Pak's quiet solar rush puts pressure on 'national grid'

Pakistanis are increasingly ditching the national grid in favour of solar power, prompting a boom in rooftop panels and spooking a government weighed down by billions of dollars of power sector debt.

The quiet energy revolution has spread from wealthy neighbourhoods to middleand lower-income households as customers look to escape soaring electricity bills and prolonged power cuts.

Down a cramped alley in Pakistan's megacity of Karachi, residents fighting the sweltering summer heat gather in Fareeda Saleem's modest home for something they never experienced before — uninterrupted power.

"Solar makes life easier, but it's a hard choice for people like us," she says of the installation cost.

Saleem was cut from the grid last year for refusing to pay her bills in protest over enduring 18-hour power cuts.

A widow and mother of two disabled children, she sold her jewellery - a prized possession for women in Pakistan - and borrowed money from relatives to buy two solar panels, a solar inverter and battery to store energy, for Rs180.000 ($630).

As temperatures pass 40°C, children duck under Saleem's door and gather around the breeze of her fan.

Mounted on poles above homes, solar panels have become a common sight across the country of 240 million people, with the installation cost typically recovered within two to five years.
