The brains are an Arduino glued to a large amount of solar support electronics and the online energy monitor component is covered by an ESP8266. The construction works quite well.

The system was presented in the paper “ Solar PV tracking system using arithmetic optimization with dual axis and sensor,” published in Measurement: Sensors.

The dual-axis solar tracker market analysis identifies Germany and Turkey as the major contributors to the growth of the market in the EMEA region in 2018.

The global dual axis tracker market is in nascent phase, and it is likely to grow at a rapid rate on account of increasing focus on enhancing the energy produced from solar power systems.

The increasing development of dual-axis solar trackers with advanced tracking algorithms, sensors, and control systems has improved the accuracy and efficiency of dual-axis solar trackers.

Combining two existing technologies, bifacial panels and dual axis tracking, will have significant economic and energy advantages.

According to Technavio Research Report "Dual-Axis Solar Tracker Market by application (utility and non-utility) and geographic regions (APAC, EMEA, and the Americas) is witnessed to grow USD 432. ...
