India added more rooftop solar power last year than the previous 4 years combined

A boy dusts off a solar panel installed on the rooftop of his house on the outskirts of the western Indian city of Ahmedabad October 27, 2014. Factories and businesses have installed over 30 MW of rooftop solar panels in the last year, data compiled by New Delhi-based consultancy Bridge To India shows. That is a small amount compared with India's solar capacity of 2,700 MW, but demand may accelerate under Prime Minister Narendra Modi who has made renewable energy a priority. Bridge to India forecasts compound annual growth will hit more than 60 percent in the next five years, as falling panel prices make installations more alluring.

India increased its rooftop solar power capacity in 2017 by more than the previous four years combined, according to a new report from Bloomberg New Energy Finance. The country added 715 megawatts in rooftop photovoltaic (PV) power in 2017, contributing to a compound annual growth rate of 117% since 2013.

The expansion has gone hand in hand with a steady decline in the price of rooftop solar panels. Prices have been cut in half over the past five years, thanks to mass production, fierce competition and advances in technology. In contrast, average retail electricity prices have increased by 22% during the same period.

Solar rooftop panels are the fastest growing sub-sector of the renewables market in India. But the wider market is also showing some impressive growth.

Installation of renewable energy projects will be higher than fossil fuel technologies for the first time in 2017, and is projected to be so for the years ahead. In total, the country added 12 gigawatts of renewable energy plants in the last financial year (from April 2016 to March 2017), representing 66% growth on the previous year.

Rural electrification is a key part of the Indian government's plan to boost the economy. About 300 million of India's 1.3 billion people are still not connected to the electricity distribution grid.

Kerosene lamps are commonly used in the rural locations, and these are bad for the environment as well as being hazardous around the home.

Prime Minister Narendra Modi has promised to meet these electrification goals by installing record amounts of renewable energy.

In 2014, Modi set a target to increase India's solar power capacity to 100 gigawatts by 2022 – 40% of which is to be from rooftop solar. So despite the fast expansion, there is still a great deal of capacity to add before that target is achieved.

But even aiming for such ambitious targets will undoubtedly contribute to the world’s efforts to meet the goals set by the Paris climate agreement, and possibly inspire other countries to start solar power revolutions of their own.
