Sineng Electric is powering up its 1.6 GW solar project in Inner Mongolia, China after supplying 854 MW string inverters to the solar farm. The high-efficiency string inverters will convert direct current (DC) from the solar panels to alternating current (AC) for grid supply. The latest announcement on Sineng Electric’s 1.6 GW Solar Project in China is not just for clean energy transition. It will also underscore the region’s efforts towards environmental sustainability. Project factsheet Developer: Sineng Electric Location: Inner Mongolia, China Cost: 6.973 billion RMB ($960 million) Capacity: 1.6 GW (Gigawatts) Solar farm area: 7,347 acres String inverter units: 2,671 SP-350K-H1 String inverter operating power: 1,500 V (Volts) Annual electricity production: 3.155 billion kWh (Kilowatt-hour) Estimated annual revenue yield: 725 million RMB ($99 million) Sineng’s 1.6 GW Solar Project in Inner Mongolia, China The 6.973 billion RMB ($960 million) 1.6 GW Solar Project in Inner Mongolia spans more than 7,300 acres of land – carpeted with solar panels. Now operational, the solar farm in expected to produce more than 3 billion kWh of clean energy per year. Upon connecting to the grid via the 2,671 high-efficiency string inverters provided by Sineng, an annual revenue of more than 700 million RMB ($99 million) is expected from power sales every year. This is a massive boost for the country’s economy; parallel to the large investment made to the Sineng Electric’s 1.6 GW Solar Project in Inner Mongolia, China. The anti-PID string inverters for the solar farm The 2,671 SP-350K-H1string inverters are nothing short of efficient. Operating at 1,500 V, they will convert the energy generated by the photovoltaic (PV) panels on the 1.6 GW solar farm to a voltage and frequency supported by Mongolia’s electricity grid. Being of modular design, the series-arranged string inverters are considerably cheap and require minimal maintenance. Another exciting feature in the design is that if one fails, the rest of the system remains operational. According to Sineng Electric, the string inverters for the 1.6 GW solar farm in Inner Mongolia also feature 1.1 times overloading capacity, anti-PID and PID recovery capabilities. What is Potential-Induced Degradation (PID)? Potential-Induced Degradation (PID) happens when PV panels voltage drop due to current leaks. This causes loss of power output, and is more likely to happen due to a high negative voltage potential between the panels and the grounded system. The anti-PID prevents this, while the recovery feature helps minimizes the effects of this event in the unfortunate circumstance PID occurs. |
