Abstract: India has ambitious solar energy targets of 100 GW by 2022, including 60 GW at large-scale solar and 40 GW at small-scale solar. While India has made considerable progress in meeting these targets, with 22 GW of solar deployment in 2018, it has a long way to go. Given that solar deployment in India is now largely driven by states, this study strives to understand state-level drivers for solar deployment in India, so as to inform future policy making for reaching India's solar targets. Using econometric techniques – a time series cross sectional regression with fixed effects – over a panel dataset over 11 years (2009–2019) of Indian states, it explores policy, economic, and structural drivers of solar deployment. The key results indicate the importance of two policies – the Renewable Purchase Obligations and Solar Parks – in reaching India's solar target. It may be postulated that these learnings would also be useful for other developing countries with significant solar ambitions. Further, while no further evidence of policy effectiveness is found, more results are expected to emerge as access to more and better data becomes available.
