Home

Conventional Solar

Conventional solar systems are typically built with components from different brands and manufacturers, with multiple warranties for different parts.

The SunPower Equinox® solar + storage system

The entire SunPower Equinox® solar + storage system, from solar cell to software, is designed and engineered to work better together. The system generates more power in less space with fewer visible parts, stores unused energy, and delivers it in an elegant, minimal design.

Racking: Conventional Solar

Most conventional solar racking hardware systems (the frame that holds the panels in place) are built to fit all panel brands, compromising on aesthetics.

Racking: SunPower Solar

SunPower’s proprietary InvisiMount® racking system sits beneath the panels, providing a custom-fit that lays flat on your roof and is barely visible from below. The accessories are designed to work together, securing your investment for the life of the system, providing a clean aesthetic and peace of mind.

Panel: Conventional Solar

When roof space is limited, so is system power. Most conventional solar systems resort to asymmetrical installations that span multiple sides of the roof to meet the home’s energy needs.

Panel: SunPower Solar

The SunPower Equinox® system provides the highest efficiency solar available on the market1 to your rooftop, producing energy to run your home beautifully with fewer panels, which can result in a compact, symmetrical installation. SunPower® panels are available in black or white sheet options.

Storage: Conventional Solar

Other storage systems are complex and messy, with multiple boxes and configurations.

Storage: SunPower Solar

SunPower® Equinox Storage combines the sleek and minimalist design that customers expect from SunPower. Equinox Storage uses battery technology tested for long-term reliability and durability, backed by a 10-year warranty to give you peace of mind.

Consumption Monitoring: SunPower Solar

The SunPower Equinox® solar + storage system comes with EnergyLink® software that helps you track how much energy you’re producing and using.3 Check in anytime from your smartphone, tablet or desktop to see your daily energy profile,4 estimated savings, manage your storage and energy use, and see the positive impact you’re having on the environment.
