Back Contact (BC) Solar Technology Development White Paper At the key node of intergenerational transition of global Photovoltaic (PV) technology, the back contact (BC) cell technology is leading the
This success is not an isolated case. The adoption of this technology is expanding globally, with LONGi set to supply 1.1 GW of its Hi-MO 9 BC modules for the massive 1.5 GW PV4
Chinese module manufacturer LONGI has launched a new back-contact (BC) lightweight module for commercial and industrial (C&I) rooftop applications. The Hi-MO X10 Guardian Light
LONGi''s technological and manufacturing leadership in solar wafers, cells and modules underscores our commitment to helping accelerate the clean energy transition.
By the second half of 2025, we''ll achieve 50GW proprietary BC cell capacity plus about 10GW through partnerships, totaling 60GW—making this the world''s most advanced mass-produced
LONGi launched its mono-PERC modules in 2016, featuring integrated PERC technology on monocrystalline silicon and low light degradation, and its cell efficiency has increased from 21% to
The BC structure also supports line interconnections rather than Z-shaped connections, reducing stress along the cell rim from 50 MPa to 26 MPa, thereby enhancing structural integrity.
From revolutionizing the industry by mainstreaming monocrystalline technology over polysilicon, to pioneering perovskite and BC solar cell research, the company has built an end-to-end
Depending on the materials used in the manufacturing process of the panels, PV technologies can be broadly classified into three generations: crystalline silicon (c-Si), thin-film
PEES Power Systems is a leading provider of advanced energy solutions in South Africa and Africa. We specialize in microgrid systems, solar photovoltaic (PV) power generation, BESS (battery energy storage systems), grid‑tied / hybrid / off‑grid inverters, PCS power conversion systems, EMS energy management systems, BMS battery management systems, lithium‑ion & LiFePO4 batteries, and modular energy storage systems. Our portfolio also includes energy storage containers, energy storage cabinets, containerised power stations, off‑grid power supply systems, backup emergency power, clean energy solutions, new energy storage systems, and green power systems. We offer battery cabinets with integrated BMS, outdoor all‑in‑one storage cabinets, commercial & industrial storage, communication battery cabinets, server racks, and transformer capacity expansion services. Whether you need a small off‑grid system or a zero‑carbon factory solution, our products deliver reliability and performance.
Our modular energy storage solutions range from 20ft/40ft mobile containers to outdoor all‑in‑one energy storage cabinets. We are a leading manufacturer of battery cabinets with BMS, offering communication battery cabinets for telecom, server racks for data centers, and energy storage battery BMS systems. We utilize lithium‑ion energy storage batteries and LiFePO4 batteries for optimal safety and lifecycle. Our stackable design allows flexible capacity expansion, while our grid‑forming technology ensures stable microgrid operation. Whether for distributed PV systems, off‑grid power supply, backup emergency power, or large zero‑carbon parks, our products feature advanced thermal management, PCS and EMS integration, and compliance with South African and international standards. We also provide professional energy storage system installation and after‑sales support, and we help clients navigate energy storage subsidies where applicable.
