Pakistan: the solar revolution nobody planned

The fastest distributed-solar rollout in the world happened almost entirely by accident.

Jun 07, 2026

Pakistan imported more Chinese solar panels than any other country on earth in 2025 (except for the Netherlands through the port of Rotterdam but destined for across the EU). No subsidy programme drove it. No national rooftop scheme. No feed-in tariff. People just did it.

The satellite image below shows the scale of change in a powerful way: Same rooftops in 2021 and 2025. Within the matter of 3 years rooftop solar has grown exponentially now visible from space (using Google Earth images).

We are used to energy transitions that happen because governments engineer them, with incentives and mandates and targets. Pakistan’s solar boom is the opposite. It is probably the fastest deployments of distributed solar anywhere in the world, and it happened largely in spite of the state rather than because of it. But Pakistan is also a cautionary tale for what happens in an unmanaged transition and by no means is this a blueprint for other countries to follow. But it shows just how rapidly solar can be deployed around the world.

An important note: I am NOT a Pakistan energy expert and this is very much someone looking in from the outside from high altitude. I hope that I got most of what I write here right but appreciate feedback and will include nuance where it is needed.

The numbers behind the story

Pakistan imported roughly 7.6 GW of solar panels in 2023, then 16.4 GW in 2024, then 16.9 GW in 2025. Around 55 GW have now arrived in total. That makes Pakistan the second-largest importer of solar panels in the world in 2025. Pakistan, a country of around 241 million people with a long history of power cuts, now absorbs a remarkable share of everything China’s solar industry makes.

And it is showing up in the grid data. By the summer of 2025, solar had become Pakistan's single largest source of electricity, generating around a quarter of the total during peak months. Official numbers understate the boom of solar because most of the panels were installed on rooftops and behind meters, in a distributed system no one is fully measuring.

Most of that hidden capacity is overwhelmingly residential. Of an estimated 33 GW of distributed solar, around half sits on the roofs of homes, with the rest split across industry, agriculture and commerce. Contrary to it being a story of big developers and utility contracts it is millions of households making the switch.

Why it happened

A key reason for the boom of solar in Pakistan is about resilience and grid reliability. Load-shedding, the scheduled rationing of power when supply cannot meet demand, has been a daily fact of life in Pakistan. How long the lights stay off depends on where you live, and the gap between a wealthy Islamabad suburb and rural Balochistan is enormous.

For years the outages were blamed on capacity shortages and not enough power stations. That was once true but it is not any more. Pakistan now runs a capacity surplus and in 2024 its power plants ran at barely a third of their capacity.

There is a long chain of interlinkages that exacerbate the problem of missing money as an excellent academic study analyses in great detail: Expensive imported fuel pushed generation costs up. Contracts with private producers guarantee them capacity payments whether their plants run or not, now around 2.5 trillion rupees a year for electricity that is often never generated. The public utilities cannot recover enough to cover those bills, so the debt piles up into a circular debt of close to 2 trillion rupees. Faced with that, the system rations supply, cutting power longest where losses are highest and bill payment is lowest.

Scheduled outages in April this year were permitted by the regulator for several hours a day - now a common feature in Pakistan. The distribution companies serving Islamabad and Karachi keep cuts to a handful of hours a day. In Sukkur and Quetta, rural customers can be without power for up to two-thirds of the day. The chart below shows the spread across the country’s main distribution companies, and the gulf between urban and rural service ( I could not get hold of the 2025 data yet but here is the April 2026 data).

To see how extreme this is, hold it against Europe and the US: In Europe, customers typically face around a few minutes of outages per year (both planned and unplanned). The average American, battered by hurricanes in 2024, lost about 11 hours over twelve months, and closer to two hours in a normal year. In some parts of Pakistan people can lose more than that before lunchtime. A household in Quetta can face 16 to 20 hours of outages in a single day. When that is the alternative, a roof full of panels and a battery offers energy resilience.

