Simplified modeling for partially shaded PV systems
A proposed two-diode model is based exclusively on the standard test condition parameters of solar modules and their irradiance levels. The analytical tool reportedly enables PV system operators to estimate the I-V curves of a shaded array quickly and accurately.
Indian rooftop PV capacity nears 6 GW
Bridge to India figures show dominance of Chinese inverters, which supplied almost 80% of installs from July last year to the end of June.
Italy deployed 362 MW of solar in H1
Developers installed 259 MW of new solar in Italy in the first six months of the year, according to ANIE Rinnovabili. But that doesn’t include a 103 MW plant that was connected to the grid in late June in the southern region of Apulia.
Keeping PV panels honest
Michelle McCann and Lawrence McIntosh, the partners behind the PV Lab panel-testing facility in Canberra, see Australia’s solar installations as a vast, aggregated virtual power plant.
Sweden exempts from energy tax on self-consumption all PV systems of up to 500 kW
On the top of the new fiscal measure, the Swedish government has also announced that the rebate scheme for rooftop PV, which was originally scheduled to be closed this year, will be continued in 2021. It will only apply to municipalities and enterprises and with a limited budget of 260 million SEK ($29.6 million), however.
Residential storage solution with BYD battery, Fronius inverter
BYD and Fronius have started offering the BYD Battery-Box Premium storage system and Fronius Symo GEN24 Plus inverter as a bundle. They said the combined solution can be used in residential PV arrays and light commercial systems.
First Solar brings modules to distributed generation market
The U.S. utility-scale PV pioneer is going small. After decades of avoiding distributed generation, it is now offering its Series 6 modules for ‘projects and customers of all shapes and sizes.’
Repositioning Australian rooftop PV
A University of South Australia study has shown that solar owners selling electricity to the grid should position their panels to minimize the discrepancy between peak use and peak production.
Photovoltaics for highways
The Austrian Institute of Technology, Fraunhofer ISE, and Forster Industrietechnik are developing a new rooftop PV system concept for motorways. They aim to harness the potential of underexploited road networks to generate electricity.
Kstar unveils 1,100 V string inverters
The Chinese manufacturer has designed the new products for the C&I solar segment. They are available in two versions, with 121 kW and 150 kW of AC output and efficiency ratings ranging from 98.7% to 99.0%.
