ESP32 solar tracker voltage, current, and servo positions.

This is data showing water volume for a reservoir. Reservoir devices are off the grid (no power, wifi) and use an AVR Iot Cellular Mini with JSN-SR04T sensors using cellular to post data. Variations use LiPo bat or capacitor plus solar panel for power.

Remote monitoring of solar system array, battery bank and auxiliary battery charger status.

DIY Weather Station Guadarrama - Spain

In large solar farms ,it is difficult to monitor parameters of individual pannel so we are introducing remote parameter monitoring with IoT as well as we are introduing cleaning system so that efficiency will increase and also we can monitor parameters re
