Residential PV

Scientists in Czechia have proposed to use parallel inverters in PV systems to not only reduce instability, but also to increase power yield. The proposed approach reportedly results in higher maximum power point tracking (MPPT) performance.

Smart metering services provider Intellihub is seeking to develop digital infrastructure that will enable the orchestration of more than 150,000 otherwise scattered consumer energy generation and storage devices, helping to create more than 510 MW of flexible energy demand.

Scientists in the United States has developed a new photovoltaic-thermal system design that utilises parallel water pipes as a cooling system to reduce the operating temperature of photovoltaic panels. The waste heat generated by this process is then used to generate domestic hot water.

Australia’s independent energy markets and power systems operator has warned urgent investment in generation, firming and transmission is needed with forecasts showing the National Electricity Market needs to almost triple its installed capacity in less than 30 years.

Enphase has released 208 V three-phase inverters for the small commercial market. The advancing hardware comes with a specialised support team and tailored design tools.

Just days after a regulation to prevent new gas network connections to buildings in the Australian Capital Territory came into effect, the Victorian government has released updated plans designed to end that state’s reliance on fossil gas.

Scientists in Australia have combined Monte Carlo Ray Trace (MCRT) techniques and electrical modelling to assess the potential energy gains of bifacial rooftop PV systems compared to monofacial arrays. They found that rooftop reflectivity is a key factor in increasing a bifacial PV system performance, and that system and module design should also be carefully considered.

Smoke from wildfires significantly effects solar output, researchers from UNSW have found. Specifically, Australia’s Black Summer in 2019 – 2020 caused energy losses from residential and utility PV systems estimated between 175 to 35 GWh, equating to a worst-case financial loss of around $6.1 to $29 million.

The Queensland government has indicated it will support the increased rollout of household battery energy storage systems with a new $24 million (USD 15.75 million) residential battery rebate program set to be launched in 2024.

Western Australian government-owned utility Synergy’s plan to build a 500 MW/2,000 MWh battery energy storage system in the state’s southwest to improve system security and support increased renewable energy generation in the main grid has been given the tick of approval by planning authorities.
