SunPower Simplifies Solar Power

Solar power installations have grown exponentially over the past few years with a new homeowner going solar roughly every 90 seconds. Even still, the process of going solar can be confusing.

SunPower makes buying solar power easier with these simple tips, resources and FAQs.


A photovoltaic (PV) solar energy system is composed of solar panels, racking for mounting the panels on the roof, electrical wiring, and an inverter. From sunrise to sunset, the solar panels generate direct current electricity (DC) which is sent to the inverter. The inverter converts the DC into alternating current (AC), the type of electricity required for household use. (SunPower also offers AC solar panels which do not require a central inverter because they feature a microinverter that’s factory integrated into each panel.) The AC power is delivered directly to your home’s main electrical service panel for use by you and your family.

It’s important to minimize shading because solar panels operate at optimal output when their entire surface is fully exposed to direct sunlight. The system will still produce energy if it is shaded but its output will lessen.

SunPower will evaluate your particular situation and provide solar options for you. You can also read whether your home is a good candidate for solar to help when making the decision whether going solar is right for you.

Our systems are designed to have a useful life of 40 years or more.* For more information about solar panel durability and performance, check out this report on solar system useful life field tests performed on SunPower® systems vs. conventional panels.

Your current monthly energy use and the size of your system will determine your actual savings amount. And with little or no startup costs*, systems can start paying for themselves immediately. Savings will vary based on several factors, including system size, performance, your household’s average energy usage as well as any applicable solar credits, tax incentives, and current solar energy buyback (net metering) rates offered by your utility company. A detailed calculation of your potential return on investment (ROI) will be provided by SunPower during your solar evaluation. Get more information about what goes into calculating home solar panel system costs and other important solar energy questions to ask your installer.

Having a solar system typically adds value to your home.* Depending on where you live, there is often no increase in your property taxes.

SunPower has a wide variety of financing options, including some that don’t require you to pay any upfront costs if you qualify. The cost of your solar system depends on several factors, including your current energy usage, your available amount of unshaded roof space, your local utility’s net metering policy, and other factors. Learn more about how to calculate solar costs and how many solar panels you may need to power your home.

Despite the generalities you may hear in solar advertising, not all solar systems are created equal! Of all the solar panels on the market, SunPower panels have the highest efficiency* and convert the highest amount of sunlight into electricity. This means our solar panels generate more power than conventional panels within the same amount of space, and you’ll need fewer panels to produce the energy you need. You can maximize your available roof space to choose the best, unobstructed location for electricity production. Our world-record panel efficiency* means you’ll save more money over time by choosing SunPower panels. Check out why thousands of homeowners and businesses going solar chose SunPower as their solar company for high-efficiency solar technology solutions.

Local Incentives

Connecticut is ready to make big strides in solar. Thanks to its rebate program and other state incentives, Connecticut continues to pave the way for more and more of its millions of homeowners to go solar. Not only can we help you make sense of the most important ones—we can even help you funnel all those incentives into a low kWh rateso you can save without having to lift a finger.

Residential Solar Investment Program Up to $0.46 per watt (depending on system size) 1
Sales Tax Exemptions Solar System Sales Tax Exemption 2
Property Tax Exemptions Property Tax Exemption on Added Home Value from Solar System 3
Federal Solar Tax Credit (ITC) 30% of the total system cost 4

Thanks to CT Green Bank, if you buy a solar system for your home, you could qualify for the Residential Solar Investment Program rebate. You If you buy
a solar system that is up to 10kW (PTC) in size, you could get a rebate of up to $0.463 per Watt.  For systems greater than 10kW (PTC), you could receive a rebate of up $0.463 for the first 10 kW (PTC) and up to $0.40 per Watt for everything above 10 kW (PTC).

If you purchase a home solar system in Connecticut, you’ll also be exempt from the sales tax.2 That’s a pretty big deal, considering buying your solar system outright comes with a hefty price tag. You’ll also be exempt from paying additional property taxes, so that the value added to your home when you go solar is subtracted from the assessed value of your property.3

On top of all Connecticut’s solar tax credits, you’d also be eligible for the Federal Solar Tax Credit, or ITC, if you buy your own solar system outright. The tax credit amounts to 30% of the cost of purchasing your solar system, but only after deducting the value of your state rebates. However, ITC credits will begin stepping down from 30% at the end of 2019. The tax credit for systems in service after 12/31/19 will drop to 26%. After 12/31/20, it’ll drop even further to 22%.4 That’s why the time to go solar is now. But not to worry—we can help you maximize on all the solar savings available to you.

There’s lots of great solar savings to be found in Connecticut, but many of them are only available if you purchase your solar system. When you buy, it can take years for you to see a return on your investment, especially when you factor in the costs of maintenance and repairs. That’s why SunPower offers a revolutionary solar lease that passes the value of incentives over to you for as little as $0 down and a low kWh rate, plus free 24/7 system monitoring and maintenance.
