MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611100495 A) filed by Madan Mohan Malaviya University Of Technology on August 19, 2026, for Low-Cost Iot-Integrated Solar Irradiance Measurement System Using Short-Circuit Current Calibration.
Inventors include Ashok Kumar Pandey; Gaurav Kumar Mishra; and Om Hari Gupta.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A low-cost, IoT-integrated solar irradiance measurement system (100) and method estimate incident solar irradiance using the short-circuit current of a photovoltaic panel. The system (100) comprises a main photovoltaic panel (101) acting as a sensing surface, an ACS712 current sensor (103), a potential-divider voltage sensor (104), a DHT11 temperature sensor (105), and an ESP32 development board (106). The ESP32 board (106) acquires analog sensor signals, performs analog-to-digital conversion, and computes the solar irradiance value using a calibrated, temperature-compensated short-circuit current formula. The computed irradiance and electrical parameters are transmitted via Wi-Fi to a ThingSpeak IoT cloud platform (109) for real-time remote monitoring, logging, and graphical visualization. A secondary check photovoltaic panel (102) is optionally used alongside the main panel (101) to compute percentage error for measurement cross-validation. Powered by a rechargeable battery (107), the standalone system provides an economical alternative to pyranometers for solar resource assessment.
