Compiled by an international research group, the best practices were collected from all available guidelines published by national agencies, regulatory bodies, and trade associations.

The list of the eligible renewable energy producers also includes 36 hydropower facilities totalling 412.8MW, 36 biomass schemes with an aggregate capacity of 264.8MW, seven wind farms with a total power of 409.9MW, and six geothermal power plants totalling 218.5MW.

A Japanese group has developed a storage system with potential applications in residential storage, electric vehicles, drones and Internet-of-Things devices.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

The new heterojunction module series is compatible with Panasonic’s Evervolt battery and has a power output ranging from 400 to 410 W. It also features a temperature coefficient of -0.26% per degree Celsius.

Scientists in the United States have proposed to use a thermochemical energy storage (TCES) technique that stores energy in chemical bonds to recover the heat produced during air compression operations. According to them, this innovation may increase the round-trip efficiency of compressed air energy storage to 60%.

Recent research from Thailand has shown that solar-plus-storage on floating platforms could be the cheapest option to power energy-intensive aeration systems in aquaculture projects. The battery accounts for around 54% of the capital costs, which is why system sizing would be key for economic viability.

The solar roof was developed in collaboration with the Fraunhofer Institute for Solar Energy Systems.

Researchers in Singapore have created a flexible framework for designing hotspot-resistant shingled modules. Their work is claimed to be perfectly compatible with existing manufacturing techniques.

Huaneng Power International has switched on a 320 MW floating PV array in China’s Shandong province. It deployed the plant in two phases on a reservoir near its 2.65 GW Dezhou thermal power station.
