Topography-induced shading on floating PV
Researchers in Turkey have studied the impacts of topography-induced shading on floating PV at the Ayvalı hydroelectric power plant and have identified differences between the regions with the highest and lowest electricity production potential.
Lumartix unveils solar simulator with plasma-light engine
Switerzland-based Lumartix has developed a steady-state solar simulator system for research labs. It claims a light emitter lifetime of more than 20,000 hours.
High pressure stalls El Nino’s expected solar boost in eastern Australia
In a new weekly update for pv magazine, Solcast, a DNV company, reports that eastern Australia’s behind-the-meter normalized generation has fallen by 10% to 15% year on year.
Optical photovoltaic converters for power transmission systems
Researchers from Spain have developed a novel model to evaluate optical photovoltaic converters used in high-power optical transmission. They have found that indium gallium nitride (InGaN) and indium aluminum nitride (InAlN) semiconductors could provide better results than gallium arsenide (GaAs).
Vaysunic launches hybrid photovoltaic water heater
The Chinese manufacturer says that its new V series heaters can use either PV or AC grid power. It can also be controlled and monitored via WiFi.
How to integrate residential solar-plus-storage with vehicle-to-home systems
Researchers from Australia have created a model to optimize the interaction between vehicle-to-home (V2H) systems and residential PV connected to battery storage. They claim V2H can help reduce the cost of energy by 16.7% for workplace charging and 25% for public charging.
FAS Energy, Marubeni secure development deal for Saudi Arabia’s largest rooftop PV project
The project consists of a 52 MW portfolio to be deployed across several locations in Saudi Arabia, including cities such as Jeddah, Riyadh, Khobar, Medina, and Mecca. The solar arrays will sell power to Saudi retailer Cenomi Centers under 20-year PPAs.
Denmark supports first energy communities
The Danish Energy Agency says it dished out a total of DKK 4.2 million ($61,9542) in grant funding this year to nine local energy communities and projects supporting renewable energy. Projects include an energy community start-up guide for rural environmentalists to an energy community feasibility study in a decades-old garden association.
Vaysunic releases new microinverters
Chinese manufacturer Vaysunic New Energy has developed eight versions of its VM microinverters. Their AC output power ranges from 600 W to 1,000 W.
Johnson Controls unveils water-to-water heat pump for commercial buildings
US-based Johnson Controls says its new 1,406 kW compound centrifugal heat pump is able to deliver high-temperature hot water as high as 77 C.The system reportedly has a combined coefficient of performance of 4.9.
