South Korea

An in-depth look at South Korea’s solar market

South Korea is a forward-thinking economy situated in the Asian continent. It is also amongst the top ten electricity consumers in the world. What portion of the nation’s energy consumption is solar?

South Korea’s solar market has been performing pretty well in recent years. According to the country’s trade ministry, approximately 4.1 Gigawatts of photovoltaic systems were installed in 2020. Any solar installer or solar industry professional will agree that this is an outstanding achievement.

It is also essential to note that South Korea’s solar capacity has been on an upward trajectory since 2018.

In 2018, the nation’s solar capacity stood at 2.4 Gigawatts and 3.8 Gigawatts. Essentially, 2020 was the most successful year recorded by South Korea’s solar market. Still, the solar market is headed for a boom as the country looks to the future.

Opportunities for solar installers and professionals and in South Korea’s solar market

Are you a solar expert or solar professional pursuing success in your field? There are vast opportunities for you in South Korea’s solar market. It would be unjust if I failed to tell you that this is the best time to work in South Korea.

Investment in South Korea’s solar market will be approximately $5.1 billion in 2021; only 3.8 Gigawatts of solar plants are expected to secure funding. You could be one of the individuals working on these projects if you play your cards right.

It is also worth noting that South Korea boasts of several solar equipment producers and distributors. In addition to that, it has a healthy network of ports and logistical infrastructure. Therefore, you can easily import any equipment that may not be available locally. Solarfeeds, a leading e-commerce marketplace for solar equipment, is here for you. Feel free to visit our inquiry page and post a quote request. We will get back to you promptly because we value you.

Grid Tie Inverters

Buy Wholesale Grid-Tie Inverters for PV Systems? 

Simply put, a grid-tie inverter converts direct current (DC) into alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panels, wind turbines, hydroelectric, and the grid.  To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately match the voltage and phase of the grid sine wave AC waveform. 

How Does a Grid-Tie Inverter Operate?

Grid-tie inverters convert DC electrical power into AC power that is suitable for injecting into the electric utility company grid. In order to achieve this, the inverter must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant.  A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1 degree of the AC power grid. Additionally, the inverter has an onboard computer that senses the current AC grid waveform and outputs a voltage to correspond with the grid. However, supplying reactive power to the grid might be necessary to keep the voltage in the local grid inside allowed limitations. Otherwise, in a grid segment, with considerable power from renewable sources, voltage levels might rise too much at times of high production (i.e. around noon for solar panels).  Furthermore, grid-tie inverters are also designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that in the event of a blackout, the grid-tie inverter shuts down to prevent the energy it transfers from harming any line workers who are sent to fix the power grid. 

 Types of Grid-Tie Inverters

Grid-tie inverters include conventional low-frequency types with transformer coupling, newer high-frequency types, also with transformer coupling, and transformerless types. Instead of converting direct current directly into AC suitable for the grid, high-frequency transformer types use a computer process to convert the power to a high-frequency and then back to DC and then to the final AC output voltage suitable for the grid.  Meanwhile, transformerless inverters, which are popular in Europe, are lighter, smaller, and more efficient than inverters with transformers. However, that said, transformerless inverters have been slow to enter the U.S. market because of concerns that transformerless inverters, which do not have galvanic isolation between the DC side and grid, could inject dangerous DC voltages and currents into the grid under fault conditions.
