Modular system with solar power supply

Abstract

The invention relates to various modular systems comprising a represented power unit. In one example, the power unit comprises a solar cell, an energy storage device, and one or more power socket interfaces. One of the surfaces of the power unit includes a coupling mechanism that allows the power unit to be coupled with the nio-storage units. In another scheme, the modular system comprises a frame and wheels coupled to the frame to allow the power unit to be transported more easily.
