Solar Power Is Booming in Emerging Markets

Solar energy is going gangbusters. The world is adding photovoltaic solar panels at a blistering rate, shattering its own records year after year, buoyed by a flood of ever-cheaper solar panels out of China. “We have a plentiful and cheap source of electricity that can be built quickly, almost anywhere in the world,” NewScientist wrote in an article published late last year. “Is it fanciful to imagine that solar could one day power everything?”But the growth of solar power is uneven around the globe, with some regions seeing a rapid transformation while others see their numbers plateauing. Interestingly, it is some of the world’s poorest countries that are now leading the solar revolution, while some of the richest and most avid champions of the clean energy transition are lagging behind.“Europe likes to think of itself as a champion of renewable energy, the Economist wrote in an August report, when in reality, solar additions in 2025 barely topped those of 2024, and in 2026 “new deployments are set to fall in every big EU country except Italy.”Set OilPrice.com as a preferred source in Google here.Europe’s solar slowdown is in large part thanks to the constraints of the continent’s energy grid. During peak production hours, the grid is overly congested and lacks sufficient energy storage, leading to energy wastage, negative energy prices, and even the threat of grid failure and catastrophic blackouts, such as the one that took almost all of Spain and Portugal offline in 2025. European leaders are racing to add storage capacity to the grid in order to address these mounting issues and avoid yet another energy crisis, but in the meantime, adding even more solar to the overloaded grid will only serve to intensify these issues.But one dark horse country managed to stay ahead of the curve when it comes to energy storage development, and is therefore now emerging as a surprise solar frontrunner in 2026. “Unlike many western European countries, Romania is deploying storage relatively early in its solar build-out, rather than trying to catch up after large amounts of solar capacity have already been installed,” Antonio Arruebo, an analyst at SolarPower Europe, told the Economist. Much of this growth comes in the form of small-scale and residential solar-plus-battery systems. As a result of the steady growth of these much smaller capacity additions, Romania managed to see a 45 percent increase in solar installations in 2025, while the rest of Europe barely eked out any growth at all.“At the start of Europe’s solar revolution, the impulse was to get panels deployed by all means. As the industry matures, countries need to strike a balance between generating capacity and storage,” the Economist writes. “Romania looks like a model.”But Romania is not alone in this approach – nor in its success. Around the globe, some of the world’s poorest countries are seeing unprecedented gains in solar energy capacity growth thanks to solar-plus-battery systems. In recent years, emerging economies including Brazil, Chile, El Salvador, Morocco, Kenya, and Namibia have all overtaken the United States – the world’s largest economy – in their clean energy transitions.“Some countries are pulling off stunningly fast energy transitions, adding solar so rapidly, it’s become a major source of electricity over the course of years — not decades,” reports CNN. Pakistan has become the surprise poster child of this movement over the past couple of years as residents install rooftop solar and batteries faster than any other market on Earth. Pakistanis are rapidly adopting these systems to provide electricity more cheaply and reliably than the country’s beleaguered energy infrastructure.Globally, solar power adoption is no longer a matter of climate policy – it’s going gangbusters thanks to its essential and growing contribution to energy security and simple economics. Solar is now the cheapest form of energy on Earth, while also representing the clearest pathway forward to energy autonomy and resilience, especially for smaller and growing economies that need to shield themselves from the whipsaw geopolitical climate in which they have vanishingly little leverage.By Haley Zaremba for Oilprice.comMore Top Reads From Oilprice.comRussia Doubles Dark Fleet to Ship LNG to AsiaU.S. Energy Storage Capacity Installations Hit Record High in Q2Asia Spot LNG Prices Hit 5-Month High as Hormuz Blockage Drags On
