A German PV system owner has developed a simple solution intended at preventing the birds from nesting under the modules.

The new module series has a power output ranging from 370 to 380 W, a temperature coefficient of -0.26% per degree Celsius, and an efficiency of up to 21.7%.

‘One Sun One World One Grid’ is a global supergrid project proposed by India for seamless sharing of renewable energy resources among countries. The inception workshop was attended by more than 160 experts and discussed the roadmap of the project.

Slovenian solar module manufacturer Bisol has developed a white panel with a power output of 190 W. The product is claimed to be an ideal solution for seamlessly blending with large surface buildings and maintaining their historic character.

The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.

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.

A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.

Spanish PV project developer Gransolar is planning to build a large-scale green hydrogen production plant in the Port of Almería, in southern Spain.

Developed by a French-Canadian research group, the triple-junction cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of only 0.089 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).

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.
