Chinese-made photovoltaic panels cost 12 cents a watt in 2026, down from $5-$6 at the turn of the millennium, and that price collapse is now powering rooftop solar installations from Pakistani cement plants to Philippine homes and Australian suburbs, according to the Financial Times. A Pakistani cement giant has cut its power costs by up to 40% with solar at its production sites, and rooftop solar capacity in the Philippines has nearly doubled in a year. At the same time, Africa is on pace to install record gigawatts, and Australia has installed panels on more than 4 million homes. Previously, we reported that India is on track to become the first country ever to industrialize using solar energy instead of fossil fuels such as coal and oil, thanks to rapidly falling solar costs, generous government subsidies and favorable geographic factors. Last year, India added a record-breaking 44 GW of solar power, taking its installed solar capacity to 154 gigawatts with projections that solar will meet half of the country’s electricity demand growth through 2030. However, India is hardly the only country that’s betting big on solar. The wide availability of cheap Chinese photovoltaic panels is fueling the rapid rise of small-scale, individual power generation for homes, businesses and factories across the globe, in both developed and emerging economies.

Pakistan's Bestway Cement Limited, one of the country's largest cement manufacturers, is deploying ground-mounted solar farms across five production units to cut its reliance on Pakistan's unstable power grid. At its Chakwal plant, 26 MW of installed photovoltaic capacity already generates over a quarter of the electricity powering the facility.
“It’s the only way we can compete,” says Abdul Waheed, GM at the Chakwal plant, according to the Financial Times. “Our rivals have already gone in this direction.” The Chakwal facility produces over 3 million tonnes of cement per year.
Distributed solar is seeing major growth in regions where power is scarce, unreliable or expensive. Ember estimates that rooftop solar capacity in Philippines almost doubled over the 12 months to April, with residential solar panels now able to pay for themselves in just over three years. Meralco, the country’s electricity distributor, estimates that rooftop solar in the Philippines generated 372 gigawatt hours in the first half of 2026 alone.
Likewise, Ember projects that Africa is on track to install a record 17 gigawatts (GW) of solar capacity in 2026, good for a robust 45% Y/Y increase, with about three-quarters of this growth driven by distributed, small-scale systems on commercial and industrial rooftops.
Decentralized solar is proving to be a major hit in India, too. Launched in February 2024, India's government-sponsored rooftop solar program has put panels on more than 5.5 million homes and is adding roughly 500,000 more each month. With an initial budget of roughly $9 billion, the scheme transfers Central Financial Assistance (CFA) directly into the homeowner's bank account within 30 to 45 days of inspection, based on installed capacity, and the government has partnered with banks to offer collateral-free, low-interest loans covering part of the installation cost for lower-income families. The program also uses net metering, letting homes sell excess solar power back to the grid.
But developed countries are also benefiting, as we’ve seen with Australia, which currently leads the world in rooftop solar adoption, thanks to an overabundance of sunshine, high electricity costs and strong government incentives. Over 4.3 million homes and small businesses in the country (~43% of total) have solar panels, making it the highest per-capita adoption rate worldwide and double the runner-up and nearly 10 times the global average. Australia’s total rooftop solar capacity recently reached 28.3 GW, outstripping the country's coal-powered generation, which stands at roughly 22.5 GW. However, such a high level of solar adoption can also lead to major grid instabilities, as Australia is now finding out.
Meanwhile, plug-and-play solar (aka balcony solar or plug-in solar), has become a big thing in Europe. These panels allow users to generate electricity by mounting a small panel and plugging a microinverter directly into a standard household wall socket. Great Britain officially legalized plug-in solar systems in August this year, permitting a maximum AC output of 800W connecting directly to standard wall sockets.
