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 […]
Convert SMPS into a Solar Charger
In this post I have explained how to convert smps into a solar charger circuit. The method will result in an extremely efficient and fast solar charging of the connected battery. SMPS Solar Chargers SMPSs have become very common nowadays and we find them being used in the form of AC to DC adapters wherever […]
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 […]
Smart Buck-Boost MPPT Solar Charger Circuit for 12V 24V Battery
In this post we are going to learn how we can make one real working smart solar battery charger circuit which can do MPPT charging. We are using Arduino Nano as the brain for controlling everything. We will also use INA219 sensor module so that we can read the solar voltage and current properly. And […]
