Bhutan's rooftop solar development presents significant potential opportunities and technical advantages due to several factors: (i) the country benefits from a good solar irradiance of more than 2,000 kWh per meter square per year, indicating favorable solar energy availability; (ii) most roofs in Bhutan have not been utilized for other purposes, providing ample space for solar installations without major obstacles; (iii) issues related to land acquisitions, environmental and social impacts are expected to be minimal, making the rooftop solar implementation immediately feasible; and (iv) no additional investment is required to connect to the grid as the distribution network in Bhutan has sufficient capacity to accommodate.
