Mexico has quietly assembled a solar revolution on its rooftops. By the end of 2025, distributed solar installations across the country had reached 5.165 gigawatts of capacity — a milestone that represents not just megawatts and engineering, but a fundamental shift in how millions of Mexicans produce their own energy.
The scale of this transformation is staggering. Across 600,368 separate installations, Mexicans have invested more than $13 billion in small-scale solar systems. These aren't sprawling utility plants; they're rooftop panels on homes and small businesses, each one a piece of energy independence. The National Energy Commission found that among all small-scale power systems under 0.7 MW in capacity, 99.5 percent are solar — an overwhelming endorsement of the technology's appeal to ordinary Mexicans.
The engine driving this surge is Mexico's net metering policy, a deceptively simple rule that has unleashed entrepreneurship and investment across the country. Under net metering, rooftop solar owners are paid for excess electricity they send back into the grid. The results speak for themselves: 593,607 applications for net-metered systems have been approved, accounting for 5,113.14 MW of installed capacity. The policy has democratized solar power, making it accessible not just to large corporations but to families and small business owners who can recoup their investment over time.
The breakdown reveals how accessible these systems have become. Systems of up to 50 kilowatts represent 98.23 percent of all net-metered applications and contribute 3,251.46 MW of capacity — the heart of Mexico's rooftop solar movement. These are the systems most Mexicans can actually afford and maintain. Yet larger installations, though far fewer in number, punch above their weight: systems between 250 and 500 kilowatts make up just 0.40 percent of applications but deliver 989.02 MW, or nearly one-fifth of all net-metered capacity. This mix shows how renewable energy is working at every scale of the economy.
The western state of Jalisco has emerged as Mexico's distributed solar leader, hosting nearly 100,000 installations that generate 747.67 MW of power. It's worth pausing on that number: one state, one policy, one technology — nearly 100,000 Mexicans deciding to power their homes and businesses with the sun. The momentum is undeniable.
What makes this milestone genuinely hopeful is that it happened not through government mandates or dramatic policy shifts, but through a simple economic truth: when people can save money and earn income from solar, they choose it. Net metering aligned financial incentive with environmental benefit. The result is a grassroots energy transition happening across Mexico, from rooftops in Jalisco to installations in hundreds of municipalities nationwide. Five gigawatts of distributed solar power represents billions of kilowatt-hours of clean electricity that will flow into Mexican homes and businesses for decades. It's also a proof of concept that the fastest path to renewable energy adoption isn't always top-down — sometimes it's rooftop by rooftop, family by family, choice by choice.
