Simple Solar Panel Regulator Circuit

Using a current control feature the specialty of the design is that it incorporates a current control feature also.

Simple solar panel regulator circuit. 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. This circuit uses the solar cell for dark detection this charges the batteries and turns the led on when the solar cell is in the sun or turns off the led when the solar cell is in the dark not charging the batteries. To keep things simple we re using a single nicely made small solar panel for all of these circuits.

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. Solar panel charge controller wiring intro solar panel charge controller wiring diagram and step by step guide for off grid solar power system wiring. 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. The pot or the preset is used to accurately set the voltage level that may be considered as the safe value for the battery.

Solar charge controller specifications. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable. Photovoltaics the process of making electricity from sunlight is growing in popularity among alternative energy enthusiasts. The first part of a solar circuit is a device for collecting sunlight.

Here is the simple circuit to charge 12v 1 3ah rechargeable lead acid battery from the solar panel. 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 shown solar panel regulator circuit is framed as per the standard mode of the ic 338 configuration. The circuit of a simple lm338 solar battery charger is shown below using the ic lm338.

And for good reasons. The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode. It is mainly intended for charging 12v lead acid batteries.
