Jimmy Yong is the Chief Executive Officer of Solunar, leading the company’s strategic direction as a Battery Energy Storage System (BESS) system integrator and clean-energy technology partner for Malaysia and Southeast Asia.
Jimmy holds a background in Engineering, Electronics & Electrical from the University of Hertfordshire, a Master in Marketing from Louisiana State University, and an MBA from HELP University. This combination of engineering, marketing and business management gives him a strong multidisciplinary foundation to lead Solunar in both technical execution and commercial growth.
With his electrical and electronics engineering background, Jimmy understands the technical fundamentals behind power systems, solar integration, energy storage, inverters, PCS, EMS and electrical infrastructure. His business and marketing qualifications further strengthen his ability to position Solunar strategically, develop market opportunities, build partnerships and scale the company in the fast-growing energy storage sector.
As CEO, Jimmy is focused on positioning Solunar not merely as an equipment supplier, but as a trusted BESS integration partner for EPCC contractors, developers, asset owners and commercial and industrial clients. Under his leadership, Solunar supports clients in designing, integrating, commissioning, operating and maintaining safe, reliable and bankable energy storage solutions.
Solunar works with leading technology partners including BYD, GoodWe, EVE and other established energy-storage brands to deliver integrated solutions across commercial, industrial and utility-scale applications.
“Jimmy’s vision is to make BESS more practical, accessible and commercially viable for businesses and infrastructure owners — energy storage will become a critical infrastructure layer for Malaysia’s future.”
As Malaysia’s energy market evolves with rising maximum-demand charges, increasing solar adoption, grid constraints and the need for energy resilience, that future is arriving quickly.
Through Solunar, Jimmy is committed to helping businesses reduce electricity costs, manage maximum demand, strengthen energy resilience, optimise solar usage and accelerate the transition toward smarter clean-energy infrastructure.
Why Solunar Energy exists
Malaysia's solar market is becoming more competitive and margins are compressed. Customers now want more than panels — developers and asset owners want energy storage, and industrial clients want peak shaving, power expansion and energy resilience.
Solunar Energy exists to support this shift, giving EPCC companies, developers and asset owners access to better technologies, stronger integration support and long-term operational capability — without forcing them to build a full battery storage team in-house.
Solunar helps EPCC companies, solar developers and energy asset owners deliver bankable Solar + BESS projects without building full battery storage capability in-house.

What we do: three capabilities for the Solar + BESS market
Everything Solunar offers falls into three core capabilities that EPCC companies, developers and asset owners can draw on.
Technology Distribution
Supply of BESS technology, GoodWe inverters and batteries, and selected BYD and EVE battery solutions for suitable applications.
System Integration
Coordinating batteries, PCS, EMS, inverters, protection and monitoring into one safe, working storage system.
Long-Term O&M Support
Monitoring, maintenance planning and after-sales support for commercial and utility-scale ESS assets across their life.
Our services
Solunar's services span the full Solar + BESS technology stack:
- BESS technology supply
- GoodWe inverter and battery distribution
- Selected BYD battery solution integration
- EVE BESS integration
- PCS and EMS coordination
- System architecture support
- Technical proposal support
- O&M planning
- After-sales coordination
- Future local assembly strategy

Why integration — not just supply — is the real value
Buying a battery is the easy part. The value of a BESS comes from how the battery, PCS, EMS, protection, metering and site load are integrated so the system dispatches safely and performs as one.
Solunar sits in that integration layer — selecting suitable technology, coordinating the system architecture and supporting it through commissioning and O&M — so EPCCs, developers and asset owners can deliver bankable storage without building deep in-house battery capability.
How we engage
A typical Solunar engagement moves through five stages:
- 01
Discovery
We review the project, load profile, site and commercial goals.
- 02
Proposal & sizing
We recommend the battery, PCS and EMS configuration with a technical proposal.
- 03
Design & integration
We coordinate the full system architecture and documentation.
- 04
Commissioning
We support installation, testing and commissioning to specification.
- 05
O&M & after-sales
We plan long-term monitoring, maintenance and warranty support.
Our mission and vision
Solunar Energy is guided by a clear mission and a long-term vision for the region.
Mission
To make Solar + BESS projects easier, safer and more commercially viable for EPCC companies, developers and asset owners.
Vision
To become a leading Solar + BESS technology integration and distribution platform in Malaysia and Southeast Asia.
Frequently Asked Questions
Three things: BESS technology distribution (including GoodWe, BYD and EVE), system integration of battery, PCS, EMS and protection, and long-term O&M for commercial and utility-scale ESS.
As early as the proposal stage, so battery sizing, PCS/EMS selection and O&M planning are correct before pricing is fixed.
No. The EPCC owns the client and site execution; Solunar supports the storage technology layer behind the scenes.
Planning a Solar + BESS project? Bring Solunar in early.
The earlier Solunar is involved, the better the battery sizing, PCS/EMS selection and O&M planning behind your proposal.
