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 […]

Solar Power Purchase Agreements

Solar Power Purchase Agreements (PPAs) are a financing model that has the potential to transition those operating as suppliers of energy-generating equipment to the role of the more traditional energy retailer. This transition will see solar installers mature commercially to become solar developers. PPAs have been around for many years and are widely used in […]

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. […]

Potential Induced Degradation (PID)

Potential Induced Degradation (PID) is a process that occurs in photovoltaic (PV) cells when the system has a negative potential relative to the ground. As a result, the PV module’s efficiency decreases over time. Although PID is a relatively new concept and is not widely understood, techniques already exist to minimise its undesirable effects. The […]
