ONESUN Seeks Bangladesh Partners 2026: Joint Venture LiFePO4 Solar Battery & BESS Factory

ONESUN Partners with Bangladeshi Allies to Build a New Future for Solar Energy Storage

By 2026, as global green energy transformation accelerates, ONESUN—China’s leading solar energy storage solutions and lithium iron phosphate (LiFePO4) battery manufacturer—is actively seeking high-quality local partners in Bangladesh to jointly invest in and establish a photovoltaic (PV) energy storage factory. This strategic initiative aims to deeply integrate ONESUN’s globally leading technology with Bangladesh’s local resource advantages, driving the development of the country’s new energy industry.

The Government of Bangladesh places high importance on the development of solar energy storage and green energy. The Renewable Energy Policy 2025, released in 2025, sets ambitious targets: by 2030, 20% of electricity (approximately 6,145 MW) should come from renewable sources, rising to 30% (about 17,470 MW) by 2041. The policy also includes a 10,000 MW solar power target, along with a 10-year corporate income tax exemption for renewable energy producers, followed by a partial exemption for the next five years. It encourages battery energy storage system (BESS) integration, rooftop solar adoption, and public-private partnerships.

Additionally, the government promotes the Sustainable and Renewable Energy Development Authority (SREDA) to implement renewable energy purchase obligations, reduce import tariffs, support local manufacturing, and attract foreign investment through Commercial Power Purchase Agreements (CPPA). These favorable policies create an ideal environment for foreign joint ventures, significantly reducing investment risks and enhancing project returns.

Founded in 2014 and headquartered in Shenzhen, ONESUN operates battery and inverter factories, offering vertically integrated solutions that include PV modules, energy storage batteries, and inverters. The company specializes in providing efficient and safe solar energy storage systems. ONESUN uses top-tier A-grade LiFePO4 cells and incorporates an automotive-grade Battery Management System (BMS) developed by former BYD engineers, ensuring stable performance in high-temperature and high-vibration environments. Its products boast a cycle life exceeding 6,000 times and a design life of over 10 years. With exports to over 70 countries, ONESUN is trusted by B2B customers worldwide.

ONESUN’s product portfolio is diverse and tailored to meet Bangladesh’s market demands:

• Telecom base station batteries utilize high-stability LiFePO4 technology, providing reliable backup power for communications, power grids, and emergency systems.
• Integrated solar energy systems combine power generation, storage, and inversion in a single design, simplifying installation for households and small businesses.
• Residential and industrial PV energy storage systems (BESS) support modular expansion, making them ideal for factories, hospitals, and public facilities to achieve peak shaving and backup power.
• The PAYGO series introduces an innovative prepaid model, lowering the initial investment barrier and promoting solar energy adoption in rural and remote areas.

These products effectively address Bangladesh’s electricity shortages and peak demand challenges, helping users reduce energy costs and enhance energy independence.

Why Choose ONESUN?

As a globally recognized battery brand manufacturer, ONESUN specializes in serving B2B customers, offering optimal OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) battery customization solutions. The company rapidly develops diverse product formats, including wall-mounted, high-voltage stackable, and cabinet-style designs. Additionally, ONESUN provides SKD (Semi-Knocked Down) and CKD (Completely Knocked Down) localized assembly solutions, enabling partners to establish factories quickly, reduce tariffs and logistics costs, and achieve "technology + manufacturing" localization. With a strong supply chain integration capability, vertical integration production advantages, and global project delivery experience (over 3 GW of successful cases), ONESUN ensures high cost-performance ratios, reliability, and fast delivery. Partners can leverage ONESUN’s brand and technology to rapidly expand into local and South Asian markets, sharing the benefits of the green energy revolution.

Bangladesh enjoys abundant solar resources (solar irradiance of approximately 5 kWh/m²/day) and an annual electricity demand growth rate of 7%, with peak demand expected to exceed 25,000 MW. The ONESUN joint factory project will introduce advanced LiFePO4 BESS technology, supporting large-scale solar grid integration, reducing reliance on expensive diesel generators, and promoting energy security and carbon reduction. This collaboration will create jobs, drive local industrial upgrading, and inject strong momentum into Bangladesh’s green transition.

ONESUN invites visionary local partners in Bangladesh to join hands in writing a new chapter for the photovoltaic energy storage industry. Choosing ONESUN means choosing reliable technology, flexible cooperation models, and a sustainable future.
