Pakistan’s growing embrace of solar power is reshaping both agriculture and energy consumption, but concerns are emerging over its long-term consequences for water resources and state finances. In Punjab province, farmers have shifted rapidly from diesel or grid-powered tube wells to solar pumps, making it easier to irrigate fields more frequently. The change has encouraged the expansion of water-intensive crops such as rice, a trend that analysts warn could worsen groundwater depletion in a region already facing mounting water stress.
Reports from Reuters indicate that farmer Karamat Ali sold his livestock to purchase solar panels and now irrigates fields with ease, something previously unaffordable due to high energy costs. According to the US Department of Agriculture, rice fields in Pakistan grew by 30 percent between 2023 and 2025, while maize cultivation fell by 10 percent. Economist Ammar Habib highlighted that around 650,000 tube wells now operate on solar, up from a fraction just a few years ago. The rapid adoption has been driven by an 80 percent collapse in solar panel prices since 2017, largely due to Chinese production. However, Punjab’s water authority has reported a sharp increase in groundwater stress, with areas where levels drop below 60 feet rising by 25 percent since 2020, while deeper zones beyond 80 feet have more than doubled. Farmers admit they now irrigate multiple times a day, compared to once daily before, since solar energy eliminates the cost constraints that diesel and electricity imposed.
Experts, including the World Bank, have cautioned that without strong regulation and effective monitoring, the unchecked solarization of irrigation could lead to a severe water crisis. While Punjab’s irrigation minister admitted that clean energy adoption is contributing to declining water tables, the federal power minister rejected the claim, creating a split in official views. Authorities have attempted to address the issue through canal rehabilitation projects and experimental aquifer recharge initiatives, yet gaps in real-time monitoring and governance remain significant. The lack of a comprehensive framework risks accelerating the overuse of groundwater at the same time that Pakistan faces rising climate challenges.
Alongside the environmental strain, Pakistan’s solar surge is complicating the country’s energy sector finances. Bloomberg reports that the spread of rooftop solar is reducing electricity demand from state-run utilities, undermining a system where the government purchases power from producers and sells it to consumers. Falling revenues threaten to worsen the financial strain of “capacity payments,” in which utilities must pay independent power producers regardless of actual sales. This could increase tariffs for non-solar users and deepen public dissatisfaction. The fiscal burden is further complicated by heavy borrowing from foreign creditors, including China, and by Pakistan’s ongoing negotiations with the International Monetary Fund over reforms in the energy sector.
The paradox facing Pakistan is that solar power is offering households and farmers relief from rising costs while promoting clean energy use. However, without integrated planning to manage water use and stabilize fiscal policies, the rapid expansion of solar risks creating new challenges for the economy and environment.
