Recent updates in the PV array installation standards and best practices have led to questions about the types of earthing and bonding in photovoltaic systems. This article aims to clarify what is meant then terms like earthing and bonding are… Read More »Understanding Earthing
Over the past decade the solar industry in Australia has transformed from a small collection of highly specialised companies to a booming industry where dedicated “sales teams” are required to manage the large volume of PV system purchases. Rapid growth… Read More »The Do’s and Don’ts of Selling Solar
Installing roof-top isolators is mandatory in Victoria and the ACT. It also is an increasingly common practice in other states as a way to enhance the safety of PV installations during maintenance and in emergency situations. However, installing isolators correctly… Read More »Isolator Enclosures: more than just a box
To understand why the required ratings are different depending on the type of inverter installed, and whether or not the array cables are earthed it is first necessary to understand what happens when a PV array is electrically connected to… Read More »Effect of Orientation and Latitude on the DC Circuit Breaker Sizing Requirements
1 Government regulations and policies MNRE has several incentives, including subsidies and rebates, for the installation of solar rooftop systems. In addition, some state governments have additional benefits for those installing solar systems.
