar panel system will recoup your installation costs.

When should I install solar panels?

You can install solar panels whenever it's convenient for you, but consider doing so in the winter when there's less demand. With fewer homeowners going solar, you could potentially see quicker installation times and more savings.
