Various generous feed-in tariff (FiT) schemes, including NSW’s 60c Solar Bonus Scheme, will come to an end on the 31st December 2016. It is estimated that over 275, 000 households in Australia will be affected by these changes to feed-in tariffs. For PV system owners in states other than NSW, feed-in tariff rates will be […]

To maintain our position as the preferred knowledge network for the industry and commerce of renewable energy innovation & technology, GSES communicates factual, up-to-date and evidence based information for publication. These include information on the issues surrounding DC circuit breakers, earthing fundamentals, how to sell solar, and information on isolator enclosures.
Battery Charging on AC Coupled Grid Connected Battery Systems
The advent of Grid Connected Battery (GCB) systems in Australia has led to increased interest in coupling GCB systems with existing or new solar PV system to increase energy self-sufficiency. GCB systems can be connected to a PV system as a DC coupled system, where the PV array is connected through a charge controller directly […]
A Practical Guide to PV Efficiency
At the end of June 2016, the world record for efficiency of rooftop solar modules was broken again: the US-based PV manufacturing company SunPower achieved an efficiency of 24.1% for a monocrystalline silicon-based PV panel, over 2% higher than the previous record. This news came shortly after the announcement earlier in the month of Hanwha […]
Residential energy storage: Are we ready?
The rise of residential batteries In the past year we have seen the first significant uptake of Grid Connected Battery (GCB) systems in Australia. In years gone by, batteries were used for standalone systems that were far from any poles and wires, i.e. in areas with no access to the electricity grid. However, we now […]
Configuring Battery Storage Products – Comparing Apples and Oranges?
The renewables market is currently being flooded with energy storage products to meet the increasing demand and hype for this technology. All of these products present a similar, well-scripted value proposition and all offer to deliver similar functionality. As a result, this rapid rush to market of these products and their advertising has created the […]
Standalone: Past, Present and Future
Stand Alone Photovoltaic (PV) systems are amongst the oldest of applications of photovoltaic systems and are a testament to photovoltaic technology’s ability to operate in the most extreme of conditions. They are typically used in isolated locations with low or no population, or in place of conventional grid infrastructure in less-developed regions. Standalone systems, as […]
Micro Inverters vs DC Optimisers: An Australian Installer’s Perspective
In many ways the rapid uptake of PV in Australia over the last decade has caused the city-based PV installer a problem: many of the easy, large area, unobstructed, north-facing roofs have already been used. Often this leaves us with “sub-optimal” installation options involving small areas where only 1-4 modules will fit, roof areas that […]
The Use of Variable speed drives with solar water pumping systems
The use of solar photovoltaics (PV) technology as an alternative to traditional energy sources such as petrol and diesel generators to power electric water pumps has become increasingly apparent. Solar PV technology is used extensively by remote villages and farmers as the power source to pump water for domestic consumption, sanitation, livestock and irrigation. A […]
Big solar’s ascendancy as coal slips in the popularity stakes. How ready is the Australian solar industry?
The Adani-owned Carmichael mega-mine inches ever so slowly towards a final approval amid falling coal prices and fierce community opposition. At the same time Adani has recently expressed interest in solar farms in South Australia and Queensland. What will the growth of Australia’s large scale solar sector be set to experience? The large scale solar […]
PV System Design: How to compete effectively in the wider market place
Commercial-scale PV systems present enormous opportunities for our industry. However, the requirements to source and verify a range of site-specific data over a large site is challenging. To then ensure this data correctly forms part of all aspects of the system’s performance and installation requirements can be complicated and unfamiliar to some system designers and […]
