The Cost and Benefits of Solar in Greenwich

When deciding on a solar company, most homeowners or business owners wonder about the costs above all. The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • Your income and budget: This shapes what type of solar panels you can afford.
  • How much energy your household consumes: Homes that consume lots of electricity each month may call for more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state may also have incentives and rebates that you can take advantage of. Additionally, you can save about $24,000 over 20 years on your utility bills, without incentives.
  • Average daily sunlight: Since Greenwich gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much you can save on your energy bills.

There are several wonderful benefits of solar despite the upfront cost of installation. It can help the Earth and your wallet. Plus, it can raise the value of your home, resulting in even more benefits if you choose to sell your home later.

Solar Incentives in Greenwich

In order to increase the adoption of solar power, federal and local governments — and even some utility companies — offer incentives to help make going solar more economically viable and accessible. These incentives usually consist of cash rebates, tax benefits and/or solar renewable energy credits. They can reduce the cost you pay for installing solar panels by 30%, upwards of 50% depending on your location. Our article on solar incentives has more detailed information on the incentives you can benefit from in Greenwich.

Environmental Impact of Switching to Solar in Greenwich

There are many reasons to trade traditional energy for solar power, like saving on electricity bills and helping to reduce your carbon footprint. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Greenwich, though. Everyone can help the environment by switching to solar energy, but homes that use a lot of energy will have a bigger impact. Since solar panels don't release CO2 emissions into the atmosphere when creating electricity, they're a good swap for traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 40 pounds each year. If you want to do your part for the environment, you'll likely get that there are many advantages to adopting solar power other than just saving money on electricity. You can also help protect the environment, which some would argue is invaluable.
