How to integrate solar-plus-storage with heat pumps
Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE compared to a PV system relying solely on lithium batteries, while simultaneously increasing PV self-consumption by up to 20%.
Chinese PV Industry Brief: DMEGC posts gains as peers hit by weak Q1
Chinese solar manufacturers have reported mixed first-quarter results. DMEGC recorded strong growth while peers such as HiUV, Risen, Autowell and Jolywood suffered sharp declines amid falling prices and oversupply.
Spain blackout not caused by renewables, says prime minister
Spanish Prime Minister Pedro Sánchez says Spain’s recent blackout was not triggered by excess renewables or a lack of nuclear power. He claims the government will reform the grid, seek an independent report from Brussels, and launch a national inquiry.
ZTT debuts 7.58 MWh liquid-cooled battery storage system
The Energrid NA7 incorporates ZTT’s self-developed 3S-integrated power conversion system (PCS) and supports 2000 V high-voltage DC input.
History repeats as Iberian blackout demonstrates urgent need for battery storage
The vast blackout that gripped the Iberian Peninsula on April 28 has echoes of a similar event in an Australian state in 2016. The solution in both cases appears to be the same.
Solis launches new hybrid inverters for C&I solar
The Chinese manufacturer said its new product is the world’s largest wall-mounted hybrid inverter. The series includes three models, with AC outputs of 80 kW, 100 kW, or 125 kW.
Amazon buying big on solar
For the past five consecutive years, tech and retail giant Amazon has been the world’s largest procurer of renewable energy, investing in projects and signing power purchase agreements (PPAs) all over the world. pv magazine spoke with representatives of the company about its ambitious energy plans.
IBC Solar launches mounting systems for rooftop, facade PV systems
Germany’s IBC Solar has developed two new mounting systems for rooftop and facade PV installations: the WallFix system, made of aluminum and stainless steel, and the AeroFix G3.1, designed for modules up to 3 square meters.
Preventing soiling with surface textured photovoltaic dummies
Scientists in South Africa have used computational fluid dynamics to investigate whether a dummy panel, placed in front of a working PV panel, can mitigate soiling. They have tested this setup with various inclination angles, heights, and distances and have found that the dummies accumulated up to 58% more dust than the PV panels.
