The Cost and Benefits of Solar in Greenwich

We understand that for lots of homeowners, the choice to invest in solar rests on installation costs. There are quite a few factors you should take into consideration when trying to determine the overall cost and how much you can save, such as:

  • The kind of solar panels you want to get: More efficient panels are more expensive, so that will influence your budget for your solar project.
  • Incentives: Something that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your utility bills, which can give you an average of $24,000 of savings over 20 years.
  • How much you spend on energy: The typical family in Greenwich spends around $1,100 a year on home energy use alone, so you could gain that much in savings.
  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.

Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, including the angle of your roof and incentives.

EcoWatch's Greenwich, CT Solar Company Rankings FAQs

Which solar power company is the best in Greenwich?

In Greenwich, Green House Solar is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your roof.

Are solar panels actually eco-friendly?

Making solar panels uses chemicals and produces toxic waste that can be harmful for the environment, which is the main negative thing about solar panels.

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

Solar panels typically pay for themselves in about 8.1 years, but your solar payback period will depend on your utility costs. The more your typical electricity bill, the faster your solar panel system will pay for itself.

When should I put up solar panels?

Although summer is the most popular time people install solar panels, the perfect 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.
