20KW off-grid solar power system in Bangladesh on the border post, in Tajikistan.

The border post between Tajikistan and Bangladesh has long been troubled by power supply issues. The traditional power grid makes it difficult to cover this remote area. Relying on diesel-powered generators is not only costly but also unstable. Frequent fuel transportation is time-consuming and labor-intensive, and it is vulnerable to adverse weather conditions. To ensure the normal operation of the border post and enhance border security capabilities, introducing a reliable renewable energy power supply solution is urgent.

After extensive research and evaluation, a 20KW off-grid solar power system was selected. The system is equipped with high-efficiency solar panels that can generate electricity stably under different lighting conditions. The intelligent inverter can efficiently convert the direct current generated by the solar panels into alternating current to meet the power demands of various equipment at the border post. Meanwhile, a large-capacity energy storage battery pack ensures that the power supply remains uninterrupted at night or during inclement weather.

The installation team carried out the work in a complex geographical environment and changeable climate. They overcame difficulties such as rugged terrain and inconvenient transportation. They carefully selected the installation sites of the solar panels to ensure the best lighting angles. When connecting the inverter and the energy storage batteries, they strictly adhered to electrical safety standards to ensure the stable operation of the system.

After the system was put into use, the results were remarkable. The lighting, communication equipment, and monitoring systems at the border post can operate stably, free from the troubles of power shortages. The stable operation of the communication equipment strengthens the communication between the border post and the rear command center. The continuous power supply of the monitoring system enables real-time monitoring of border dynamics, greatly enhancing border security control capabilities. Moreover, compared with diesel-powered generation, solar power generation significantly reduces costs and is more convenient to maintain. The successful application of this 20KW off-grid solar power system provides a reference example for energy supply in other remote areas.
