Technology and R&D

Renew Home, a partnership between Google Nest Renew and OhmConnect, aims to expand from 3 GW of electrical energy use to 50 GW by 2030.

AGL Energy has completed the installation of a solar-powered microgrid with a 5.4 MWh battery energy storage system in Australia to support the transition of a commercial orchard’s operations from diesel to renewables.

A research group in China has tested how membrane-based floating PV platforms can operate in offgrid scenarios. Their analysis showed that, especially with high wave frequencies, this kind of floating PV installation may suffer from the floater bending stiffness, which could limit both in-plane and out-of-plane motion amplitude.

Researchers from the Argonne National Laboratory have concluded that renewable energy could partially replace diesel fuel to power instruments and provide heat at the South Pole. They have proposed a solar, wind and energy storage hybrid that could reduce diesel consumption by 95% and save approximately $57 million over 15 years, after an initial investment of $9.7 million.

Indian scientists have designed an off-grid power system that relies on solar panels, lithium-ion batteries and Ćuk converters. The converters are the crucial components that enable the system to deal with varying input voltage due to changing sunlight conditions.

Midea says its new outdoor residential Evox G3 Heat Pump ranges in size from 1.5 tons to 5 tons, with a coefficient of performance of 1.8. It features enhanced vapor injection technology and uses A2L as the refrigerant.

Scientists in Czechia have conducted a techno-economic analysis of a green hydrogen production system powered exclusively by photovoltaic and wind energy. The system uses surplus energy for water treatment and, according to its creator, can achieve a levelized cost of hydrogen of $3.12/kg.

Researchers in Japan have analyzed the warming effect of photovoltaic system on land surface temperature around the Kushida River Basin for ten years and have found this value increased by an average of 2.85 C.

Under Czechia’s new rules for agrivoltaics, farmers and developers will not need approval to change land designations and zoning plans for agricultural areas devoted to PV generation. The provisions currently only allow agrivoltaics to be deployed in orchards and vineyards.

The solar modules are based on the record-breaking 25.32%-efficient 2D/3D perovskite solar cells that the Ecole Polytechnique Fédérale de Lausanne unveiled in July 2023. The panel has an aperture area of 27.22 cm2, and were encapsulated by glass-glass encapsulation technology combined with an edge seal of the module under UV light illumination.
