Water-free, portable cleaning bot for rooftop solar

India’s Aegeus Technologies has developed an autonomous, water-free cleaning bot for rooftop solar installations. The bot weighs 5 kg (with battery) and can be operated remotely through a web-based app. It uses an air wash technology to clean the panels, ensuring no need for water or any harmful chemicals.

Compressed air tech for solar module cleaning, cooling shows promise in India field-testing

British scientists have reported significant restoration of the panel performance with the experimental compressed air system developed by them for the simultaneous cleaning and cooling of PV modules. The system was built with a compressed-air unit which was made of a compressor, an air tank, and an airflow regulation valve, and a series of nozzles. The technique was tested on a PV system located in northwestern India.

New model to predict PV module cleaning cycles and resulting profits

A group of scientists in Bangladesh has developed a model to determine the optimal cleaning schedule for a PV installation at any location in the globe, requiring only the average insolation and soiling rate for a given site to make the calculation. The study also draws new conclusions regarding the influence of sandstorms and rain on soiling, and aims to be among the first studies to paint a global picture of soiling trends by region.

Tracking rooftop solar trends in India

Simarpreet Singh, director at EPC firm Hartek Group, speaks to pv magazine about the impact of the Covid pandemic on the rooftop solar sector, technology trends shaping the market, and the outlook for 2021.
