How To Choose the Best Solar Company in Stamford

The more thorough your company research is, the better your solar panels will ultimately operate. Make your choice based on the following crucial aspects.

Licensing and Training

In Connecticut, a professional meeting minimum experience requirements can take an exam to become a licensed solar PV or thermal contractor. Once they're licensed, they'll need to sign up with the state's Clean Energy Fund, so their customers can earn incentives. You should also visit a company's website to learn about its private accreditations. Two of the most respected are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Stamford

Your solar modules' type will influence how much electricity you can generate. Monocrystalline panels cost the most but perform the best. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

You can also add electric car (EV) chargers and battery backup systems. These will increase your total project price, but they can enhance your solar system's efficiency. Not all solar companies offer these extras, so look for a contractor that sells them if it's a priority for you.

Generally speaking, it will cost about $18,750 for a five-kilowatt solar array in Stamford. This table displays more specific pricing information for different solar panel types and system components in your area.

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 Stamford

Choosing the correct financing option will impact your overall solar system cost and potential savings. Common payment options include cash payments, leases, loans, and power purchase agreements. Though it involves a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the second most effective option. As with a car or home loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to pay a monthly fee to rent your panels, while a power purchase agreement lets you pay a variable rate based on only the energy you use. We generally advise against these options since you won't own your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. Look for providers that offer two or more payment plans to find the right fit for your budget.

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

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

Solar System Capacity Estimated Payback period
1 kW 1.9 years
2 kW 3.8 years
5 kW 9.4 years
10 kW 18.9 years

Frequently Asked Questions About Solar in Stamford

How much money could I save by going solar in Stamford?

Most Stamford homeowners spend about $1,844 on energy each year. Your costs could drop by $1,207.35 for each kilowatt you generate after you pay off a solar array.

Is solar energy readily available in Stamford?

Yes, solar energy is reaching new heights in Stamford. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 2234 workers and counting.

Will a solar PV system improve my Stamford home value?

Yes, solar panels will increase your property value. According to the National Renewable Energy Laboratory, for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How long will an average solar system last?

Modern solar panels are designed for durability. The average panel lasts at least 25 years. Cheaper panels tend to last shorter than top-tier models.

What maintenance do my solar panels need, and how often do they need it?

Solar panels don't need much maintenance to keep working properly. All you'll need to do is inspect and clean the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to assist in your system's care.

What's the average solar system size in Stamford?

The average Stamford solar system size is 4.5 kilowatts (kW). However, your final system size depends on your family's electricity usage. Your roof size, surrounding shading, and panel model could also impact your final result. A professional solar installer will consider these factors and determine the right array size for your home.

What's the difference between a PPA and a solar lease?

After you sign a power purchase agreement, your solar company will not charge to install or maintain your new panel array. Instead, you'll pay them only for the electricity you generate. Typically, PPAs last for 10–25 years or until you "buy out" of the contract.

If you choose a lease, you'll make set payments each month.

With both leases and PPAs, you don't own your panels and lose eligibility for some incentives. Further, you'll have to "buy out" or transfer the contract if you sell your home during the term.
