SUNPOWER
Better Solar Panels
SUNPOWER Solar Panels, The most efficient home solar panels available

Highest Efficiency Solar Panels from SunPower

SunPower made it's name for offering the highest efficiency solar panels, better performance and top quality installations. It all translates to better solar panels, more savings, and happier customers.
And with nearly 40 years of dedicated solar experience, we're the only U.S.-based solar company that's been around longer than our 25-year warranty. 
Designed to work with SunPower Equinox® home energy system, SunPower’s high-quality standards ensure that the solar cell technology makes more energy from every drop of sunshine. Factor in the elegant styling and durability, it’s no wonder our company has been leading the industry the longest.

SUNPOWER Solar Panels -Better More Efficient Solar Panels

Photovoltaic modules, commonly known as solar panels, are a technology that captures solar power to transform it into sustainable energy.
SunPower offers multiple high-efficiency solar modules that are rigorously tested to ensure system reliability, performance, and savings. There are many options of solar panels options with varying aesthetics and wattages, but the main two types of solar technology are categorized as follows:

The Renewable Energy Project by TIER 1 Solar Solutions logo

Front-contact solar modules

Also known as "Passivated Emitter and Rear Contact" (PERC), are an advancement on conventional panels with an extra layer within in the back side, allowing some of the sun’s light to be reflected back into the solar cell.

Back-contact solar modules

Known as IBC technology, or “interdigitated back contact”, are highly durable due to a thick layer of tin-plated copper on the back that holds the cell together. Because they do not have contacts on the front of the panel, they provide higher performance due to higher use of the light spectrum.

 

SunPower solar works harder for you, every day

If you’re going solar, go all the way. SunPower Equinox home solar systems are designed to wake up earlier, work harder, and turn off later in the day. So you can make the most of abundant solar energy and the vast savings it brings.
SunPower Equinox systems generate more power in less space with fewer visible parts for a minimalist design.
And with mySunPower® monitoring you can track your solar output & performance from virtually anywhere, using our phone, tablet, and desktop applications.

Rigorously quality tested, the panels pair with storage and monitoring hardware so that you can track performance in real time with the mySunPower® app.
And, when installed using SunPower’s InvisiMount® mounting system, you’ll enjoy a streamlined appearance on your roof with fewer visible parts.

IBC vs PERC: What's the Best Type of Solar Panel
October 14, 2019

Solar manufacturers are always looking for new ways to make solar cells more efficient, so it's no wonder there are different types of solar panel technologies for customers to choose from, each offering varying levels of efficiency and reliability.
Cells known as "Passivated Emitter and Rear Contact," or PERC, are becoming more common. PERC solar cells have an extra layer on the back side that allows some of the sun's light to be reflected back into the cell. This layer gives the sun's rays a second chance to be absorbed and converted into energy, making PERC solar cells 6 to 12 percent more efficient than conventional solar panels.
While PERC solar panels are a step above other types of conventional panels, IBC – or "Interdigitated Back Contact" – panels go even further, with even better efficiency, energy yield and reliability.

Pros and cons of PERC and IBC solar cells
We offer our customers the choice between panels made of PERC or IBC cells, both of which have their pros and cons. Here's a brief rundown on each: 

PERC Pros

• Manufactured like conventional solar cells, which means they can be manufactured using existing equipment.

• Higher efficiency versus non-PERC panels means fewer panels are needed to produce the needed amount of electricity. 

PERC Cons

• Most PERC solar panels have metal strips running through them, which may not be the aesthetic some homeowner are looking for. 

IBC Pros

• Highest-efficiency solar panels available today, lowering installation costs and maximizing the amount of energy produced.*
• Greater efficiency means fewer panels needed, leaving room to add panels if you, for example, add an electric vehicle.
• Lower degradation rate than other panels. SunPower® M-Series panels have a degradation rate two to three times lower than conventional panels.* This means more power over the life of the system. 
• Better performance at higher temperatures and use of more of the light spectrum to create more energy, even early in the morning or late in the evening.
• Cell-level hotspot protection increases performance in shade.

IBC Cons

• These panels may have a higher up-front cost, though over time you'll see a higher return on your investment with a more efficient panel.
