SunPower E20 Series Solar Panels

Product catalog summary

SunPower's High Efficiency Advantage
SunPower E20 solar panels are recognized for their high efficiency, reaching up to 20.1% panel efficiency and 22.5% cell efficiency. This is achieved through patented all-back-contact solar cell technology, which enhances both efficiency and reliability.

Maximum System Output
The panels are compatible with a wide range of inverters, allowing for optimized system output. This compatibility ensures that the highest efficiency panels can be paired with the most efficient inverters.

Reduced Installation Cost
Due to their high power output, fewer panels are required for installation, reducing both time and cost.

Reliable and Robust Design
SunPower's MaxeonTM cell technology and advanced module design contribute to the panels' reliability, making them a robust choice for solar energy systems.

Electrical Data
Under standard test conditions (STC), the panels have a peak power of 327 W, a rated voltage of 54.7 V, and a rated current of 5.98 A. The maximum system voltage is 600 V, and the panels have a temperature coefficient of -0.38%/K for power.

Tested Operating Conditions
The panels can operate in temperatures ranging from -40°F to +185°F (-40°C to +85°C) and withstand a maximum load of 113 psf (550 kg/m²) for snow and 50 psf (245 kg/m²) for wind. They are also impact-resistant to hail at 51 mph (23 m/s).

Warranties and Certifications
SunPower offers a 25-year limited power warranty and a 10-year limited product warranty. The panels are certified to UL 1703 standards and have a Class C fire rating.

Mechanical Data
The panels consist of 96 SunPower MaxeonTM cells, with high transmission tempered glass and an anti-reflective coating. The junction box is IP-65 rated, and the frame is made of anodized aluminum alloy type 6063.

Dimensions
The panels measure 1559 mm x 1046 mm and weigh 41.0 lbs (18.6 kg).
