Solar powered illumination system
The illumination system includes at least one solar panel, a charge controller, a rechargeable battery, an illumination unit connected to the battery through the controller, and a base frame supporting the solar panel and illumination unit at a top portion thereof, with the battery provided in a bottom portion of the base frame.
1. A solar based illumination system comprising:
a solar panel unit, having at least one solar panel, a rechargeable battery and a charge controller electrically interconnecting the solar panel and the rechargeable battery;
at least one illumination panel electrically connected to the rechargeable battery through the charge controller; and
a base frame supporting the at least one solar panel and the illumination panel at a vertically top position of the base frame, with the rechargeable battery attached to a bottom surface of the base frame,
wherein, the charge controller is configured to sense a voltage output from the solar panel, activate the illumination unit when the voltage output is below a predetermined value, regulate an input current to the battery, sense a charge status of the battery, and based on the charge status, route an excess of the input current to the illumination unit; and
wherein the luminescence of the illumination unit is constant for 5-10 nights in low light conditions and gradually decreases for next 5-8 nights.
2. The illumination system according to claim 1 , wherein the predetermined value is 5V.
3. The illumination system according to claim 1 , wherein power consumption of the illumination system is in the range of 36 watts to 280 watts.
4. The illumination system according to claim 1 , wherein the charge controller implements a buck-boost converter for charging the rechargeable battery at lower voltages during an inclement weather.
5. The illumination system according to claim 1 , the at least one illumination panel includes a plurality of illumination panels, each of such illumination panels connected in parallel with the charge controller such that, upon failure of one of the illumination panels, the other illumination panels continue to function.
6. The illumination system according to claim 1 , wherein charging controller is configured to provide a constant power level to the illumination unit.
