Solární panel Longi LR7-72HVH-640M, 640 Wp

Detailní popis produktu

The LONGi LR7-72HVH-640M is a high-performance module from the latest Hi-MO X10 series , designed for the highest performance in commercial and large-scale installations. The module achieves a massive 640 Wp peak power with 24.2% efficiency , allowing it to generate a massive amount of energy from the available space. This module features a 30mm frame . ----- BC-CELL (BACK CONTACT) TECHNOLOGY ----- The module utilizes groundbreaking back-contact cell technology ( BC-CELL / Back Contact ). Moving all electrical contacts to the back and eliminating front busbars increases light absorption and minimizes energy loss, while ensuring a seamless, clean front-end aesthetic. ----- EXTREME EFFICIENCY AND RESISTANCE ----- Advanced design using 3.2mm thick tempered glass effectively protects the cells against micro-cracks. The module is characterized by solid mechanical resistance, withstanding snow loads up to 5400Pa from the front and wind loads up to 2400Pa from the rear. According to the technical specifications, the panel has an IEC Class C fire resistance rating . ----- LOWER LOSSES AND DURABILITY ----- Thanks to the BC cell architecture, the module operates at a lower temperature , drastically reducing power drops during summer heat. A very low power temperature coefficient of just -0.260%/°C ensures stable power production even in full sunlight. ----- LINEAR POWER DEGRADATION WARRANTY ----- LONGi offers a 15-year product warranty and a 30-year linear power warranty . Degradation in the first year is below 1% , and in subsequent years only 0.35% per year . Thanks to such stable parameters, after 30 years of operation the module retains as much as 88.85% of its initial power .
