As part of its commitment to advancing the clean energy transition, PT Medco Power Indonesia continues to drive innovation in renewable energy development. One such initiative is the adoption of bifacial solar photovoltaic (PV) technology at the East Bali Solar Power Plant (PLTS Bali Timur) a breakthrough that significantly enhances efficiency and power generation compared to conventional solar panels.
Unlike conventional (monofacial) panels that capture sunlight from only one side, bifacial technology enables energy generation from both the front and rear surfaces. In addition to direct solar irradiance, these panels harness reflected light from surrounding surfaces, allowing for increased energy production without requiring significant additional land.
To optimize system performance, the implementation of bifacial technology at PLTS Bali Timur is further supported by the use of solar trackers and whitesheets. Solar trackers enable the panels to follow the sun’s movement throughout the day, maximizing solar irradiance capture. Meanwhile, whitesheets reflective ground layers enhance surface reflectivity, enabling the rear side of bifacial panels to capture more reflected light.
One of the key advantages of this technology is its ability to increase energy output. In general, bifacial systems can deliver an additional 5% to 10% energy yield, and potentially more depending on site conditions and system design. This improvement not only enhances plant performance but also contributes to lowering the Levelized Cost of Energy (LCOE), thereby improving overall project economics.
To achieve optimal performance, several critical factors are carefully considered in the implementation of bifacial technology. These include ground surface reflectivity, which influences the amount of light reflected to the rear side of the panels; panel spacing and installation height, which affect light intensity; and overall system design and configuration, including tilt angles and layout. All of these aspects have been carefully considered in the development of the East Bali Solar Power Plant to ensure maximum performance.
Through the adoption of bifacial solar PV technology, PLTS Bali Timur not only increases energy production capacity but also optimizes the use of available resources. This initiative reflects Medco Power’s commitment to delivering more efficient, sustainable, and competitive energy solutions.
Looking ahead, such innovations will continue to play a key role in Medco Power’s transformation journey, strengthening its renewable energy portfolio while supporting national decarbonization efforts.
