Highly durable and weather-resistant portable solar power generators designed to secure charging capability under high humidity and monsoon conditions.
Bridging grid infrastructure gaps in Dhaka, Chittagong, Sylhet, and remote off-grid communities through high-durability solar integration.
Bangladesh is experiencing rapid economic growth, yet it continues to face structural energy issues, grid instability, and load shedding in rural and suburban regions. In areas like the Sundarbans, the Chittagong Hill Tracts, and the marshy delta plains (haors), establishing centralized electrical grids is not just technically demanding but economically unfeasible. Field workers, agricultural inspectors, NGO officials, and climate researchers operating in these regions require consistent, reliable energy sources. Solar backpacks have transformed from recreational outdoor products into essential, work-ready tools for mobile technicians, students, disaster relief organizations, and clean-energy advocates.
In addition, Bangladesh is at the forefront of global climate change vulnerability. Extreme weather events, monsoons, and floods frequently disable regional microgrids. Under disaster conditions, maintaining communications is vital. A solar-powered backpack represents an autonomous lifesaver, ensuring that phones, GPS equipment, water purification accessories, and emergency lighting systems remain powered even when local infrastructure fails completely.
Operating a solar PV cell in Bangladesh requires superior engineering compared to standard dry climates. The combination of intense summer heat (exceeding 40°C in inland regions) and high atmospheric humidity leads to traditional PET laminated solar cells degrading or yellowing at accelerated rates. At Anhui Aryam Energy Co., Ltd., our solar integration utilizes ETFE (Ethylene Tetrafluoroethylene) fluoropolymer encapsulation. This advanced coating is highly resistant to salt spray corrosion in coastal districts like Cox's Bazar and remains chemically stable at extreme temperatures, ensuring a prolonged operational lifecycle for the solar panel array.
High-efficiency SunPower monocrystalline cells paired with smart MPPT voltage regulators for secure device protection.
Our backpacks feature lightweight, flexible monocrystalline silicon cells offering solar-to-electric conversion efficiencies of up to 24%. Unlike cheap multi-crystalline variants that underperform under cloudy conditions, our technology utilizes back-contact cell configurations to maximize light capture. This guarantees consistent power generation even during overcast monsoon days in Dhaka.

For large-scale buyers, NGOs, governmental agencies, and corporate clients in Bangladesh, Anhui Aryam Energy Co., Ltd. offers comprehensive OEM and ODM support. We understand that field researchers require different specifications than urban commuters or logistics field agents.
Every single batch of solar backpacks exported to Chittagong Port goes through strict quality management validation:
Aligning with the Mujib Climate Prosperity Plan and local green energy frameworks.
The Government of Bangladesh has outlined plans to increase renewable energy generation to 40% of its overall energy mix by 2041. By adopting solar-integrated gear for government field surveyors, healthcare professionals, and agricultural researchers, public sectors directly support carbon footprint reduction. These portable units mitigate dependence on fuel-based generators and single-use dry batteries, which frequently end up in rivers, causing heavy metal pollution.
With digital learning expanding across remote districts, students in rural schools are increasingly utilizing digital tablets for their studies. In areas where home electricity supply is inconsistent, a student equipped with a high-capacity solar backpack can charge their device on their walk to school. This bridges the digital divide and provides clean illumination in households that rely on hazardous kerosene lamps for evening study.
