Solar Company Ranking Methodology

The Cost and Benefits of Solar in Greenwich
When picking a solar company, most homeowners or business owners care about the costs the most. There are several factors you should consider when trying to determine how much it will cost and how much you can save, such as:
- The kind of solar panel system you can buy: This depends on how much you're willing to invest upfront.
- How much you spend on energy: The typical household in Greenwich shells out around $620 a year on energy alone, so you could be looking at that much in savings.
- Electricity consumption: The average home in Greenwich doesn't use much energy, and consequently may not see as many savings on their power bills.
- Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state may also have incentives and rebates that you can use. Additionally, you can save about $13,000 over 20 years on your utility bills, before factoring in incentives.
There are many great benefits of solar in spite of the initial cost of installation. It can help the Earth and your finances. In addition, it can boost the value of your home, resulting in even more benefits if you decide to sell your home later.

Solar Incentives in Greenwich
Switching to solar power has many considerable benefits. Not only can it help protect the planet, but you can also save a good amount of money on your installation with various government incentives. Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much your solar project cost on your tax return, reducing the amount of taxes you owe that year. Plus, there may be some state and city incentives that can save you some extra money too. In our article on solar incentives, you can see the incentives you qualify for in your area.
Environmental Impact of Switching to Solar in Greenwich
Replacing nonrenewable energy with solar power is a profound way to do what you can for a greener future. Something many homeowners might have in mind is how much can they really help protect the environment by switching to solar power anyway? In a city like Greenwich where commute times can be very long, installing solar panels can help offset some of your carbon dioxide emissions from being on the road a lot. Since solar panels don't release carbon dioxide emissions into the atmosphere when generating electricity, they're a good trade for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 20 pounds each year. If you want to do what you can for the environment, you'll no doubt get that there are many advantages to adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.
