New study claims PV industry is neglecting overirradiance issues
Overirradiance conditions may affect the operating performance of photovoltaic plants, the stability of the electrical grid, and the efficiency of inverters. A research team has warned these effects are currently not being given proper consideration by the solar industry.
Teralight announces 314 MW of new solar in Israel
Teralight, via its Solar Tech subsidiary, plans to install new solar fences, rooftops, walls and aquaculture PV projects across Israel. The projects will be built in dozens of villages.
Novel AI-based tech to identify rooftop solar systems from aerial images
The model utilizes deep learning and image processing techniques and is said to offer “superior performance.” In the future, it might be able to differ between panels of PV and solar thermal systems.
Mitigating residential duck curve via solar pre-cooling
Solar pre-cooling consists of using residential PV systems to run air conditioners to pre-cool residential and commercial buildings. It offers benefits in terms of mitigating low minimum demand in electricity networks, flattening the grid’s net demand profile, and reducing electricity bills.
July’s irradiance up in most of South America, down east of the Andes
In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for South America in July. The data show that South America experienced temperatures up to 15 C above winter averages, and that most of the continent saw higher than normal radiation. The Chilean Andine, especially Altiplano in the Atacama Desert, which has recorded the highest incidence of irradiance in the world, recorded values 10% above normal.
Brazil added 6.8 GW of new PV in H1
Brazil installed 2.3 GW of large-scale solar and 4.5 GW of distributed-generation PV in the first six months of this year.
Biwatt unveils new residential sodium-ion batteries
Biwatt Power, a Chinese manufacturer, has developed new residential sodium-ion batteries with an efficiency rate of 97% and a projected lifespan of more than 3,000 cycles.
Solar bus canopy reduces temperature by up to 20 C
The University of Sevilla has designed a PV-powered “smart” canopy that activates a thermal conditioning system to reduce extreme heat by up to 20 C.
Distributed solar as an antidote to illegal roof dwellings
Researchers in Taiwan are proposing a market-based incentive scheme to help property owners to move from using their roofs for illegal dwellings to rooftop solar power generation. They found these owners should be rewarded for solar power generation but also be compensated for the income loss due to the removal of illegal rentals.
Israel surpasses 2.2 GW of rooftop PV capacity
New figures from the Israeli authorities show that the country continues to deploy rooftop PV systems at a rapid pace. New rooftop installations hit 703 MW in 2022, up significantly from 537 MW in 2021 and 296 in 2020.
