Fiji’s solar market status
Most Pacific Island countries spend vast chunks of their annual GDPs on fuel imports. This is illogical considering that there is no shortage of renewable sources of energy in the Pacific region. Is Fiji different from other Pacific states that are dependent on costly fossil fuels for their daily needs?
The most recent statistics concerning Fiji’s solar market reveal that the country has an installed solar capacity of 4 Megawatts. This meager solar capacity is a course for concern primarily because its solar potential is approximately 170 Gigawatt-hours annually. However, the government’s newfound desire to exploit the nation’s renewable energy potential offers something to smile about.
Fijian authorities are currently working on what could be the largest solar energy project in the pacific region. They plan to install at least 15 Megawatts of solar generation capacity with financial support from the International Financial Corporation. The success of this project is most likely to open up new opportunities for solar installers and professionals in the Fijian solar market.
Fijian solar market equipment supply capacity
Even though Fiji is an emerging solar market, it enjoys a good presence of solar equipment suppliers. Some readily available equipment in Fiji includes solar panels, batteries, inverters, and charge controllers. Nevertheless, these suppliers serve a small market and may not have the capacity to supply mega-project equipment. In such a scenario, the best course of action is importing equipment from leading brands in established solar markets.
Fiji’s Suva and Lautoka ports make it easy to import solar equipment from any leading solar equipment brands on Solarfeeds. We are the source of the most competitive equipment quotes in the global solar sector. The only thing you need to do is visit our inquiry page and send us a request.
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.
