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.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.

Finland

The state of Finland’s solar market

Anybody can easily assume that solar is not a feasible option in Finland because of Northern Europe’s climatic conditions. Surprisingly, the country is keen to develop its solar capacity albeit the less favorable climatic challenges. Over the last couple of years, the Finnish government has been working to build its renewable energy capacity. So, that is the current state of Finland’s solar market?

Well, the latest statistics reveal that Finland had an installed solar capacity of 214 Megawatts by the end of 2019. Residential installations account for 45% of the cumulative installed capacity and the rest is distributed amongst commercial and industrial installations. According to recent statistics, solar is the second least costly option for electricity generation. This is the primary reason for the solar market’s continued growth.

Currently, the Finnish solar market is ripe with opportunities for solar installers and other photovoltaic professionals. Are you one of them? If the answer is yes, you stand a chance of reaping big in Finland with a little determination and unrivaled expertise.

Solar equipment production and supply capacity in Finland

Generally speaking, Finland is a net-importer of solar equipment. Solar installers and other photovoltaic professionals mostly import equipment from Asian markets. Nevertheless, there is some module manufacturing capacity in Finland. Solarfeeds has got you covered if you need a reliable supplier that can meet your project needs.

Essentially speaking, we connect you to leading solar equipment suppliers. All you need to do is go to our inquiry page and send us a request for quotes. That is pretty convenient and time-saving, right?

Major Ports and logistics services in Finland

As I mentioned earlier, Finland is largely a net-importer of solar equipment. The country’s advanced ports and reliable logistics and forwarding services often simplify the importation process. Here are some seaports that are you should know;

•  Port of Hamina
•  Port of Jakobstad
•  Port of Helsinki
•  Port of Oulu
•  Port of Imatra
•  Port of Rauma
•  Port of Mustola
•  Port of Kristinestad
