So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]

9 Simple Solar Battery Charger Circuits
Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: In this post I will comprehensively explain nine best yet simple solar battery charger circuits using the IC LM338, transistors, MOSFET, buck converter, etc […]
Simple Solar Tracker System – Mechanism and Working
The circuit and the mechanism I have explained in this article may be considered as the easiest and perfect dual axis solar tracker system. How the Dual Axis Solar Tracker Concept Works The device is able to track the daytime motion of the sun precisely and shift in the vertical axis accordingly. The device also […]
Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
True MPPT Solar Controller Circuit using IC 555
Are you wondering if it was possible to build a very simple MPPT circuit using ordinary parts like IC 555 and IC 741, which would work most efficiently imitating a true MPPT? The answer is yes, it is possible, and we will learn about it details, in the following article. In this design I used […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
