How To Choose the Best Solar Company in Greenwich

The more comprehensive your company investigation is, the better your solar installation will ultimately function. Make your choice based on the following crucial aspects.

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 companies can also obtain accreditations from standards organizations and trade groups. The most prestigious 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

The kind of solar panels you choose determines how much energy you can generate. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

If you need to charge an electric car or use your solar power in inclement weather, you can pay extra for add-ons. By selecting the right components, you can make your panel array more effective and user-friendly. Not all solar providers offer these add-ons, so look for a provider that installs them if it's important for you.

You can expect to pay about $18,750 on average for a five-kilowatt solar energy system in Greenwich. Use the table in this section to get an idea of the amount Greenwich solar companies might quote for your specific system.

Solar Panel Cost Average 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 contractors use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are cash payments, power purchase agreements (PPAs), solar loans and solar leases. We recommend paying with cash or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar incentives to reduce your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still benefiting from energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases allow you to rent your panels for a set monthly rate, while PPAs let you pay just for the energy you use, akin to an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We recommend working with a company that offers multiple financing options. Speak with each salesperson about what's available, and acquire more than one estimate for the best odds of keeping within your financial plan.

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

A 26% federal tax credit applies to recently-purchased solar equipment purchased through 2032. Additional incentives may be available through local governments, usually in the form of rebates and special financing programs.

1 kW 1.9 years
2 kW 3.8 years

Is solar energy widely available in Greenwich?

Yes, solar energy is on the rise in Greenwich. Some homes already use solar power on-site or through utility grids, and they're fortified by a state solar economy with 2234 workers and counting.

What if I live in a heavily-wooded or rainy

Even if your property has high tree cover, you could still take advantage of solar energy. Your technician will enhance your system's performance by choosing the proper site for panels, positioning them to capture the most sunlight throughout the year, cleaning them regularly, and installing a battery backup system. This way, you can store solar power and use it as necessary.

How can I check my property's solar viability?

To determine your home's solar readiness, there's no substitute for a comprehensive estimate from a local solar provider. However, you can use the PVWatts tool for a simple solar viability estimate based on public data, including system size, tree cover, local weather and topography, and panel efficiency.

How do I care for my new solar system?

To preserve your solar system's performance, inspections and cleanings every six months are usually sufficient. In dusty or dry seasons, your panels might need cleanings every few months. Your technician can recommend a maintenance schedule. Its team could also tackle the cleaning for you.

How can I boost my solar panels' performance?

To enhance your solar system's performance, you can use the following steps:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances
