About Photovoltaic panel voltage regulation circuit
We all know pretty well about solar panels and their functions. The basic functions of these amazing devices is to convert solar energy or sun light into electricity. Basically a solar panel is made up with discrete sections of individual photo voltaic cells. Each of these cells are able to generate a tiny magnitude of electrical power.
The voltage acquired from a solar panelis never stable and varies drastically according to the position of the sun and intensity of the sun rays and of course on the degree of incidence over the solar panel. This voltage if fed.
Referring to the proposed solar panel voltage regulator circuit we see a design that utilizes very ordinary components and yet fulfills the needs just.
The following figure shows a high current voltage regulator circuit using the LM338 ICs. The high current is achieved by connecting many number of LM338 Ics in parallelover a single common heatsink. The parallel LM338 are.
The charging current may be selected by appropriately selecting the value of the resistors R3. It can be done by solving the formula: 0.6/R3 = 1/10 battery AH The preset VR1 is adjusted for.Solar Panel Regulator Circuit using IC 741. The majority of typical solar panels provide around 19V off load. This enables to get a drop of 0.6V over a rectifier diode while charging a 12V lead-acid battery. The diode prohibits battery current from moving via the solar panel during night.

supplied from the solar panel, a voltage regulator circuit is used in the curren t model to modulate the variable voltage supply to an almost constant voltage.
The post discusses many simple solar panel voltage regulator circuit diagrams which can be used for charging batteries using solar power.
In this post we will discuss a few simple yet efficient solar voltage regulator circuits using the op amps like IC 741 and TL071. Most common solar panels have an off-load voltage of about 19V. This makes it possible to charge a 12V lead-acid battery and obtain a 0.6V drop across a rectifier diode. When it gets dark, the diode stops battery .
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.
