Micro-inverter for high-power solar panels from Hoymiles
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.
Panasonic unveils 410 W solar panel with 22.2% efficiency
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.
Improving compressed air energy storage efficiency via chemical reactions
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%.
Weekend read: Solar-plus-storage for aquaculture aeration
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.
Mercedes’ newest electric car comes with thin-film solar cells on the roof
The solar roof was developed in collaboration with the Fraunhofer Institute for Solar Energy Systems.
Novel design for shingled solar modules
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.
World’s largest floating PV plant goes online in China
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.
Construction begins on 500MW solar park in the Philippines
The solar park is part of a 1GW portfolio of unsubsidised PV projects. Completion is scheduled for 2023.
Floating solar array powering recreational park in Vietnam
The 600 kW array was built by Sungrow with 540 W solar panels and its own floating structures.
Perovskite solar cell retains 99% of initial efficiency after 1,450 hours
Developed by German researchers, the 20.9%-efficient device was built with an architecture avoiding the use of the ionic dopants or metal oxide nanoparticles that are commonly used to contact the cell, as these can be subject to secondary reactions at higher temperatures.
