500kW Rooftop System Powers Supermarket in Papua New Guinea

Hello everyone! Today we are at the port side of Papua New Guinea, showcasing a 500kW solar power plant meticulously designed by TANFON for a supermarket client. As you can see, we have installed a total of 800 solar panels on its roof, with each panel rated at 650W, and you can also check out the wiring connections we have made here. All the panels are properly grounded, and all cables are neatly placed in this cable tray to ensure safety and durability. Below, on the first floor, we have installed a containerized 500kW energy storage system, which includes the 500kW MPPT, an inverter with a custom-designed transformer, and a 1MW lithium battery pack to power the entire supermarket 24 hours a day, with the main loads being air conditioners and lifts. Today is December 1, 2025, and at this moment, the system is stably outputting 208.7kW of clean electricity while the client’s real-time load is only 192.6kW, meaning the client is operating entirely on solar power, achieving true energy self-sufficiency with zero grid power consumption. This is not accidental; data analysis shows the system configuration precisely matches and fully covers the client’s electricity needs, a result of TANFON engineers’ professional analysis and precise calculations to create a truly efficient and cost-effective optimized solution. And this long-term stability relies on TANFON’s professional operation and maintenance team, which provides 24/7 monitoring, early warning, and rapid response, offering the strongest guarantee for the long-term return on your green investment.
