Benefits of Solar Energy

Solar energy provides multiple advantages. Let's look at a few of them.

  • Better energy independence: Solar panel systems with battery storage systems operate through blackouts and emergencies, and you won't have to depend on the grid for your safety and well-being.
  • Lowered energy bills: You can avoid the premium cost of grid-tied power by producing some electricity at home. Plus, many states provide net metering which can allow you to sell your unused energy back for credits on your bill.
  • Reduced carbon footprint: Solar is one of the universe's most abundant clean energy sources, meaning you can minimize or conquer your home's dependence on "traditional" sources.

What Solar Incentives Are Available to Greenwich Homeowners?

How To Choose the Best Solar Company in Greenwich

Choosing a company is the first step toward an effective and valuable solar system. Consider each of these aspects in your service provider search.

Licensing and Training

In Connecticut, a journeyman who meet minimum experience requirements can take an exam to become a licensed solar PV or thermal contractor. Once they're licensed, they'll need to register with the state's Clean Energy Fund, so their customers can earn incentives. Solar providers can also earn accreditations from trade groups and standards organizations. The most respected ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Greenwich

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power and generally have the highest quality. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

You can also add electric car (EV) chargers and battery backup systems. These will increase your total installation cost, but they can boost your solar system's efficiency. Not every solar contractor includes these add-ons, so look for a provider that sells them if it's essential for you.

A majority of Greenwich homeowners select solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $18,750 to install, considering both materials and labor. You can see more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,204
Solar Polycrystalline$939
Thin-Film$549
Solar Battery$771
Solar Home EV Charger$2,890

Financing Solar Energy in Greenwich

Solar providers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar leases, power purchase agreements (PPAs), solar loans and cash payments. Most solar experts recommend paying cash or using a solar loan. Cash payments demand a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Much like a car or home loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to use your panels for a set monthly rate, while PPAs let you pay just for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We recommend working with a provider that offers multiple financing options. Speak with each salesperson about what's available, and get more than one estimate for the best odds of keeping within your budget.

The table below lists the average payback periods for different capacities of solar systems in Greenwich.

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, utilities and local governments may have their own rebates and financing plans that could reduce your total cost even more.

Solar System CapacityEstimated Payback period
1 kW1.9 years
2 kW3.8 years
5 kW9.4 years
10 kW18.9 years
