Simple Solar Panel Regulator Circuit

To keep things simple we re using a single nicely made small solar panel for all of these circuits.

Simple solar panel regulator circuit.

Solar panel charge controller wiring intro solar panel charge controller wiring diagram and step by step guide for off grid solar power system wiring. Voltage output is adjustable. 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.

Photovoltaics the process of making electricity from sunlight is growing in popularity among alternative energy enthusiasts. Solar charge controller specifications. 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. Using a current control feature the specialty of the design is that it incorporates a current control feature also.

The panel that we re using for these circuits is this one part number pwr1241 from bg micro about 3 each. This solar charger has current and voltage regulation and also has over voltage cut off facilities. It is mainly intended for charging 12v lead acid batteries. The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode.

Here is the simple circuit to charge 12v 1 3ah rechargeable lead acid battery from the solar panel. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable. The shown solar panel regulator circuit is framed as per the standard mode of the ic 338 configuration. 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 purpose of the box is to regulate the amount of charge going from the panel that flows into the deep cycle battery bank. 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. And for good reasons.
