Solar 101: How to evaluate solar contractors for rooftop projects
A well-designed rooftop solar system should last 20 or 30 years, or longer. This guide for choosing the right contractor should help ease your concerns.
Jolywood signs megadeal with Chinese utility to supply 7 GW of household solar
Based on current market prices, the five-year contract could be worth almost $4 billion to the $1 billion company, but the TOPCon manufacturer has not publicised the price at which it will supply and install modules for its state-owned sponsor.
A string of off-grid solar-powered data centres will transform regional business
Edge Centres’ model for grid-independent data distribution at the edge of connectivity is set to rock regional Australia with its low-cost reliability, and has been welcomed by solar operators in Japan.
Sunny lifestyle: sonnen Australia adds EV subscription to its clean-energy offering
Revving up the appetite for EVs, sonnen and Carbar join forces to make electric car “ownership” easy. A new subscription model, with all running costs included, and the ability to trade up at two weeks’ notice, may supersede buying altogether.
Can hydrogen bump diesel to power large-scale agriculture?
Third-generation Wimmera-Mallee farmer Thomas Blair is expanding his fellow farmers’ horizons to cultivate green hydrogen.
New stack design for cheaper redox flow batteries
German scientists have proposed a new design for stacks used in redox flow batteries. Through a powder-to-roll process, a device that weighs 80% less than a conventional stack was fabricated.
Going with the vanadium flow: Yadlamalka battery takes shape
A new South Australian big battery will show the value of deploying diverse storage technologies in the NEM. Matt Harper calls pv magazine Australia from Canada, to talk tech.
The best radiative cooling tech for PV arrays
Scientists in China have analysed the radiative cooling techniques used in combination with solar energy systems such as PV arrays, solar thermal collectors, and concentrated PV installations. They identified five major system typologies based on functionality and working time.
Sunday read: Too big to handle
There has been a flurry of activity within the PV cell manufacturer landscape over the past 12 to 18 months, and it’s largely been in one direction: bigger. But as large-format modules arrive on the market, questions are being raised as to how long the trend can continue and when bigger becomes, quite simply, too big.
Saturday read: Age of green hydrogen causes co-location rethink
The regions where the desert meets the sea have long been thought the most desolate and unproductive areas of the world, fruitful solely for those clever cultures who call them home. However, in the 21st century, that fiscal notion is turning on its head, and turning as rapidly as a wind turbine in a tornado, making harsh regions like Western Australia a verified paradise.
