The present invention of Portable Multi-Function Dual-Pass Tray Dryer has the uniqueness of direct dual-pass heating, heated air-flow convection, portability, light weight, and energy efficient (thru harvesting dissipated heat energy).

This AvKg system integrates Photovoltaic system with agriculture plots specifically for kitchen-related crops . This system is designed to cater for any planting pots inclusive with dripper fertigation system and solar PV panels.

The uniqueness of the PvWPS invention is upgrading the traditional solar still mechanism by harvesting the dissipated heat under PV array module for increasing the evaporation rate.

This product is customarily design for Agrivoltaic Ground Mounted PV system. It could minimize the problems for farmers especially when working under PV arrays (semi-confined working space) and could save time, energy, risk and labour cost.
