In this post I have explained a porch light circuit with programmable timer controller which enables the connected LEDs to light up or shut off after some delay, as preferred by the user, thus it’s not entirely dependent on the solar panel parameters. The idea was requested by “Unknown”. Technical Specifications It’d be neat if […]

Solar Battery Charger using LM339 Comparator
This small LM339 based solar battery charger setup is designed to optimize the charging of your battery using any solar panel while protecting it from accidental overloads. Considering the extended battery life it allows you to achieve, it is an investment that quickly pays for itself. Circuit Description Our setup is nothing more than a […]
Solar Panel Voltage Regulator Circuit
In this post I have explained how to construct a simple solar panel regulator controller circuit at home for charging small batteries such as 12V 7AH battery using small solar panel Using a Solar Panel We all know pretty well about solar panels and their functions. The basic functions of these amazing devices is to […]
Solar, Wind, Hybrid Battery Charger Circuits
In this article I have explained a dual input hybrid solar and wind battery charger circuit using cheap and ordinary components. The idea was requested by one of the interested members of this blog. Technical Specifications Good after noon sir am designing a ” Solar and Wind energy harvest regulator circuit” which has two inputs […]
How to Connect Solar Panels in Series and Parallel
In this post we will study how to connect solar panels in series and parallel and also learn how to calculate solar panels in series and parallel. Before I have explained the connection details, it would be important for us to learn some of the important parameters and specifications related to solar panels. Solar Panel […]
How to Design a Solar Inverter Circuit
When a DC to AC inverter is operated through a solar panel, it is called a solar inverter. The solar panel power is either directly used for operating the inverter or it’s used for charging the inverter battery. In both the case the inverter works without depending on mains utility grid power. Designing a solar […]
