ONESUN Global Joint Venture Program: Turnkey Solar & Battery Factory Solutions for PV Manufacturers
As the global solar industry continues to expand beyond China, a new wave of photovoltaic (PV) manufacturing hubs is emerging across India, Turkey, Vietnam, Malaysia, Thailand, Brazil, and Egypt. These countries have already developed scalable solar module production capabilities with semi-automated or fully automated assembly lines. However, as competition intensifies and profit margins tighten, local manufacturers are now seeking new ways to upgrade capacity, reduce costs, and increase revenue streams.
ONESUN, a leading provider of solar energy storage solutions and lithium battery manufacturing systems, is actively seeking global partners to establish localized joint venture factories. Through flexible cooperation models and turnkey solutions, ONESUN empowers PV manufacturers to upgrade their production lines and expand into high-growth sectors such as energy storage.
Why Global PV Manufacturers Need to Upgrade Now ？
Most existing solar panel manufacturers already have stable production processes and established distribution channels. However, relying solely on PV module sales is no longer enough to maintain long-term competitiveness. Market trends clearly show that integrating energy storage systems (ESS) with solar products significantly increases customer value, system efficiency, and overall profitability.
By upgrading automated production lines and adding battery storage manufacturing capabilities, companies can:
Improve production efficiency and product quality
Reduce labor costs through automation
Expand product portfolios into high-margin ESS markets
Increase average order value and customer retention
Strengthen competitiveness in both local and export markets
