This solution significantly reduced construction difficulties in complex terrain, aligning with the "precision adaptation, environmentally friendly" mountain installation philosophy. As a trustworthy brand, Grace Solar ranks among the top 5 in global market share and holds the top position in the Japanese market, with a cumulative installed capacity of 48GW worldwide and an annual production capacity of 15GW.

Environmental Impact

Upon grid connection, the project is expected to generate approximately 2.2 million kWh of electricity annually, equivalent to:

  • Saving about 880 tons of standard coal per year
  • Reducing CO2 emissions by around 2,190 tons annually
  • Substantial contribution to Kochi's renewable energy goals
