A major step forward for integrated solar and energy storage in Malaysia
JS Solar Holding Berhad is pleased to announce that its wholly owned subsidiary, JS Solar Holdiong Berhad, has accepted a Letter of Acceptance from GSPARX Sdn Bhd for an engineering, procurement, construction and commissioning (EPCC) contract at AEON Mall Seremban 2.
Valued at RM18.05 million, the project combines:
- A 4,652.5 kWp building-integrated photovoltaic (BIPV) and rooftop solar PV system; and
- A 3,856 kWh battery energy storage system (BESS), equivalent to approximately 3.856 MWh of energy storage capacity.
The full EPCC scope covers the supply, installation, testing and commissioning of both systems. The six-month project period is scheduled to run from 19 August 2026 to 19 February 2027.
This award marks another important milestone for JS Solar as the company expands beyond solar generation into integrated solar-plus-storage solutions for Malaysia’s commercial and industrial sector.
Shares of JS Solar Holding Berhad were trading at 20 sen on Tuesday, 18 August 2026, up 1.5 sen or approximately 8.1% from Monday’s closing price of 18.5 sen. Based on 325 million outstanding shares, the company’s market capitalisation stood at approximately RM65 million.
Why the 3,856 kWh BESS is a key part of the project
Solar panels generate electricity when sunlight is available, but a facility’s energy demand does not always follow the same pattern. A battery energy storage system helps bridge this gap by storing electricity and making it available for use according to the system’s configured operating strategy.
For large commercial facilities, BESS can be designed to support several important energy objectives:
1. Better use of solar energy
A BESS can store surplus solar generation for later use, allowing a facility to make better use of the clean energy produced on site. This helps align solar generation with the building’s actual consumption pattern.
2. Smarter Energy Monitoring System
When integrated with an appropriate energy management and control system, a battery can charge and discharge at selected times to optimise how electricity is generated, stored and consumed.
3. Peak-demand management
Depending on the final design and operating strategy, a commercial BESS can help reduce short-duration demand peaks by supplying stored energy when electricity consumption rises. This capability is commonly known as peak shaving.
4. Greater energy flexibility
Battery storage gives commercial facilities more flexibility in managing changing demand profiles, operating schedules and future energy requirements. It also provides a platform for more advanced energy-management strategies as Malaysia’s electricity market continues to evolve.
The precise operating functions and performance of the AEON Mall Seremban 2 BESS will be determined by the approved system design, control strategy and site requirements.
From solar generation to an integrated energy solution
The combination of 4,652.5 kWp of solar PV capacity and 3,856 kWh of battery storage demonstrates an important shift in commercial renewable-energy projects.
Solar PV remains central to producing clean electricity, while BESS adds the ability to manage when that energy is used. Together, these technologies can form a more responsive and efficient energy solution than solar generation alone.
The project also includes BIPV and conventional rooftop solar elements. BIPV integrates photovoltaic technology into parts of a building’s structure or envelope, while rooftop PV uses available roof space to generate renewable electricity. Bringing these solar applications together with battery storage requires coordinated engineering across electrical design, equipment selection, protection systems, controls, installation, testing and commissioning.
Full EPCC capability for solar-plus-storage projects
As the appointed EPCC contractor, JS Solar will manage the project through the key stages of delivery:
- Engineering: Developing an integrated system design suited to the site’s technical and operational requirements.
- Procurement: Coordinating the equipment and components required for the solar PV and BESS installations.
- Construction: Managing safe, efficient installation at an operating commercial property.
- Commissioning: Testing and validating system performance before handover.
This end-to-end responsibility is essential for solar-plus-storage projects, where the PV array, battery, power conversion equipment, protection architecture and control platform must function as one coordinated system.
Advancing commercial BESS adoption in Malaysia
As businesses pursue greater energy efficiency, decarbonisation and control over electricity costs, battery storage is becoming an increasingly important part of the clean-energy conversation.
The AEON Mall Seremban 2 project reflects JS Solar’s continued commitment to delivering practical, scalable renewable-energy infrastructure. It also strengthens the company’s experience in integrating solar PV with BESS for large commercial applications.
Subject to unforeseen circumstances, the contract is expected to contribute positively to JS Solar Holding Berhad’s earnings, earnings per share and net assets for the financial year ending 31 March 2027, as stated in the company’s announcement.
