One of the main advantages of cheap wireless modules is that they get used in consumer electronics, so if you know what’s being used you can build your own compatible hardware. While investigating the RF interface used in a series of cheap “smart” solar inverters [Aaron Christophel], created an Arduino library to receive inverter telemetry using […]

In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel. Let’s get started!

Description After 3 years of development, this open source project is nearing completion. From its modest beginnings it has evolved into a rather sophisticated device with a USB interface, powerful USB charging ports, a 20×4 character LCD, a rotary encoder with push button, precision measurement of everything from voltages and currents to temperatures. There are

The researchers at Soochow University in China, have published a paper on the hybrid device that is able to harness the power of sun and rain using a hybrid panel. By attaching a transparent nanogenerator to a silicon solar cell, researchers have designed a device that harvests solar energy in sunny conditions and the mechanical energy of falling raindrops in rainy conditions. The dual
