Here are India's top ten solar states

These account for almost 90% of all solar installations and pipeline.

Mercom Capital Group revealed in a recent report that India has a total installed large-scale solar capacity of 9,018 MW and a solar pipeline of 14,030 MW as of December 2016, with the top 10 states accounting for approximately 90 percent of all solar installations and pipeline. 

These states including, Tamil Nadu, Rajasthan, Gujarat, Andhra Pradesh, Telangana, Madhya Pradesh, Punjab, Karnataka, Maharashtra and Uttar Pradesh hold the key to India’s solar future.

Tamil Nadu leads all other Indian states with 1,577 MW in-operations. In order to fulfil the state Renewable Purchase Obligation (RPO) the Tami Nadu Generation and Distribution Company (TANGEDCO) recently auctioned 500 MW solar. The state has close to 485 MW of solar under various stages of development.

Here's more from Mercom Capital Group:

Rajasthan’s position was recently usurped by Tamil Nadu as installation activity in the state has slowed. The state has 1,324 MW of solar in-operation with a project pipeline of ~1,206 MW and could reclaim the top spot.

Considering Gujarat has large tracts of land ideal for large-scale grid-connected solar projects and hasn’t faced evacuation and transmission issues, the solar sector in the state has been stagnant with ~1,101 MW in-operation and 300 MW under development. Gujarat is a power surplus state and has met its RPO obligations and is not in a hurry to ramp up its solar installations.

Andhra Pradesh is the state with the most solar parks. Activity in solar sector has picked up in the state with the completion of Kurnool solar park. At present, Andhra Pradesh has solar projects aggregating 1,009 MW in-operation and 1,494 MW under development.

Telangana has come a long way with its solar policies and programs since its inception as a state. These programs have helped the state leapfrog others to claim the fifth spot with 1,006 MW in-operation and 2,418 MW under development.

Madhya Pradesh has transformed itself from a power deficient state to a power surplus state. Rapid implementation of policies and programs has led to a growing solar sector. Currently, the state has 861 MW in-operation and 722 MW under various stages of development.

The infrastructure at the Rewa solar park is nearly complete; once tenders are issued, solar is expected to pick up pace.

The largely agricultural state of Punjab has shown progress in terms of fulfilling its power demand. Punjab is ranked seventh with projects in-operation aggregating 569 MW. The state has a project pipeline of ~453 MW.

Karnataka has the largest solar project pipeline of ~3,376 MW. The state is facing solar park issues relating to evacuation and transmission which could delay projects. The state is ranked eighth with projects in-operation aggregating ~511 MW.

Maharashtra, the most industrialized state in India, is ranked ninth in terms of solar energy production. Projects aggregating ~384 MW are in-operation. The state has a project pipeline of 957 MW.

Uttar Pradesh is a surprise addition, after power purchase agreements (PPAs) in Jharkhand for 1.1 GW were not signed. The development of solar in Uttar Pradesh has been slow; the state has in-operation projects aggregating 241 MW and a project pipeline of 696 MW.
