New MPPT approach for multi-string PV systems under partial shading
Egyptian researchers has developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).
Residential photovoltaic panels with high partial shading tolerance, high voltage
Scientists from South Korea have designed new photovoltaic modules with both rectangular and triangular shapes and solar cells connected in parallel, which they said have higher partial-shading tolerance compared with cells connected in strings. The panels are reportedly less sensitive to partial-shading geometries than shingled modules.
Researchers shed light on mysterious, higher energy yields in vertical PV systems
Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.
Feasibility-first value selling – a turbocharger for commercial installer growth
A ‘Feasibility First Value Selling’ can transform solar sales processes, James Allston of Orkestra argues.
CleanPeak continues growth in utility scale solar sector
Australian commercial solar outfit CleanPeak Energy has expanded its utility-scale PV portfolio with the acquisition of three operating solar farms with a combined capacity of 14.3 MW in Western Australia and the Australian Capital Territory.
Solar-plus-storage outperforms diesel in US military survival analysis
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has determined that Antora Energy’s solar-plus-storage system meets the US military’s stringent standards, as it significantly outperforms emergency diesel generators in survivability probabilities.
Novel tool for PV system sizing allows users to assess tradeoffs between reliability and costs
Developed by scientists in Egypt, trhe Green Energy Solutions software allows users to assess the tradeoffs between the PV system reliability and its costs. Compared to PVsyst, it has an error margin of up to 9%.
Weekend read: the ‘next big thing’
The PV industry in Southeast Asia has come a long way since guest author Ragna Schmidt-Haupt, partner at Everoze, reported on solar financing innovation in the region more than a decade ago. In this article, she outlines five factors for success, the newest of which has the potential to become a game changer, and not only in Southeast Asia.
AIKO showcases ABC modules ahead of Australian launch
Chinese solar panel manufacturer AIKO unveiled its solar cell technology at Melbourne’s All-Energy event last week ahead of an impending entry into the Australian market.
Agrivoltaics and the art of farming under cover
Ground-mounted PV is increasingly being investigated not only as a renewable generator, but as shelter for crops and creatures under fire from climate change. Last week’s All Energy conference handed the mike to some pioneers in the field.
