JA Solar has strengthened its presence in Latin America by reaching a 22%–24% market share in Chile, positioning itself as one of the country’s leading photovoltaic (PV) module suppliers. Building on this momentum, the company is now moving decisively into the energy storage segment with the launch of JA Energy Storage, its new business unit focused on integrated PV and battery solutions.
“At JA Solar, we currently hold between 22% and 24% of the Chilean market this year, which places us among the top manufacturers by market share,” said Marcos Donzino, Head of Sales South LATAM, during Future Energy Summit Chile.
He added that the move into storage is a natural evolution of the company’s strategy. “As a solar panel manufacturer, entering energy storage is almost a natural step. A power system with high renewable penetration inevitably requires storage to ensure reliability and economic viability.”
JA Energy Storage was officially launched to deliver fully integrated generation and storage solutions under a single brand, reducing both technical and financial friction in renewable project development.
The company recently unveiled its PV + BESS solution, which combines TOPCon photovoltaic modules with containerized battery energy storage systems (BESS). The portfolio includes:
-
Utility-scale systems with capacities of 5 MWh per unit
-
Commercial and industrial (C&I) solutions tailored to local market needs
JA Solar projects annual production of 30 GWh, supported by strategic partnerships and equity stakes in several battery cell suppliers, strengthening supply chain security and scalability.
According to the company, energy storage is no longer a future promise but a critical component for achieving project profitability in renewable energy markets with high solar and wind penetration.
“At a sector level, I see this more as a market-driven dynamic. Everyone needs to become more efficient in order to deliver bankable and profitable projects,” Donzino explained.
Battery storage also provides a cost-efficient technical solution to transmission bottlenecks, enabling short- and medium-term alternatives that are faster to deploy than new grid infrastructure. Applications such as peak shaving, grid support and ancillary services open additional revenue streams and investment opportunities.
Regulatory clarity remains critical
JA Solar expects competition in the storage segment to intensify, driving cost reductions and efficiency gains, similar to the evolution experienced in the solar PV market over the past decade.
However, Donzino stressed that this progress must be supported by clear and consistent regulatory frameworks, avoiding legal ambiguities that could undermine investor confidence and delay energy transition objectives.
With this strategic expansion, JA Solar aims to position itself as a regional leader in integrated solar PV and energy storage solutions across Latin America, leveraging its technological expertise and commercial scale to enable more efficient, profitable and financeable renewable energy projects.
