products DESCRIPTIONPRODUCTS
Solar Panel Performance
The LR4-72HBD-450M solar panels have a rated output of 455 Wp and an impressive efficiency of 20.9 %, making them an excellent choice for homeowners looking to harness the power of the sun and reduce their energy costs.
With a maximum system voltage of 1500 V and a temperature coefficient of -0.35 %/°C, these solar panels can perform optimally even in challenging weather conditions.
Solar Panels Thermal Ranges
The thermal performance of the LR4-72HBD-450M solar panels from LONGi ensures their reliability and efficiency across varying temperature conditions. These panels are designed to operate optimally within a wide operating temperature range of -40~85 °C. Additionally, the temperature coefficients of the panels, such as the Temperature Coefficient of Pmax (-0.35 %/°C), Voc (-0.284 %/°C), and Isc (0.05 %/°C), play a vital role in determining the panel performance under changing environmental conditions. The carefully engineered thermal attributes of these solar panels contribute to their long-lasting performance and make them an ideal choice for regions with diverse climate patterns