But not only outages drove solar demand. Electricity in Pakistan also became very expensive. The average effective tariff roughly tripled in a decade, from about 12.5 rupees per unit in 2015 to over 34 rupees in 2025. Pakistan’s power sector now carries a circular debt of close to 2 trillion rupees, the accumulated result of unpaid subsidies, under-recovery, and capacity payments owed to independent power producers for plants that often sit idle. Around 37% of a typical bill is now made up of surcharges tied to that debt.

So households and businesses were being asked to pay more and more for electricity that arrived unreliably, while watching the price of solar panels collapse. China’s manufacturing glut pushed module prices to record lows at exactly the moment Pakistani consumers were most desperate for an exit. A rooftop system could pay for itself in two to three years. For a factory facing industrial tariffs, the payback was faster still.

This is the engine of the boom Pakistan experienced. When grid power is expensive and unreliable, and the alternative is cheap and getting cheaper, people vote with their wallets.

The catch

A bottom-up solar revolution sounds like an unambiguously good news story. It partly is. But it also creates a genuine problem:

When the customers who can afford solar leave the grid, fewer kilowatt hours are consumed from the grid. But many of the high fixed costs remain. As a result, costs, including the capacity payments owed to idle power plants, get spread across a shrinking base of remaining customers. Their bills go up. That pushes more of them towards solar. Which shrinks the base again. This is the classic utility death spiral, and Pakistan is one of the clearest real-world examples of it now unfolding.

The government’s response tells you how seriously it takes the threat. In February 2026 the regulator, NEPRA, replaced the decade-old net metering regime with a new “net billing” system. Under the old rules, solar owners were credited for exported electricity at the same rate they paid for it. Under the new ones, utilities buy surplus solar at the national average purchase price of around 11 to 13 rupees per unit, while selling power back at the full retail rate of 40 to 55 rupees. Existing net-metering customers were eventually grandfathered in after a backlash, but the direction is clear: The regulator is trying to slow the exodus.

You can read this two ways, and both are true. It is a regressive move that makes solar less attractive and protects a failing centralised model. It is also a rational attempt to stop wealthier consumers from offloading the cost of the grid onto everyone who cannot afford to leave it. The regulator’s own projection is that without reform the losses would reach hundreds of billions of rupees over the next decade. The uncomfortable reality is that a transition this fast, and this unplanned, breaks things on the way through.

And there are equity concerns too. Solar adoption in Pakistan rises steeply with income. Wealthier households are far more likely to have already left, which is exactly why those still on the grid end up carrying more of its cost.

The bigger picture

Most of the world’s future electricity demand growth will come from countries that look more like Pakistan than like Germany. Hot, growing, energy-hungry, often saddled with creaking grids and expensive imported fuel. The conventional assumption was that these countries would electrify the way the rich world did, through large centralised power stations and slow grid expansion. Pakistan suggests another path is not only possible but may be unstoppable once the price signals line up.

The optimistic view is that a country that spent decades short of power has, in the space of three or four years, built one of the most solarised electricity systems in the developing world, funded overwhelmingly by private money. There is also another more positive side to this. Not everyone adding solar is leaving the grid; some are gaining access to electricity for the first time. According to the regulator, more than a quarter of Pakistanis had no grid connection in 2023. For these households, a panel and a small battery can provide power where the grid does not reach. The same cheap imports that let a factory cut its grid use also make it easier to electrify homes that were previously off-grid. Distributed solar, then, is not only a way for better-off consumers to exit the system. It can also help narrow Pakistan’s electricity access gap, provided the panels reach the households that need them most.

But Pakistan is also a warning. Solar deployment is the easy part now. The hard part is the system around it: the grid, the tariffs, the market design, the question of who pays for the shared infrastructure when generation becomes something millions of people own themselves. Pakistan ran ahead on deployment and left the institutions trailing. The result is a boom and a crisis happening at the same time, in the same place.

The lesson is not that distributed solar is dangerous. It is that policy has to keep pace with it. Solar will continue to be deployed in large numbers regardless. Whether it strengthens the existing system or hollows it out depends on choices that are being made now.
