El-Salvador

Solar Market Outlook in El Salvador

Despite being the smallest country in Central America, El Salvador is one of the strongest proponents of renewable energy production in the region. This is part of the government’s commitment to reduce emissions and to increase energy efficiency while utilizing the country’s tropical climate. The hot and humid weather, along with the high rate of sunshine per year, makes it the best location to utilize solar energy and other renewable energy sources. The average daily solar radiation in El Salvador is measured at 5 kWh/m2.

The National Energy Policy mandate in El Salvador has helped to boost its renewable energy production. Currently, it accounts for over 60% of the country’s energy production, although solar sources only contribute to 4% of that.

This is set to change in the coming years, though, as El Salvador is focused on increasing its solar PV installation capacity. They have helped increase PV generation capacity through auctions since 2014. Still, it cannot be denied that the solar market in El Salvador is still in the nascent stage and the government is looking at investment incentives and other policies to encourage development of solar PV. 

Solar Energy Equipment Supply Capacity in El Salvador

There is currently a limited amount of domestic investments on solar generation plants in El Salvador. However, there are plenty of global suppliers and distributors that can be tapped at the moment for those looking to make solar installations.

Major Seaports & Logistics in El Salvador

The Port of Acajutla is the primary seaport in El Salvador that facilitates the handling and logistics of solar equipment and other goods (both import and export). This makes it convenient for anyone looking to order from top suppliers for solar installations. 

In addition to this, there are other smaller ports like Port of La Union and Port of La Libertad

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.
