Simple Solar Panel Regulator Circuit

Voltage output is adjustable.

Simple solar panel regulator circuit.

This low dropout voltage ldo solar charge controller uses a simple differential amplifier and series p channel mosfet linear regulator their compatibility seems like a marriage made in heaven. The shown solar panel regulator circuit is framed as per the standard mode of the ic 338 configuration. The panel that we re using for these circuits is this one part number pwr1241 from bg micro about 3 each. Using a current control feature the specialty of the design is that it incorporates a current control feature also.

Photovoltaics the process of making electricity from sunlight is growing in popularity among alternative energy enthusiasts. The pot or the preset is used to accurately set the voltage level that may be considered as the safe value for the battery. And for good reasons. The purpose of the box is to regulate the amount of charge going from the panel that flows into the deep cycle battery bank.

It is mainly intended for charging 12v lead acid batteries. Solar charge controller specifications. The input is given to the shown input points of the ic and the output for the battery received at the output of the ic. To keep things simple we re using a single nicely made small solar panel for all of these circuits.

The first part of a solar circuit is a device for collecting sunlight. Connecting the solar panel charge controller mppt or pwm are the same solar battery and the pv array in the right way is the essential work before enjoying the solar energy. The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode. The circuit of a simple lm338 solar battery charger is shown below using the ic lm338.

This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable. A solar regulator is a small box made up of circuitry in a solid state that is located between a battery and a solar panel.
