Australia’s Solar Energy

The utilization of energy created by the heat and light of the sun and converting it into electricity is commonly known as Solar Power Energy. It was in the 1860’s when solar power technologies was first developed, arising from the distress of industrialist that the current coal, oil and fossil fuels supply would become scarce and limited. Thus, becoming more costly for individual households to afford.

The growing concern has then led to the re-evaluation and re-assessment of the international energy policies and regulations. According to the 2018 World Economy Outlook published by the Organization for Economic Co-operation and Development and the International Energy Agency, the global demand for energy increased by 2.1% in 2017 with a 398 GW of solar PV installed around the world, and, meeting the 2% of global electricity demand.

In which, the rate of installations are influenced by changes, alterations and updates in the policy mechanisms supporting such technology. Nonetheless, this trend is expected to significantly increase in numbers by another 25% by the year 2040.

As one of the fastest developing countries, the land down under has relied greatly on solar power energy as their preferred energy source for decades now. However, it was only then in the year 2015 when the age of solar power technology in Australia underwent a rapid growth. The increasing cost of energy resources like fossil fuels, has led to a significant number of households that are turning into solar energy.

The emergence of government funded incentive programs for the incorporation of domestic and commercial solar power utilization also proliferated. Through the years, solar-powered technology has become Australia’s optimal energy source.

Geographically speaking, the Australian continent is known to have the highest solar radiation per square meter of any continent with an average of 58 million petajoules (PJ) of solar radiation per year, which is approximately 10,000 times larger than the country’s total energy consumption. This has helped increase Australia’s Gross Domestic Product (GDP) to $275 million for every petajoule of energy consumed.

To date, there are 2.15 million or 21% of Australian households are recorded to have Solar Photovoltaic (also known as solar PV) with a combined capacity of over 12.9 gigawatts installed on their rooftops that directly converts sunlight into electricity using a semiconductor cell or solar PV cell. This type of solar power technology is the most common and widely used in households.

Wholesale Shunt Regulator for PV Systems

Essentially, a shunt regulator — also known as a shunt voltage regulator (aka. charge controller)— is a form of regulator where the regulating element shunts the current to ground. By maintaining a constant voltage across its terminals, it takes up the surplus current to maintain the voltage across the load.

In terms of the basic operation of a shunt regulator, the load is operated with a resistor in series with the voltage source and the shunt regulator in parallel with the load. In order to keep the voltage across the load constant, a level of current must be drawn through the series resistor to maintain the required voltage across the load. The load will take some, and the remaining current is drawn by the shunt voltage regulator.

The circuit is designed so that at maximum load current, the shunt regulator draws virtually no current, and at minimum load current, the shunt voltage regulator passes the full current. As a result, it can be seen that shunt regulators are inefficient because the maximum current is drawn from the source regardless of the load current, i.e. when there is no load current.

Because of the purpose of the shunt regulator, this device has been considered as an essential element within the linear power supply technology.

Zener Diode Shunt Charge Controller

One of the most common and simple forms of shunt regulator is the simple Zener diode regulator circuit.

Its mechanism is very straightforward. Once over its small minimum current, the Zener diode maintains an almost constant voltage across its terminals. The series resistor drops the voltage from the source to the Zener diode and loads. As the Zener diode maintains its voltage, any variations in load current do not affect the voltage across the Zener diode. It takes up the current variations required to ensure the correct drop across the series resistor. In this way, it shunts sufficient current to maintain the voltage across its terminals and hence the load.

In the shunt voltage regulator circuit, the Zener diode must be capable of dissipating the power from the maximum amount of current it can handle. This is most likely to be a little more than the maximum current supplied to the load as the Zener diode will need to pass all the current when the load current is zero. Therefore, the total maximum current that will be passed by the diode is the load current plus an allowance for current to maintain the reference voltage when the load is taking its maximum current.

It should also be noted that for the shunt regulator circuit, the series resistance is comprised of the series resistor value, plus any source resistance. In most cases, the value of the series resistor will dominate and the source resistance can be ignored — but this may not always be true.
