4.505kWp Solar Power System in Bunyip Victoria
This solar Power system was installed on a home in Bunyip, Victoria, which is under the Ausnet Distribution zone. Ausnet usually limit solar installations to under 4.6kWp per phase, and if a customer wishes to install a bigger system, an application fee of $220 is applied, usually with a resulting rejection. So when in the Ausnet area, we design systems under the 4.6kWp threshold, per phase. This Q.Cells solar installation was coupled with a Schneider inverter, and mounted on a colorbond roof. As you can see from the photo, we have isolated each string with a DC isolator, which is protected by the elements with a customized Green Power aluminium cover plate. This will protect the isolators and enclosures from degrading, and ensure the longest life possible.
The most common cause of failures in a solar power system is degradation of exposed electrical DC breakers, which can short out the system and even cause fire from arcing. This is why we use high quality 1500V DC breaker from Yager & Benedict (Austria), and we always include an aluminium protection cover plate.
Another major cause of failure with solar power systems, is the inverter. Most companies generally install the cheapest inverter possible, which will possible last 5 years, but not much longer. We recommend using high quality, proven inverters from companies such as Schneider Electric. Coupled with quality panels from QCells, and you will have a solar power system that will works for 25+ years with a minimum chance of failure or issues.
