The rooftop solar system cooperation between Tona Syntegra Solar (TSS) and the Norwegian Renewable Energy investor is deployed at 10 BigC (Go!) supermarkets across Vietnam. Including 6 in the North and 4 in the South, with the capacity up to 6740.82 kWp and 4267.65 kWp respectively.


Built during the Covid pandemic 19 and was heavily impacted by the Government’s Lockdown and Social Distancing, the project was beautifully constructed and handed it over to the owner within 24 weeks (from May 2021 to November 2021) while not impacting and interrupting the activities underneath. The project also combines all types of metal (trapezoidal, seam lock) and concrete roofs with strict requirements from the owner and the FM global standards.


The systems are among the most complex solar power systems in Vietnam. When empowered by the most modern technologies such as Inverter Shutdown, Zero Export Control, and Sensor System, which help control and protect the system, ensure safety in fire prevention and fire fighting,


With a nationwide supermarket chain, BigC (Go!) is one of the largest consumer retail chains in Vietnam. TSS expected that rooftop solar system at 6 northern supermarkets will produce an average of 7663.6 MWh and reduce 4335.3 tons of CO2 per year; while 4 Southern supermarkets will produce 6356.1 MWh and reduce 3535.6 tons of CO2.
