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 […]

I got 99 problems but a switch ain’t one (ONLY VALID UNTIL DATE OF PUBLISHED)
Correct isolator selection and installation is an extremely important aspect of ensuring PV systems are safe and up to standard. Through the extensive inspection work that GSES has conducted, and feedback from industry, interpreting isolator data sheets can be tricky for many installers. In response to this GSES has increased its focus on isolator selection […]
East West Arrays: Are they worth it?
The current cost of rooftop PV means that it can be cheaper to source your electricity from a rooftop solar system than buy it from the grid. A significant problem with this, however, is that people consume 50%+ of their electricity during the morning and evening when solar systems are not producing, is it possible […]
Power Factor and Grid-Connected PV
As the level of Grid-Connected PV penetration continues to rise, the importance of power factor and power factor correction is going to become increasingly relevant both from the perspective of the grid and the customer. This article explains what power factor is, what it is caused by, its impact on the grid, and how GridConnected […]
PV Training challenges & how they affect installations
Since being established in 1998, GSES has focused on assisting the growth of Australian and international PV industries by providing quality training. GSES is recognised for its expertise in providing the training required for grid-connected PV design and install accreditation. In training many electricians and engineers, GSES has identified certain areas that prove to be […]
Oversizing PV Arrays
‘Array oversizing’ refers to solar photovoltaic (PV) systems that have been designed so that the solar array has a higher peak capacity than the inverter. A solar system of a given installed capacity under irradiance consistent with Standard Test Conditions, may actually deliver up to 20% less than the nameplate rating of the solar array. […]
