The Product

A Complete Solar Power Plant in a Container

SolarBox^TM integrates PV generation, deployment structure, electrical protection, inverter interface and monitoring into one transportable platform. It ships like a container, deploys like infrastructure, and operates like a power plant.

Engineered in Singapore. Pre-assembled at the factory. Folded for transit. Unfolded at site.

2 Person Crew, < 3 Hours Deployment Time

A complete 250 kWp solar power plant built into a single 40-ft container deployed at PSA’s Keppel Terminal

Deployment

The container opens and the array extends out across open ground. Foundation-light and self-contained, it brings clean power to rural and off-grid sites in under 3 hours.

Retraction

The same array folds back down and packs into the container, ready to move to the next site. Shipped by road, rail or sea, it can be redeployed on islands and in remote communities wherever power is needed next.

Key Advantages

Faster Deployment

Pre-assembled architecture cuts site works and commissioning time.

Lower LCOE

Engineered for lower delivered cost of energy.

Hybrid-Ready

Integrates with grid, BESS, diesel genset, and load management.

Reduced Civil Works

Foundation-light installation lowers mobilisation cost and complexity.

All-Weather Protection

Containerised electrical equipment and secure stowage mode.

Relocatable Design

Foldable mechanism allows the platform to be moved between project sites.

Configurations & Deployment

How the SolarBox^TM Deploys

The SolarBox^TM scales from a single unit to a 10 MW utility array. Below are four recognised electrical configurations, the on-site deployment sequence, and the use-case fit by sector — so you can pick the right one before we engineer the site.

Each SolarBox^TM: 200 kW AC / 235–250 kWp DC. Configuration totals below are stated in kWp DC.

Industry Applications

SolarBox^TM Use Cases

Mining & Remote Industry

Ideal for temporary mining loads, early-stage operations and staged site development. Relocatable SolarBox^TM unit can be moved and redeployed across multiple mining areas. Battery storage can be added to firm up supply and cover peak or night-time loads.

Agriculture & Plantation

Ideal for irrigation pumping, cold storage and processing loads in fields far from the grid. SolarBox^TM unit can be deployed alongside seasonal or expanding plantation operations and relocated as cultivation areas shift. Battery storage can be added to extend power availability into early morning or evening operations.

Island & Atoll Utilities

Ideal for diesel offset and stable power supply in geographically isolated communities with limited grid access. Battery storage can be added to provide 24-hour power and reduce reliance on diesel backup.

Disaster Relief / Defence

Ideal for rapid-deployment emergency power following natural disasters or in forward operating and temporary defence installations. Fully self-contained, transportable SolarBox^TM unit can be transported and commissioned quickly with minimal infrastructure. Battery storage can be added for uninterrupted, silent and resilient power during critical operations.

Construction Sites

Ideal for temporary site power during builds, replacing or supplementing diesel gensets for tools, lighting and site facilities. Relocatable SolarBox^TM unit moves with the project as it progresses through phases or across multiple sites. Battery storage can be added to smooth out demand peaks and cut fuel costs.

Utility / IPP (Independent Power Producer)

Ideal for grid-connected or hybrid generation projects requiring lower cost, fast deployment and modular capacity expansion. Standardised SolarBox^TM units allow scalable rollout, easy transport to project sites and simplified integration with existing grid infrastructure. Battery storage can be added to enable dispatchable generation and grid stability services.
