Residential PV

New research from Lappeenranta University of Technology shows that there is no single correct orientation for a PV installation.

Australian renewable energy tech start-up Okra Solar has raised $3 million to scale up distribution of its solar-based hardware and software solutions and electrify more than 290,000 off-grid homes in Nigeria in the next three years while expanding its operations in Haiti and other countries.

After a bumpy start, the Victorian government’s Solar Homes Program is now in full swing, lead by strong uptake in Melbourne’s suburbs and the state’s rural north. Meanwhile, demand for batteries linked to rooftop solar has skyrocketed over the last month, spurred by the energy crisis and an especially cold winter.

Western Australia’s regional utility Western Power has confirmed plans to install another 4,000 standalone power systems across the state in the next 10 years after reaching a milestone in the rollout of the renewable energy units.

Sydney-based solar company Solaray Energy says its inquiries have doubled since the federal election, rebounding back to the record demand seen in 2020 ad 2021. Moreover, the company’s director and co-founder Jonathan Fisk says interest in batteries is “making solar fly,” with half of the potential new customers looking to add storage.

Australia’s uptake of rooftop solar is one of the highest in the world with more than 30% of free-standing households across the nation now fitted with a PV system but the Clean Energy Regulator has revealed a “steep decline” in the number of installations in early 2022 with deteriorating economics playing a major part.

Solar installers and resellers can now access up to $250,000 on interest-free terms to increase their stocks of Australian-made solar panels after PV module manufacturer Tindo Solar teamed with business financer Moula Pay.

Scientists in the United States have developed a new model to allow utilities to use grid-forming inverters in order to better manage renewable energy intermittency. They describe the inverter main circuit representation, the droop control, and the fault current limiting function.

Swiss module manufacturer Megasol has unveiled a novel rooftop PV system in two variants — full-black and translucent. The installation consists of vertical supports, a ridge profile, and solar modules.

The battery has a rated output of 5.5 kW and can be installed in outdoor environments. It is equipped with a hybrid power conditioner, a DC-to-DC converter, and a vehicle power supply adapter with a maximum output of 1.1 kWh.
