Abstract: The present invention relates to a solar powered battery charger with voltage regulation circuit and the method for recharging a car battery. The charger comprises an input port for receiving electrical power from a solar panel; an output port for providing electrical power to a battery; and a power regulation circuit electrically coupled to the input power. The power regulation circuit is electrically coupled to the output port and for monitoring a voltage thereon, having a first state in which electrical power is provided to the output port and a second state in which electrical power is not provided to the output port. The power regulation circuit remains in a first state when the voltage at the output port is below a threshold voltage and for other than remaining in the first state when the voltage at the output port is above the threshold voltage.

Abstract: A modular system of mating connector cables for connecting solar power sources to devices requiring power includes connector cables assembled from compatible cable segments, mating connectors and junctions. The cables of the system may be of consistent polarity among various configurations such that current flows through mating connectors at the cable ends. The cables may be variously configured to provide for the connection of solar power sources in series or in parallel, and for connection to devices with various power input connectors or terminals.

Abstract: A solar panel incorporating a selectively actuable energy availability indicator arrangement. The arrangement includes a visual indicator, such as an LED, and a selectively actuable button. Actuation of the button completes a circuit to read the level of energy available. A resistor in series with the LED as it is connected to the terminals of the solar panel limits the current flow through the LED. A blocking diode connected in series with a charging battery prevents the LED from reading the charge of the battery.

Abstract: A portable modular solar battery charger of the lap top style is disclosed. The module includes two body members hingedly interconnected with each body member having a solar panel attached thereto. A circuit is provided for transferring the energy from the solar panels to a battery charger which, in turn, official charges a battery. The modular unit is interconnectable with additional similar modules by both a physical link and an electrical link.
