GreenYellow has announced a deal to install 38 MWp of solar capacity across 54 Carrefour stores in Brazil. The projects will be built under power purchase agreements, meaning Carrefour buys the electricity generated without upfront capital costs. This is a good example of how commercial and industrial solar is scaling in Latin America, where retail chains are using rooftop and parking lot space to cut electricity costs and reduce emissions. The 38 MWp spread across 54 sites averages about 700 kWp per store, which is a practical size for large-format retail. Brazil has strong solar irradiance and a growing distributed generation market, so these installations should deliver solid returns. The key question is how fast GreenYellow can get these systems connected to the grid, as interconnection delays have been a bottleneck in other markets. For those tracking corporate renewable procurement, this deal shows that PPAs are becoming the standard mechanism for retail decarbonization in emerging economies. It also highlights the role of specialized developers like GreenYellow who handle permitting, installation, and maintenance for clients that do not want to manage energy assets directly.
