MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611106973 A) filed by Chandigarh University on September 05, 2026, for Self-Cleaning Solar Panel System Using Piezoelectric Vibration And Iot-Based Dust Monitoring.
Inventors include Kaljot Sharma; and Pawandeep Kaur.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a self-cleaning photovoltaic (PV) panel system (100) comprising a PV panel (101), piezoelectric actuator strips and driver circuit (102), microcontroller (104), dust sensor (105), battery (106), power management circuit (107), DC regulated outputs (108), IoT/cloud link (103), user dashboard interface (109), and cloud server (110). The dust sensor (105) continuously detects dust accumulation on the PV panel (101), and the microcontroller (104) compares the detected dust level with a calibrated threshold. When the threshold is exceeded and a weather API indicates a low probability of imminent rain, the microcontroller (104) activates the piezoelectric actuator strips (201e), generating high-frequency vibrations to dislodge dust without water or physical contact. The dislodged dust slides off under gravity. Cleaning events, dust levels, and estimated power recovery are transmitted through the IoT/cloud link (103) to the user dashboard (109), enabling remote monitoring and predictive maintenance.
