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.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

Taiwan, Province of China

Solar Market Outlook in Taiwan

The Taiwanese solar energy sector is one of the rapidly growing industries in Asia. In 2021, it is targeting to achieve a growth of 1.5 to 1.7 GW of solar capacity. In order to meet this target growth rate, the Taiwanese government is accelerating its development efforts for the coming year. 

The government of Taiwan is currently promoting its PV policy while also building construction timelines for ground-mounted projects. There are two areas that the Taiwanese solar PV market is focusing on: fishery-solar hybrid power stations and major electricity consumers. If plans push through, Taiwan is looking at a solar market future with a green energy certification scheme and feed-in tariff scheme in place. 

The government of Taiwan took serious steps toward the start of its switch to solar and wind power at the start of 2020. However, it is still a long way to go before it can mitigate any losses incurred from the shutdown of coal plants. With the renewed focus on solar energy, the government expects that reliance on coal for energy production will drop from 44% to 37% in 2030. The economic leaders in Taiwan have previously set the target of 20 GW in solar energy production by 2025, although solar project managers are doubtful that they can hit this target. 

Solar Energy Equipment Supply Capacity in Taiwan

Taiwan currently has a shortage of local solar equipment suppliers and manufacturers. However, there are several global suppliers and distributors to increase its solar installation capacity.
