Simple Solar Panel Circuit

Referring to the circuit diagram we are able to witness a simple set up using a solar panel an inverter and a battery.

Simple solar panel circuit.

In the above case the regulator needs to produce around 7 to 10amps of current therefore an lm396 or lm196 must be used in the charger. In this circuit the solar panel charges up a 3 cell nimh battery 3 6 v. A diode d1 protects the target device against a negative voltage in case the solar panel is installed in reverse. This one way valve allows current to flow from the solar panel to the battery but does not allow current to flow backwards out of the battery through the solar panel.

Simple solar led light circuit last updated on february 17 2018 by admin leave a comment the following easy solar light circuit is made for charging a battery pack for the duration of day time or so long as the solar panel is producing electricity as well as for lighting up a coupled led as the panel is not operative. Between the two is a reverse blocking diode. However if the solar panel is smaller in size and unable to generate sufficient power it may be used just for charging the battery and becomes useful for operating the inverter only after sunset. A simple solar panel voltage regulator circuit may be witnessed in the following diagram the given switch may be used for selecting a battery charging option or directly driving the inverter through the panel.

The ones that only need minor repairs i repair and the ones that need major work i strip for parts and reverse engineer the circuit boards. Each spring i gather solar lights my neighbors tossed in the garbage after the lights have stopped working.
