E20-327 PANEL

Product catalog summary

Specifications:
The E-Series solar panels offer a high efficiency of 20.4%, making them ideal for rooftops with limited space or potential for future expansion. They are designed for high performance in various real-world conditions, including high temperatures, clouds, and low light.

Maxeon™ Solar Cells:
These cells are engineered for durability and performance, featuring a solid copper foundation that resists corrosion and cracking. The panels have been ranked #1 in the Fraunhofer durability test and maintain 100% power in the Atlas 25+ comprehensive PVDI Durability test.

Energy Production:
E-Series panels generate more energy per square meter, producing 36% more power per panel and 60% more energy per square meter over 25 years. They deliver 7-9% more energy per rated watt in the first year, increasing to 20% more over 25 years.

Operating Conditions and Mechanical Data:
The panels operate in temperatures ranging from -40°C to +85°C and can withstand wind loads of 2400 Pa and snow loads of 5400 Pa. They are resistant to impact from 25mm diameter hail at 23 m/s and have a Class A appearance rating.

Tests and Certifications:
The panels have passed standard tests such as IEC 61215, IEC 61730, and UL1703, and quality tests including ISO 9001:2008 and ISO 14001:2004. They are compliant with RoHS and OHSAS 18001:2007 standards and have passed ammonia and salt spray tests.

Electrical Data:
The E20-327 panel has a nominal power of 327 W with a power tolerance of +5/–0%. It features a rated voltage of 54.7 V and a rated current of 5.98 A. The maximum system voltage is 1000 V IEC & 600 V UL.

Warranty:
SunPower offers a combined power and product warranty, guaranteeing 95% power for the first 5 years with a degradation rate of -0.4% per year up to 25 years. The warranty includes panel replacement costs.
