Faststream Technologies offers an automated IOT based solar panel monitoring/troubleshooting system that allows for automated solar panel monitoring from anywhere over the internet. As part of our solution, we make use of several IoT gateways suitable for different needs, based on SoCs like STM32, ESP32, ublox, CC3200, SiliconLabs, to monitor the solar panel parameters, in turn, providing Solar Plant Insights. Our system constantly monitors the solar panel and transmits various parameters to the Cloud over the IoT system. Here we make use of the IoT platform to transmit solar power parameters to Amazon/ Azure cloud /IOT server via the gateway (over WiFi and Ethernet). A powerful web interface allows viewing of data in meaningful formats, enabling users to make decisions.

6. ▪ The alerts originated from Panel comes to rescue in tackling situations like output falling below specific limits
or some sort of malfunctioning. This makes remote monitoring/handling of solar plants very seamless and
intuitive,addressing faults within stipulated time..
▪ We also have Alerts and monitoring interface on Android/iPhone for distributed Solar Panel Monitoring System
(SPMS). This method utilizes the Bluetooth interface of Android/iPhone as a communication link for data
exchange with digital hardware of the Solar Unit.
▪ Introduction to an instant monitoring solar panel system, that is constituted with a sensor on current and
voltage measurements of each panel source, the related values are measured with the developed sensing
circuits and processed by 18F4450 microcontroller of Microchip.
▪ The processed parameters are then transmitted to the personal computer (PC) over MODBUS to be saved in
the database and to observe the system instantly. The Coded visual interface of monitoring software can
manage the saved data to analyze daily, weekly and monthly values of each measurement separately.

11.  In case of Internet disruption, the collected data would be stored in Local memory. Minute by Minute data of up
to 60 days can be stored in Local Memory. Once the Internet service resumes, this data is uploadedto the
Server with their original timestamps.
 Data transfer between Server and Data Concentrator Gateway can be realized using JSON as well as MQTT
format.
 The Gateway can be used to remotely restart selectivelyany given Wireless Node within its Network.
 Complete wireless network health can be monitored by remotely connecting to the Gateway.
