Nepal

 A breakdown of Nepal’s solar market

Nepal, a mountainous landlocked nation between China and India, has struggled with power shortages for several years. The country relies heavily on hydroelectric power, which, frankly, is not sufficient to serve the electricity needs. Consequently, the government is looking to exploit the nation’s solar potential to remedy the situation.

Nepal can potentially harness 2,920 Gigawatts per annum by utilizing 0.01% of its total land area. Thanks to Prime Commercial Bank’s solar financing efforts, this solar capacity target may become a reality sooner than you can imagine. As a result of the bank’s support, the government completed its first solar project in February 2021.

The project will add 10 Megawatts of energy to the nation’s power grid. Due to the success of Nepal’s initial solar project, the government plans to execute approximately 300 Megawatts of solar projects soon. This means that solar installers and professionals should expect vast opportunities in Nepal’s solar market soon.  

Nepal’s solar equipment supply capacity

Even though Nepal’s solar market is at its initial stages of development, it boasts of 80 solar equipment distribution companies. Nepal’s supply chain’s leading solar equipment categories include solar panels, inverters, batteries, and solar water heaters. Nevertheless, equipment sales in Nepal are currently limited to individual households.

Still, you don’t need to worry if you need equipment for a large-scale solar project. Nepal has several ports that facilitate direct shipping of solar equipment from established solar markets such as China and the USA. Solarfeeds.com, a leading e-commerce marketplace, grants you access to leading solar equipment brands worldwide. Visit our website’s inquiry page and request a quote for your project. I guarantee that Solarfeeds offers the best deals when it comes to solar equipment.

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.
