The Cost and Benefits of Solar in Cambridge

For many readers, the decision of which solar installer to choose depends on total costs. Some important factors that affect how much it will cost to install solar panels on your home and how much it could save you over time include:

  • Average daily sunlight: Since Cambridge gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 26% of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $23,000 over 20 years on your energy bills.
  • Electricity consumption: The average household in Cambridge doesn't use much energy, and as a result may not see as many savings on their power bills.
  • The model of solar panel system you can buy: This is dependent on your income and budget.

There are lots of great benefits of solar despite the upfront cost of installation. It can help the planet and your finances. Additionally, it can raise the value of your home, giving you even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in Cambridge

If you're considering adding solar panels to your home, one of the principal reasons why may be to reduce your carbon dioxide emissions. Something many people might have in mind is how much can they really help preserve the environment by switching to solar power anyway? For homeowners and business owners who want to do their part for the planet, going solar is a straightforward choice, especially since Cambridge produces a fair amount of carbon dioxide emissions from its energy generation. Even though making solar panels releases carbon dioxide emissions, the panels make up for it by greatly decreasing the amount of CO2 you would have produced if you still used traditional energy. In Cambridge, you can reduce your carbon footprint by 40 pounds a year with solar panels. If you want to do what you can for the environment, you'll no doubt get that there are many good things about adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Cambridge, MA Solar Company Rankings FAQs

Which solar company is the best in Cambridge?

In Cambridge, Alternative Energy Store, Inc. is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're planning on installing solar panels on your roof.

What are the best and worst things about solar power?

A few of the biggest pros are that it lowers your power bills, it's eco-friendly, and it can provide a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels can be an eyesore.

How long does it take to see a return on your investment after buying solar panels?

Solar panels usually pay for themselves in about 8.8 years, but your solar payback period will vary based on your utility costs. The more your typical energy bill, the quicker your solar panel system will recoup your installation costs.

When should I put up solar panels?

Although summer is the most common time people install solar panels, the best time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
