A global study has found that India is the most cost-effective country for generating rooftop solar energy at USD 66 per megawatt-hour, while the cost in China is marginally higher at USD 68 per megawatt-hour.
Due to the lower cost, rooftop solar photovoltaics (RTSPV) technology, such as roof-mounted solar panels used in homes, and commercial and industrial buildings, is currently the fastest deployable energy generation technology. This, according to this global study, is projected to fulfil up to 49% of the global electricity demand by 2050.
