The Rajshahi Division, historically referred to as the agricultural granary of Bangladesh, faces complex structural difficulties within its cold-chain infrastructure. Accounting for more than 60% of the country’s high-value mango yields (primarily from Chapainawabganj, Naogaon, and Rajshahi districts) alongside significant tomato, potato, and freshwater aquaculture yields, the region suffers from severe post-harvest decay rates ranging between 25% and 38%. This substantial loss is directly tied to the unreliability of the local electrical distribution infrastructure.
During the peak harvest window from April to August, temperatures in Rajshahi routinely exceed 40°C. During these exact periods, the electrical distribution network experiences chronic voltage drops and extended load-shedding schedules. Standard grid-connected cold storage depots struggle to keep consistent interior temperatures, resulting in rapid produce deterioration. The traditional alternative, diesel-powered standby generators, poses serious economic difficulties due to rising fuel costs and transportation bottlenecks in rural farming areas.
"The integration of Walk-on Solar Panels (BIPV) with high-efficiency walk-in thermal enclosures represents the next step for decentralized, resilient cold-chain management. By converting the structural roofs of containerized cold rooms into high-yield, impact-resistant solar generation surfaces, growers can establish self-sustaining, zero-emission cold storage directly at the farm gate."
Decoupling clean energy generation from spatial footprint limits. Our industrial walk-on photovoltaic panels serve a dual purpose: durable structural weather barriers and high-density power generation modules.
Traditional roof-mounted solar installations are vulnerable to mechanical damage, wind uplift, and the build-up of dirt during the dry seasons in Rajshahi. Shanxi Sypower Solar’s Walk-on BIPV (Building-Integrated Photovoltaics) systems resolve these operational challenges through a series of key engineering advancements:
Constructed with dual 3.2mm tempered, high-transmission glass sheets. This structural composition allows the modules to withstand direct static load capacities up to 5400 Pa, allowing technicians to walk directly on the array for cleaning and routine maintenance without causing internal micro-cracks in the silicon cells.
Features a specialized acid-etched, anti-slip surface pattern that meets the DIN 51130 R11 slip-resistance standard. This guarantees maintenance personnel can safely inspect and clean the panels, even during heavy monsoon downpours common in the Rajshahi district.
Utilizes ultra-high efficiency N-Type Tunnel Oxide Passivated Contact (TOPCon) solar cells. These cells deliver exceptional performance in low-light environments and offer an improved temperature coefficient (-0.30%/°C), ensuring optimal power output during hot summer days in Rajshahi.
Additionally, Sypower’s walk-on panels are designed with fully potted, low-profile junction boxes rated at IP68. The bypass diodes are strategically integrated to minimize power drops caused by partial shading, which often occurs from agricultural dust build-up or surrounding vegetation. The low profile of these boxes ensures they remain flush with the installation frame, preventing tripping hazards and protecting the electrical connections from mechanical stress.
As a global leader in BIPV production and customized solar power systems, Shanxi Sypower Solar Co., Ltd. leverages China’s highly integrated solar manufacturing ecosystem to deliver commercial-grade technology to the Rajshahi market. Our manufacturing facilities utilize fully automated assembly lines, high-precision laser slicing, and advanced EL (Electroluminescence) testing to ensure every panel is free of micro-cracks and material defects before shipment.
Our vertically integrated supply chain enables us to source raw silicon, tempered protective glass, and critical components at stable costs, insulating our international buyers from sudden price fluctuations. For projects in Bangladesh, this structural advantage translates to shortened lead times, reliable batch quality, and direct technical support from our factory engineering team.
We manage shipping and logistics logistics directly, routing deliveries through Chittagong and Mongla ports to ensure secure inland transit to installation sites throughout Rajshahi. Every shipment includes comprehensive documentation, installation drawings, and matching electrical component kits, minimizing installation challenges for local engineering teams.
Deploying solar infrastructure within the Rajshahi Division requires compliance with the technical standards established by the Sustainable and Renewable Energy Development Authority (SREDA) of Bangladesh. Sypower’s Walk-on BIPV panels and matching walk-in cold rooms conform to all national electrical codes and carry international certifications including NSF, CE, ETL, and UL. This ensures complete compliance when connecting to the local grid or operating in off-grid configuration.
