Residential PV

Renewable energy and battery storage has racked up another banner year in 2021, according to end-of-year analysis from Rystad Energy. While there was growth across segments, residential solar has seen the most impressive gains, surpassing the commercial and industrial (C&I) segment for the year.

Indigenous communities have some of the most unreliable, expensive power in Australia, with a recent study finding almost three quarters of households in remote Northern Territory communities lost power more than 10 times, often for significant periods on “dangerously” hot days. Alarmingly, regulations have until now completely blocked communities in public housing from connecting rooftop solar because they use a prepaid meter system.

Western Australian renewable energy company Plico Energy’s bold ambition to develop a grid-scale virtual power plant has received a major financial boost with Swiss investment firm SUSI Partners committing to provide capital for the rollout of 10,000 integrated solar-plus-battery systems.

Perth-based Hybrid Systems Australia has opened its new much-expanded facility in the Western Australian capital ahead of significant expansion in the outlay of its stand-alone power systems to regional and remote parts of the state.

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

Germany’s Home Power Solutions has developed a hydrogen storage solution with a capacity of up to 15,000 kWh. The Picea system stores excess electricity from rooftop PV systems in the form of green hydrogen.

Scientists have developed a new model based on fault tree analysis to evaluate the frequency of fires caused by rooftop PV systems and assess system safety and reliability. They claim that the new tool has the potential to identify fault linkages in systems, highlight failure patterns before they arise, and compare multiple designs for safety.

Simply Energy on Thursday announced it will be extending its Virtual Power Plant program across the eastern seaboard and opening it up to five different battery brands. Simply Energy will continue its technology partnership with SwitchDin to do so, with Ryan Wavish, Simply’s General Manager, and Andrew Mears, CEO and founder of SwitchDin, telling pv magazine Australia they plan to introduce a whole range of new, more advanced features into the VPP as the relationship between the two companies evolves.

Western Australia has today announced the launch of its $35.5 million Virtual Power Plant trial, Project Symphony, which will examine the ways in which residents, utilities, and network operators can join forces to centrally orchestrate the output of rooftop solar, batteries and other distributed resources to best serve both customers and the grid at large.

Western Australia has become the second state to give network operators the capacity to remotely switch off residential solar systems as an emergency grid stability mechanism.
