Virtual power plant for renewables trading under development in Greece
Optimus Energy has announced a virtual power plant for renewables trading on the Greek wholesale electricity and balancing market. Work is already underway, with Germany-based emsys VPP connecting over 3,500 solar and wind power plants in Greece to its software suite.
Teledyne Flir presents new PV inspection products
Teledyne Flir, a US-based sensing solutions company, has launched new PV inspection tools – including a clamp meter, irradiance meter, and I-V curve tracer – alongside two product kits targeting solar installers, utilities, and PV manufacturers.
Australian researchers build 2D/3D tin halide perovskite solar cell with 16.65% efficiency
Researchers at the University of Queensland have developed a 2D/3D tin halide perovskite (THP) solar cell with a certified efficiency of 16.65% and peak performance of 17.13%, maintaining stable output under continuous illumination for over 1,500 hours.
PV-driven heating, cooling system for supermarkets
Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.
Longi achieves 34.85% efficiency for two-terminal tandem perovskite solar cell
The result was confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
CIGS cell with ultra-thin glass substrate hits record efficiency of 17.81%
South Korean researchers have fabricated a copper indium gallium selenide (CIGS) solar cell with a 90 μm-thick UTG provided by South Korea’s Unique Technology Integral. The device uses a cadmium-free buffer layer made of zinc oxide and magnesium oxide, instead of cadmium sulfide.
Testing floating PV at different heights
Scientists have tested the performance of floating PV panels at a height of 800 mm and 250 mm above their floating structures. Their thermal and electrical performance was compared to that of a reference land-based system and the highest panel was found to show the greatest cooling effect.
Irish and UK grids linked via 500 MW subsea HVDC cable
The Greenlink Interconnector comprises two high-voltage direct current (HVDC) cables reaching across the Irish Sea connecting the grids of Ireland and the United Kingdom at the Great Island substation in County Wexford and Pembroke substation in Pembrokeshire, Wales.
UL battery safety standard updated for new storage chemistries
Underwriters Laboratories (UL) says the fifth edition of its ANSI/CAN/UL 9540A standard addresses technology such as sodium-ion batteries and new use-cases including rooftop installations.
Rept Battero launches 392 Ah cell, 6.26 MWh storage system
Rept Battero’s new 392 Ah battery energy storage system (BESS) cell is an all-rounder, with the same size but increased energy density over a previously manufactured cell.
