SunDuino is a Single Board Computer with integrated Battery Charger, Voltage Regulators, I2C, Digital and Analog IO. It’s main benefit is that it can run a compiled C app for years on a small battery or forever using built in solar charger. A background RTOS provides SLEEP functions for reducing operating current to 100ua while providing 125ms periodic wakeups. […]

Build a $1 per Watt parallelizable MPPT controller


https://www.electronics-lab.com/1w-true-mppt/

Jonathan Bruneau designed a $1/W maximum power point tracker used to extract maximum power from solar panels and published his project on hackaday.io: Maximum Power Point Tracking (MPPT) is a technique whereupon special electronics attempts to extract the optimal amount of energy from a solar panel. This optimal point fluctuates in function of a variety […]
