The island of Ta'u in American Samoa is home to around 600 people. Located in the southern Pacific Ocean, the island relied until recently on diesel generators for energy production — which meant that not only did the generators produce pollution as a byproduct, but the diesel itself had to be shipped in at a rate of around 300 gallons per day. SolarCity, a company just acquired by Tesla, took a year to set up the island with a bank of solar panels and Tesla Powerpack industrial-grade battery energy storage that means Ta'u now runs almost entirely off the sun.

Scientists at The Australian National University (ANU) have set a world record for efficiency for a solar thermal dish generating steam that could be used for power stations.

The team designed and built a new receiver for the solar concentrator dish at ANU, halving losses and achieving a 97 per cent conversion of sunlight into steam. The breakthrough could lead to the generation of cheaper base-load electricity from renewable energy and help lower carbon emissions which cause global warming.

The atomic fallout in Chernobyl, Ukraine was one of the worst nuclear disasters in history and put around 2600 square kilometres of land out of commission. It's been good for bad horror films and for the wildlife that has blossomed there following the disaster, but after decades of people unable to return to their homes and the property surrounding the reactor abandoned, it was only a matter of time before somebody wanted to attempt to reuse it.

A new variant of the Toyota Prius has been launched in Japan, with the plug-in hybrid having its internal rechargeable battery also boosted externally by a set of solar cells on the sedan's roof. It's an option for both Japanese and US buyers, but we won't get it in Australia in the foreseeable future.

Redflow's new ZCell home battery, launched in March, is a 10 kilowatt hour (kWh) flow battery that can 'timeshift' solar power from day to night, store off-peak power for peak demand periods and support off-grid systems.

Redflow have now been able to fully integrate the ZCell battery with energy storage management provider Redback Technologies Smart Hybrid Solar Inverter System, which manages energy supplies from the grid, PV solar panels and a battery.

CSIRO today unveiled a solar-powered air-conditioning system to cool Australian commercial buildings, achieving greater energy efficiency.

Operating at Stockland Wendouree Shopping Centre in Ballarat, Victoria, the system uses concentrating solar thermal technology to produce heat energy used to power the air conditioning system.

Some 1.4 million of Australia's 7.8 million homes — around one in five — currently have solar power. During the day, solar panels generate large volumes of power that go unused in the home. This unused energy is exported to utilities who pay around 7c per kilowatt hour. At night, when families are home, power usage increases, and families purchase energy at four times their generation rate, with basic flat tariffs ranging between 25 to 28c per kilowatt hour.

Brisbane-based Redback Technologies is launching a second generation version of their smart hybrid inverter and a new family of grid tied inverters that the solar energy specialist says will help households and commercial users increase the percentage of solar power they self-consume, improving the pay back from solar panels and helping to reduce reliance on fossil based fuels.

Online reviews can make or break a business, especially in a competitive field like solar power installations. While asking customers to review your business is fine, giving them incentives to make them positive definitely is not.

Following an investigation by the Australian Competition and Consumer Commission (ACCC), solar retailer True Value Solar has ceased offering its customers incentives for publishing positive online reviews.
