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.
Message framing techniques to boost solar sales
A Dutch-German research team has tested how a series of framed messages may be used to boost PV system sales, addressing both self-interest and environmental concerns, and has found that all the proposed messages are effective at promoting the purchase of solar panel installations.
Indonesia plans expansion as floating solar plant launched
Indonesia has officially launched the largest floating solar farm in southeast Asia and already the proponents have agreed to more than triple the capacity of the 145 MW project as the nation looks to increase its renewable energy sources and switch away from coal.
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.
Fronius’ Australian marketshare tumbles due to stock shortages, but company says backlog now clear
Fronius, Australia’s most popular inverter brand, has lost almost 35% of its marketshare this year due to major stock shortages. After a year of supply issues, Fronius Australia’s managing director told pv magazine that its backlog, including for the GEN24 Primo 10, should be cleared by the end of November.
Ausgrid turns on community battery as ARENA reveals ‘overwhelming’ demand
New South Wales network operator Ausgrid has switched on the second community battery rolled out under an Australian government national funding program that has sparked an “overwhelming” response with more than $3.5 billion (USD 2.28 billion) of projects seeking funding.
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.
LAVO pivots to new model, offering households renewable ecosystems via subscriptions at no upfront cost
LAVO, which entered the market with its hydrogen battery in 2021, has soft launched a new Energy-as-a-Service model. Partnering with Yingli Solar, LAVO says it can install and maintain solar, battery and EV charging systems at no upfront cost to Australian households, who will then pay off the systems via a 10-year subscription.
