The power sources most familiar for the supply of renewable energy – wind, sun and water – are considered to be freely available; therefore a common assumption is that the energy provided by these power sources is also free. A stand-alone power system (SAPS), in order to take advantage of ‘free’ energy sources, costs money […]

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.
Residential Demand Charges – What is it, and can solar and battery storage help?
With the impending closure of Hazelwood and the Prime Minister’s talk of ‘clean coal’, attention on electricity prices in 2017 has so far centred around the effect coal-fired stations have on the cost of electricity. The introduction of a new tariff charge by some utilities which have directly affected some customers from 1st January 2017, […]
Industry wide Improvement in Ingress Protection Safety Thanks to CEC Guidelines
Under the Renewable Energy Target (RET) requirements, solar photovoltaic (PV) power systems must be installed to relevant Australian standards and Clean Energy Council (CEC) guidelines in order to receive Small-scale Technology Certificates (STCs). To monitor this, the Clean Energy Regulator’s RET inspection program has been running since 2010 and the CEC review the outcomes of […]
The Blockchain Buzz
Over the past several months, there has been an increase in the amount of reference to Blockchain technology and what it can do for the renewable energy sector. Much has been written about this technology such as this article and this article. A number of global companies have even started to trial blockchain based energy […]
Building Integrated Photovoltaics: What is the potential for this PV technology?
Building Integrated Photovoltaics (BIPV), as the name suggests, describe a PV system where solar PV modules are integrated within a building’s envelope, as oppose to conventional PV systems where modules are mounted on the top of existing roofs. BIPV products have been commercially available since the 1990s in Europe, but have not played a major […]
The Duck Curve – the duck hunting season we want to have
The power blackout in South Australia in September 2016 produced numerous ‘experts’ to analyse the causes of this event. The Australian press, politicians, shock-jocks and the public all had their particular slant to apply when assessing why this catastrophic failure occurred. GSES thought it opportune to provide some contextualised background to how distributed renewable generation, […]
Connection of Inverter Energy Systems to the Grid: New requirements surround residual current devices
The industry has seen rapid uptake of solar PV and energy storage systems connected to multiple mode, or ‘hybrid’, inverters and battery systems over recent months. This has prompted many questions from installers and designers regarding the connection of inverter energy systems to existing electrical installations. While many common questions regarding connecting IES systems can […]
Battery Storage Systems: What are their chemical hazards?
While consumer interest in battery storage systems continues, an issue often overlooked when discussing the pros and cons of battery storage systems is the chemical hazards associated with the battery technology and ways of managing these hazards. An array of battery chemistries is available on the commercial market, and the range of products continues to […]
Generous Feed-in-tariff Schemes: their demise and what information is useful for affected system owners?
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 […]
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 […]
