Residential PV

Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.

Australia’s world-leading uptake of distributed energy resources introduces potential new entry points to the grid, ushering in a legion of complex and novel cybersecurity considerations. The first in a two-part series, pv magazine Australia talks to experts about at what’s being done in this rapidly evolving landscape and where vulnerabilities lay.

Scientists in Europe have put together a comprehensive guide to PV module degradation, examining literature and case studies on the topic as far back as the 1990s. Their paper details the primary stress factors faced by modules in the field, the most common modes of degradation and failure, and provides clear definitions relevant to reliability, quality and testing standards. Among their key findings is that a full understanding of how combinations of different stresses over varying timeframes is still missing from methods to estimate and improve system reliability.

New PV capacity additions in Southeast Asia are expected to bounce back this year for the first time since 2020, according to the Asian Photovoltaic Industry Association. The market is expected to grow by 13% in 2023, for 3.8 GW of new installations.

Samsung and SMA are using a new cloud-to-cloud system that allows PV systems with SMA inverters to be integrated with Samsung heat pumps.

SolarEdge has released new optimisers for residential PV applications with a DC power rating of 500 W, a maximum efficiency of 99.5%, and a weighted efficiency of 98.6%. The optimiser for commercial and industrial applications offers 1.4 kW of rated DC power.

The world installed 239 GW of new solar capacity in 2022, according to SolarPower Europe. The rooftop PV segment accounted for 49.5% of additions – the highest share in the past three years. The rooftop sectors in Brazil, Italy, and Spain grew by 193%, 127%, and 105%, respectively.

The Clean Energy Finance Corporation has awarded the Australian arm of Malaysia-headquartered property developer Mulpha an $80 million (USD 53.95 million) loan to help deliver the first stage of an energy-efficient apartment development in Sydney’s Hills district which is to be powered by 100% renewable energy.

Australia is set to electrify everything. Vibrant communities willing to trial the transition are the first in line to learn what to do and how to bring everyone along, reports pv magazine Australia’s Natalie Filatoff.
