LONGI 445W LR4-72HPH-35 is a 144 cell module with high efficiency and low LID mono PERC cells. Half-cut Multi Busbar Technology improves performance and boosts production of the solar panel. .
LONGI 445W LR4-72HPH-35performs at 20.5% efficiency, ensuring excellent energy yields. It is achieved due to the advanced technologies, such as M6 Gallium-doped wafers and 9-busbar half-cut cell technology. .
Slow power degradation is achieved due to Low LID Mono PERC technology. First year the panel degrades <2%, and 0.55% over the next 24 years. .
All LONGI panels undergo a number of stringent quality control tests. LONGI 445W LR4-72HPH-35is designed to withstand front side maximum static loading of 5400Pa and rare side maximum static loading of 2400Pa. .
The module’s 35 mm frame design provides easy mounting and ensures robust mechanical strength, which makes LONGI 445W LR4.
[pdf] Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick. Thi. This technology is highly flexible, durable, lightweight, and has excellent indoor and low-light performance. Thin-film modules are made by depositing a-Si onto a flexible polyimide substrate using proprietary roll to roll vacuum deposition and monolithic interconnect systems.
[pdf] The number of solar modules shipped from China to Africa increased by 60% in the 12 months to June 2025, according to new analysis from Ember. The think tank recorded 15 GW of Chinese PV imports for the period, up from 9.3 GW the previous year.
