1. A system for harvesting energy, comprising:
a power management system including a solar cell integrated with a display panel into a common housing;
a capacitor and a rechargeable battery connected to the power management system to receive power from the solar cell and to provide electrical power first from the capacitor and then second from the rechargeable battery to electronic components including the display that are engaged in monitoring processes and devices deployed in isolated locations, wherein said electronics include a microprocessor, wherein the microprocessor is programmed to provide data collected from the processes and devices for at least one of display on the display panel and wireless transmission to a remote monitoring station; and
a rotatable stem operated by a step-motor and connected to the display panel housing, wherein the rotatable stem is orientable by the step-motor towards sunlight according to an internal time clock synchronizing movement of the display panel via the step-motor and stem to maintain orientation of the display towards the sunlight and thereby maximize harvesting of electrical energy by the solar cell.
