“The local-content policies are good policies, but we have to ask to what level it can be taken and we have to think differently about distributed generation,” Rodolfo Pinto, chief executive of Engie Solar's Brazilian arm said during a panel on new business models for rooftop solar at the Brasil Solar Power conference in Rio de Janeiro.

Engie Solar recently bought control of a local installer as it tries to tap into the growing rooftop market.
