Solar Market Outlook in Poland
Poland is considered as the solar market to watch in Europe. Needless to say, solar energy is becoming increasingly popular and in demand in Poland and it continues to boom.
The Institute for Renewable Energy in Poland reports that the country is experiencing a developmental boom in terms of the PV market. In fact, this country is the first one in the European Union based on the PV power growth rate, especially based on cumulative annual growth rate.
From 2016 to 2020, the growth rate of the solar power market is 114% (the EU average is only 10.3%). The PV market growth in Poland for 2020 nearly landed it in the top 10 in the world (it was ranked at 13).
The rapid growth of solar power in Poland puts it at 3.9 GW capacity as of 2021. It puts the country right on track to achieve its goal of 7.8 GW in solar capacity by 2025.
Based on the existing data and forecast trends, experts agree that Poland will hit 46% in annual solar capacity by 2024. This growth will be supported by the drop in prices of renewable energy in the country along with distributed energy technologies.
Solar Energy Equipment Supply Capacity in Poland
There is a huge array of options for solar power equipment suppliers and distributors in or outside of Poland. This makes it easy for residential and industrial installations of solar energy possible.
It is also part of the reason why there is a significant developmental boom in the country’s solar market.
Top 8 Major Seaports & Logistics in Poland
Poland has a thriving maritime port industry making it efficient for logistics company to handle goods and equipment in and out of Poland. The Port of Gdynia is the main seaport in Poland but there are a few other options too such as: Darlowo, Hel, Świnoujście, Władysławowo, Kołobrzeg, Gdansk, and Poznan.
Series Voltage Regulators
Series Voltage Regulators
When it comes to electrical works, a linear regulator is crucial as it is a system used to maintain the constant amount of voltage being generated. This regulating device is responsible for functioning as a ‘variable resistor’ that manages the voltage divider to maintain a constant voltage output while constantly disintegrating the input and regulated voltage. However, take note that there are many different types of voltage regulators to fit the type of your electrical needs. One of these is the linear regulators that come into two basic forms, they are shunt regulators and series regulators.
In today’s article, we will discuss what a series regulator is and its difference from the other type.
What is Voltage Regulator?
Series regulator or series pass voltage regulator is the more common form of a linear regulator. Compared to the shunt regulator, this one is more efficient since it can drop the voltage difference between the input and the required stabilized voltage while the shunt draws the current that is not needed by the load to maintain its voltage. Also, a series voltage regulator usually only sources the (supply) current, unlike shunt regulators.
The advantage of the series voltage regulator is that the amount of current drawn is effective than used by the load, although some will be consumed by any circuitry associated with the regulator. Unlike the shunt voltage regulator, the series regulator does not draw the full current even when the load does not require any current. As a result, the series voltage regulator is considerably more efficient.
How do Series Regulators work?
Generally, the series regulators work by setting a path from the supply voltage to the load through a variable resistor. Usually, a series pass transistor is used. It is located in the top half of the voltage divider, whereas the bottom half is the load. The series regulator uses a variable element placed in the series together with the load. Once the resistance of the series element changes, the voltage drop across it can be varied to make sure that the voltage across the load stays constant.
Usually, for more efficiency and to reduce stress on the pass transistor, manufacturers minimize its voltage drop. However, not all circuits regulate well once the input voltage meets the required output voltage halfway. Those that can do it are termed, Low Dropout regulators.
Series Voltage Regulator Cost
With a $20 budget on hand, you can start purchasing the cheapest but reasonably basic voltage regulators. The regulators ranging to this price typically require a manual setup in a DC setup, making it time-consuming to install. Whereas, the average cost of many linear voltage regulators ranges from $30 to $50. They are usually very basic, but you may find them either in AC or DC setups. If you look for higher prices, you will find some really expensive products. Usually, these regulators are equipped with advanced technology, making them more durable, easy to set up, and have precise regulators.
Conclusion: Is it Worth it to Purchase Series Voltage Regulators?
Series voltage regulators have the advantages of simplicity and convenience. Not to mention that their output does not cause switching spikes that you can usually see on some switch mode supplies. However, these regulators have relatively lower efficiency levels than the switch-mode power supply. Good thing, manufacturers keep on improving their performance and functionality.
