A brief look at New Zealand’s solar market

Unlike most economies worldwide, New Zealand boasts of colossal renewable energy penetration. Currently, renewables account for 90% of the nation’s total energy consumption. Despite the high degree of renewable energy utilization, solar generation in New Zealand is still at its lowest.

The most recent solar capacity statistics reveal that New Zealand’s grid-connected solar energy stands at 159 Megawatts. This figure is pretty low, considering that the country’s solar potential is 11 Gigawatts. Nevertheless, things are looking up for New Zealand’s solar market due to new solar-centered initiatives.

In December 2020, the government of New Zealand launched a Green Investment finance facility worth US $69 million. Based on this development, forecast studies reveal that solar penetration could reach 9.3 % by 2050, up from 0.2% in 2020. Essentially, New Zealand could have an installed capacity of 300 Megawatts in 2025 and I.1 Gigawatts by 2030. Logically, many projects will have to be implemented to achieve these targets. This will generate opportunities for solar installers and professionals in New Zealand’s solar market.

New Zealand’s solar equipment supply capability

New Zealand has several solar equipment suppliers focusing on different equipment categories, including solar panels, solar water pumps, and charge controllers. Nevertheless, there is a big possibility that you will not find what you need, especially when dealing with large-scale projects. Still, there is a simple solution in such a scenario.

Solarfeeds.com grants you access to 50 solar equipment categories. Kindly visit our inquiry page and place a request. You will receive free quotes in record-breaking time. Also, you don’t have to worry about importation modalities because New Zealand boasts of a healthy network of ports and logistical support frameworks.

Shunt Regulators

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.
