The Tokyo municipal authorities are working on new regulations to make solar installations mandatory for new homes with total rooftop areas of more than 20 square meters, and for buildings with rooftops smaller than 2,000 square meters.

The China Securities Regulatory Commission (CSRC) has given the green light to the trading of industrial silicon futures on the Guangzhou Futures Exchange. The move could give polysilicon manufacturers the opportunity to hedge against fluctuating silicon metal prices.

Elektroprivreda Crne Gore (EPCG), a utility in Montenegro, said that it has received about 14,000 requests to secure rebates covering up to 20% of rooftop PV system costs. The program is designed to facilitate the deployment of 70 MW of solar capacity.

Panasonic claims that its new vehicle-to-home system can increase the self-consumption rate of residential solar and storage capacity to 90%.

SND has announced plans to build a new factory in Gwangju, South Korea. It will also produce panels with an unspecified tandem technology. It plans to open the factory in 2025.

Amazon says it wants to deploy two hybrid wind-solar facilities in India.

Chinese scientists assessed water evaporation on plots of land covered by two different kinds of agrivoltaic arrays and managed to significantly reduce evaporation in both cases. They looked at the relationship between cumulative surface evaporation and evaporation time.

Brazilian scientists have assessed variations in temperature coefficients in solar modules to determine whether there is a relationship between the dependence of these coefficients and irradiance. They claim their work could be used to improve PV module performance modeling.

Russia’s Hevel Solar said its new modules are based on 166 mm x 166 mm half-cut cells. They reportedly have a bifaciality factor of 90% and a temperature coefficient of -0.26% per degree Celsius.

Moroccan researchers have proposed the use of luminescent solar concentrators for power generation in greenhouses and agrivoltaic projects. They say they are capable of producing electricity in low-light illumination and converting ultraviolet light to visible light that could be used for crops.
