Strung across 14 acres of a Los Angeles County thrill park’s parking lot, 22,908 solar panels just became California’s largest carport array and now power two parks at once
The ride queues were still running when the electricians made the final connection.
Overhead, 36 long-span steel canopies stretched the full length of the parking lot, carrying nearly 23,000 solar modules across a footprint most utility developers would be glad to have in a wheat field.
The site is a theme park in Los Angeles County, roller coasters on one side, 14 acres of bifacial glass on the other.
So the parking lot gives with one hand and takes with the other, and the net result depends on how well the canopy structures manage airflow beneath the array.
And on October 2, 2026, California’s largest solar carport sent its first electrons to the grid.
The question the installation immediately raises is not whether it works, but what a parking lot does to a 12 MW system that flat desert ground simply cannot.
Why a parking lot is a genuinely different engineering surface than open ground
A conventional ground-mounted solar field sits on grade, which means rain washes dust off at an angle, mowing crews can reach every row and the only thing below the panels is soil. A carport array is mounted eight to twelve feet in the air above asphalt, and that single fact changes almost everything about how heat, soiling and maintenance behave. Asphalt absorbs heat aggressively through the day and releases it after sunset, which means the air column directly beneath a carport panel stays warmer longer than the air beneath a field-mounted row at the same latitude.
Warmer air means higher module temperatures, and higher module temperatures cost yield. Silicon panels lose roughly 0.3 to 0.5 percent of their rated output for every degree Celsius above their test temperature, so a parking lot that runs ten degrees hotter than open ground can quietly shave four or five percent off a system’s production before a single cloud appears. The designers here used bifacial modules rated at 540 watts each, which capture reflected light from the pale asphalt below, and that rear-side gain is one direct way the site’s surface fights back against its own heat penalty.
So the parking lot gives with one hand and takes with the other, and the net result depends on how well the canopy structures manage airflow beneath the array.
What is actually standing over 4,315 parking spaces in Los Angeles County
The completed system is rated at 12.37 MW and spans approximately 637,000 square feet of solar canopy carried on 36 long-span carport structures, using 22,908 bifacial solar modules. That footprint works out to roughly 14.6 acres, which is a meaningful piece of land for a solar array inside any city boundary, let alone one that was already occupied and generating revenue as a parking lot.
Behind the panels sit a 2 MW, 8 MWh battery energy storage system and 109 electric vehicle charging connectors spread across guest and team member spaces, covering approximately 4,315 parking spaces in total. The battery is small relative to the array’s daily production, but its role is smoothing the sharp demand spikes that a park full of electric rides and refrigeration can throw at a grid connection in the first minutes after gates open.
The system is linked to the Southern California Edison grid, so any surplus above the park’s instantaneous need flows out rather than being curtailed. Annual generation is projected at approximately 20.8 million kWh of clean electricity, enough to supply around 2,874 average California homes for a year, or, put another way, enough to recharge roughly 38 million typical electric vehicle batteries.
The record the carport just claimed, and where the evidence came from
The project is the largest solar carport installation in California and one of the largest single-site commercial solar carport projects in the United States, designed to offset 100 percent of the annual electricity consumption of both the amusement park and its adjacent water park. That double-park ambition is what drove the scale: a single theme park in southern California draws enough power to justify a utility-grade installation, and adding a second site on the same grid connection pushed the module count past 22,000.
The park president, Brian Oerding, put it plainly in the project announcement: “This is a transformative moment for Six Flags Magic Mountain and our sustainability journey. By investing in renewable energy, we’re taking meaningful action to reduce our environmental impact while helping build a more sustainable future for our guests, team members and community.”
The figures were confirmed in a verified project release published on October 2, 2026, and the announcement coincided with the start of National Energy Awareness Month, with the installation developed in partnership with Solar Optimum as well as local community and government officials. For solar developers watching commercial carport economics, the project is now the clearest California benchmark available.
The complications a theme park imposes on a solar array nobody planned for
A theme park is not a warehouse roof or a flat commercial lot and the differences compound over time. Roller coasters throw vibration through the ground continuously during operating hours, and that cyclic stress travels into the steel columns that carry 637,000 square feet of racking. Standard commercial carport structures are engineered for static loads and occasional wind events, not for the sustained, repetitive shake of a ride running 400 feet overhead hundreds of times a day.
Soiling is also unusual here. A standard parking lot accumulates tire rubber, brake dust and road grime on any horizontal surface. Bifacial modules with a rear glass face pointing down at asphalt collect that soiling on their underside too, and rear-face soiling is harder to clean than a top face because the modules are mounted tight to the carport rail and automated wash systems cannot reach beneath them. Just as panel orientation changes how much energy reaches the grid at peak hours, panel position above a reflective surface changes how much soiling matters.
And then there is the crowd itself. Guest vehicles, food trucks and maintenance equipment park under the canopy every single day, which makes the kind of ground-level access that a field crew takes for granted nearly impossible on a busy weekend. The 109 EV chargers wired into the same structure mean electrical maintenance work must be coordinated around a live charging network that guests depend on.
What the thrill park model opens up for commercial solar across the country
The more consequential implication of the Magic Mountain project is how many similar surfaces exist across the United States. Theme parks, stadium lots, airport aprons, big-box retail and casino complexes all share the same profile: vast sealed surfaces under full southern exposure, existing grid connections, and a building or attraction next door that runs a very large electrical load. Most of those surfaces are currently doing nothing for the energy system except absorbing heat and sending runoff into storm drains.
The carport model also sidesteps the land-use tension that follows utility-scale solar into agricultural or desert settings. Floating arrays on mine reservoirs solve a similar problem, finding a surface that is already committed to something else and adding generation on top of it, and the engineering tradeoffs of that choice are real in both cases.
Even so, the heat penalty, the soiling complexity and the structural vibration risk are genuine limits. Twenty-two thousand modules above asphalt in Los Angeles County will face summer temperatures that challenge any silicon cell’s rated output, and the first few years of metered production data will tell investors whether the bifacial rear-gain is fully compensating for the thermal drag. If it is, the thrill park carport stops being a curiosity and becomes a template. If it falls short, the gap will clarify exactly how much rear-side gain commercial developers can count on when the surface below them is dark asphalt rather than pale desert soil.
The roller coasters will keep running either way, and the answer should arrive in the next annual generation report.
