We offer two types of solar containers that differ in design and power output. Besides our flagship, auto-foldable container, we also offer the manual version of this unit.
Built in a 40ft High Cube foldable container, this all-in-one portable system is tailored for long-term off-grid operations requiring ultra-high capacity and energy security.
With scalable solar capacity of 30-200kW and battery storage options from 50-500KWh, Solarfold™ provides reliable power wherever you need it - from remote construction sites to disaster relief
Foldable Photovoltaic Power Generation Cabin is a containerised solar power solution. Combining the features of solar power generation and mobility, it provides electricity all over the world.
The off-grid version consists of a Solarfold container which, in conjunction with a suitable additional storage container, is not connected to the public power grid and functions completely autonomously.
The container is equipped with foldable high-efficiency solar panels, holding 168–336 panels that deliver 50–168 kWp of power. It is the perfect alternative to unstable grid power and
This is the product of combining collapsible solar panels with a reinforced shipping container to provide a mobile solar power system for off-grid or remote locations.
Investors are scrambling to put solar container ideas into boxes for their modularity—having the ability to add multiple pieces to scale up capacity or re-configure components
Our pioneering and environmentally friendly solar systems: Folded solar panels in a container frame with corresponding standard dimensions, easy to unfold thanks to a sophisticated rail system and no
