New Accreditation Administrator Announced – Everything we know about Solar Accreditation Australia

The Clean Energy Regulator has just announced Solar Accreditation Australia (SAA) as the new installer and designer accreditation administrator! This means that the CEC is no longer the accreditation scheme operator, and the SAA accreditation scheme is now in effect. SAA is an independent, not-for-profit organisation founded by the Smart Energy Council and Masters Electricians […]

Solar Installation: Common Mistakes and Best Practices

In 2023 the Clean Energy Council suspended 166 accreditations and cancelled 51. Most of the cases opened came from the Clean Energy Regulator’s inspections program [1] which focuses on quality and compliance of installations across the country. GSES has been part of the Clean Energy Regulator’s inspection program for many years and has seen all […]

NSW Work Health & Safety Amendment Bill 2023

Last month, the NSW parliament passed the WHS Amendment Bill 2023. The bill covers a number of updates in relation to increased maximum penalties, a new silica register and a new asbestos notice regime.  The changes primarily impact PCBUs (Persons Conducting a Business or Undertaking), as PCBUs are responsible for providing and maintaining a working […]

AS/NZS 4777.2 2020 Updates – What You Need to Know

The 2020 updates to the inverter Standard AS/NZS 4777.2 Grid connection of energy systems via inverters, Part 2: Inverter Requirements is now available. If you’re a solar professional, you’re probably familiar with the 2015 version of the Standard. In December 2020, the Standard was updated to reflect changing conditions in the industry. These changes could […]

Specialised Cable Sizing of Complex Electrical Circuits

Cable sizing and derating are critical elements in any electrical project, not just solar power installations. Most electricians rely on Australian/New Zealand Standards AS/NZS 3008.1.1 and AS/NZS 3000 to provide the answers necessary to adequately size and derate cables for a given load in any situation. In some scenarios, a specific site or installation may […]

DC Cable Sizing using AS/NZS 3008; and Limitations

This article will give you an overview and examples of DC cable sizing using the standard AS/NZS 3008. Cable sizing is one of the most crucial engineering problems in PV system design. It has major implications on the overall cost, performance, and safety in design of PV systems. Correct cable selection also ensures compliance with Australian […]

Why do we need to derate electrical cables?

This article will look at the physics behind why it is necessary to derate electrical cables. It is the first in a series of articles covering cable sizing and deratings, so stay tuned for more on different methods to derate cables safely while maintaining cost effectiveness. Cable selection is one of the most crucial engineering problems […]

Implementing Virtual Power Plants (VPP) in Australia

Virtual power plants (VPP) have the potential to make the grid infrastructure more resilient in Australia. Currently, VPPs can reduce the pressure on the grid during times of high demand. It does this by linking small-scale independent decentralised generators like PV systems and batteries into a network, with communication and controls to allow the units […]

Effect of Orientation and Latitude on the Performance of Solar Tracking Arrays

A solar module generates maximum power when the surface of the module directly faces the sun. For a stationary module facing the equator, this typically occurs during the middle of the day. The high performance of solar tracking arrays comes from the ability to maintain the optimum angle for a longer period of time. The […]
