Over the last ten years, solar energy systems in Australia have become more popular as the cost of renewable energy has dropped significantly. According to several reports, in 2020-21, Australia generated around 10% of its electricity from solar PV, which is the fastest-growing power source.  

 

What are Stand Alone Power Systems? 

Stand-alone PV systems generate electricity to charge batteries in the daytime. This electricity can then be used during the night when the sun is not available for power. A stand-alone PV system is a form of sustainable energy that utilises rechargeable batteries as a power storage system. 

 

One or more photovoltaic cells, conductors, electrical components, and one or more loads make up a stand-alone photovoltaic (PV) system. For residential applications, the PV system is not required to be installed on a roof but can be used on vehicles, boats, tents, and wherever there is a need for remote power.  

 

Stand-alone PV systems work well in remote rural areas, especially when other power sources are inaccessible or unavailable to power lights, appliances, etc. As a result, installing a single stand-alone PV system is more economical than having the local company provide power directly into the home via grid-connected PV systems. 

 

In addition to being among the oldest photovoltaic applications, stand-alone photovoltaic systems are a demonstration of the power of the technology to withstand harsh conditions. A variety of energy sources can be used in these systems, including hydroelectric, solar power, wind, and fossil fuels, and most include energy storage systems.  

 

In Australia, stand-alone PVs were used for telephones and repeaters in rural areas in the 1970s. As solar panels became more affordable, the telecommunications industry expanded nationwide. In the late 2000s, stand-alone PV became evident as a viable option for several situations, such as parking lots, energy-intensive industries, and emergency response equipment. 

 

Important Factors in a Stand-Alone PV System 

To make an excellent decision, one must carefully consider and plan. Solar panels are no different.  

To begin with, it is important that you pay attention to how and when you consume electricity. Because the sun is the only source of electricity for solar panels, it is crucial to generate and save enough electricity even for the days when the weather is not in your favour. If you have solar electricity, it’s hard to imagine not having it, although you don’t want to misuse it! In addition to reducing your electric consumption, purchasing energy-saving appliances will enable you to install a smaller PV system. You can start small with energy efficiency and add on as your needs grow. 

 

Secondly, despite the ease of installation and operation of stand-alone PV systems compared to other off-grid power technologies such as windmills, hydropower, etc., solar PV systems must be maintained regularly, which is not necessary with grid-connected mains power. But make sure you know how your stand-alone solar power system works and how to maintain it. 

To make sure that the system is running optimally, it needs regular maintenance. Like many other off-grid systems, PV systems require some electrical expertise to install and maintain, as well as troubleshoot problems as they arise. 

 

Although a stand-alone PV system, being a renewable energy technology, has several advantages: low maintenance, no waste, and the ability to expand by adding additional panels and batteries, there are some disadvantages. Like high initial costs, solar power dependence, and possible health risks related to battery acid and fumes. 

 

With an increase in the demand for sustainable energy as an alternative to power consumption, the need for Stand-Alone Power Systems is growing. But still, it’s equally important to gain insight into how they work and their efficiency.  

 

Which is the best way to understand how the system works? It is PMV. Therefore, Stand Alone Power Systems – Design & Install by Project Management Vision (PMV) comes in. During studying the renewable energy courses, you will acquire skills and knowledge related to Stand Alone Power systems, which will enable you to analyse information, create tailored solutions, and communicate the results of these solutions with clients. 

 

Upon completion of the current version of the following Units of Competency, a Statement of Attainment will be issued: 

  • UEERE0025: Perform basic repairs on renewable energy devices
  • UEERE0035: Install a stand-alone photovoltaic power system
  • UEERE0022: Identify and solve problems in photovoltaic energy apparatuses and systems
  • UEERE0031: Design a stand-alone renewable energy system
  • UEERE0046: Resolve problems related to stand-alone renewable energy systems

An off-grid SPS combines solar energy, battery energy, and generator power into a single power source, and the users rely on the SPS 100% of the time. Normally, power loss caused by a nuisance trip or by any component failure would be very frustrating for the end-user.  

 

Therefore, a professional system design and installation requires competency and significant knowledge about the renewable energy courses. As a niche training provider, Project Management Vision (PMV) excels at delivering competency-based training of renewable energy courses in accordance with AS/NZS and IEC standards.
