Recently, Bridge to India, a renewable energy consultancy in India, said it had cut its forecast of solar rooftop growth in India to 2021 from 13.2 GW to 10.8 GW.
Bridge to India, a knowledge services provider in renewable energy in India, has released the latest version of its infotainment said that, "Rooftop Solar Map of India."
According to the information, in the 12 months to September 2017, India added 840 MW of rooftop solar capacity with an annual growth rate of 82%. As of September 2017, the cumulative installed capacity was 1,861MW.
The data also emphasizes that business and industrial consumers remain the largest areas, accounting for 63% of total capacity and 66% of new capacity in the past 12 months. During this period, capacity in this area increased by 86%.
Vinay Rustagi, managing director of Bridge to India, said in a map release: "Roofing solar is growing rapidly and debt and equity financing are now moving more freely, but the 40GW by March 2022 is still very unrealistic.
Despite the government's strong mandate and 25% subsidy, the government is particularly disappointed with the slowdown in capacity growth in the public domain.
The data notes that CleanMax, Cleantech Solar and Amplus are clear leaders in the operating project development category. Delta and SMA maintain their dominance in the inverter market. The data also said that Tata Power Solar is still the largest EPC contractor in rooftop solar.
The residential roof solar market has been growing at a steady 45%. However, the biggest disappointment comes from the low profit margins in the public domain. In the past 12 months, the actual increase was only 173 MW, although only 200 MW was forecast.
Bridge to India Modified Estimated new installed capacity of 887 MW in 2017, 28% below previous forecast.
Rustagi added: "We have revised our projections for the next five years to total 10.8 GW by 2021, 18% less than previously forecast."
The data also pointed out that Maharashtra has replaced Tamil Nadu as India's largest rooftop solar state.
