rooftop solar

The Victorian government has announced a new $10 million (USD 6.7 million) grants program to provide bulk rebates for the installation of solar panels, solar hot water systems and heat pumps as part of plans for all new homes in the state to be 100% electric from 2024.

The Alpha 150 battery, produced in the Netherlands by Adelaide-headquarted electronics manufacturer Redarc, has a lifespan of more than 5,000 cycles and a continuous discharge rating of 200 A.

Solar generation in Australia’s main electricity grid has surged to record highs with the latest data from the Australian Energy Market Operator revealing that rooftop solar generation increased 30% in the second quarter of 2023 while grid-scale solar output rose by 37%.

Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a.

Addressing climate change means enduring some economic pain in the early part of this century to avoid worse outcomes in the long run. But recently the narrative has shifted from pain to opportunity.

A grid-connected community battery has gone live in Sydney’s western suburbs with New South Wales electricity distributor Endeavour Energy trialling the technology as a means to maximise the benefits of rooftop solar generation and more efficiently manage supply and demand in the network.

A new report released by Australia’s national science agency shows that renewables, led by large-scale and rooftop solar, remain the cheapest form of new-build power generation in Australia despite a 20% average rise in technology costs.

The founder and deputy chair of Australian-based investment firm St Baker Energy Innovation Fund plans to establish a lithium-ion phosphate battery manufacturing plant in the Philippines with annual production capacity of 1.2 GWh by the end of the decade.

Solar data and forecasting provider Solcast, a DNV company, has detailed the solar irradiance data it collected for Australia in June, showing that eastern New South Wales received irradiance about 15% above normal for the month, while central and western Victoria received totals 10-20% lower than normal.

Viridian offers five versions of its new residential inverters, with power outputs ranging from 1 kW to 3 kW and an efficiency ranging from 97.2% and 97.6%. The European efficiency is 96.4% to 97.2%.
