SARAL has been designed collaboratively by the Ministry of New and Renewable Energy (MNRE), Shakti Sustainable Energy Foundation (SSEF), Associated Chambers of Commerce and Industry of India (ASSOCHAM) and Ernst & Young (EY).

• Karnataka has been placed at the first rank in the Index that evaluates Indian states based on their attractiveness for rooftop development.
• Telangana, Gujarat and Andhra Pradesh have got 2nd, 3rd and 4th rank respectively.
• SARAL currently captures five key aspects – 

1. robustness of policy framework
2. implementation environment
3. investment climate
4. consumer experience
5. business ecosystem

• It encourages each state to assess the initiatives taken so far, and what it can do to improve its solar rooftop ecosystem.

• This will help states to channelize investments that can eventually help the sector grow. 
• In addition, such an exercise is likely to create a more conducive environment for solar rooftop installations, encourage investment and lead to accelerated growth of the sector.

The Ministry of New and Renewable Energy (MNRE) has set a target of 175 GW of renewable energy capacity by 2022, of which 100 GW solar power is to be operational by March 2022, of which 40 GW is expected to come from grid connected solar rooftops.
