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.

Vietnam

 Vietnam’s Solar Market Outlook

Vietnam, a developing country in Southeastern Asia, has seen a dramatic increase in energy demand in the last five years.  This rise in demand has subsequently fuelled the growth of the solar sector in the swiftly developing Asian country.  According to recent International Renewable Energy Agency (IRENA) statistics, Vietnam is among the top ten leading countries in solar utilization. This is pretty awesome for a developing nation, don’t you agree?

Statistics released in late 2020 reveal that Vietnam’s solar capacity stood at over 7.4 Gigawatts. This is positively surprising considering that the country’s solar capacity was only 4 megawatts in 2015.  The figure below will help paint a clear picture of Vietnam’s exponential growth in matters concerning solar energy;

Solar equipment supply capacity in Vietnam

From a solar products production and supply perspective, Vietnam has immense growth potential.  As part of an ambitious solar sector growth plan, the government of Vietnam has implemented flexible investment policies. These policies are primarily responsible for the rise in domestic and foreign producers and distributors dealing with different solar product categories.

It is also worth mentioning that Vietnam’s incredible port and logistical infrastructure have further strengthened its positive solar sector outlook. As stated by the World Economic Forum, Vietnam ranks at position 80 on the quality of port infrastructure. Do you intend to sell or buy solar products from the Vietnamese market? If the answer is yes, you can rest assured that you can safely transport any product to or from Vietnam.

I can confidently conclude that there are immense opportunities for individuals who intend to buy or supply different solar products in Vietnam.
