• Six Flags Magic Mountain has fully energized a 12.37 MW solar carport — the largest in California and one of the largest single-site commercial carports in the US.
  • The installation spans 36 carport structures over 4,315 parking spaces, paired with a 2 MW/8 MWh battery and 109 EV chargers.
  • Expected to generate 20.8 million kWh per year, it will offset 100% of the annual electricity use of Magic Mountain and neighboring Hurricane Harbor.

The Six Flags solar carport at Magic Mountain is now fully live — and it’s a landmark for commercial solar in America. Developed with Solar Optimum and energized at the start of National Energy Awareness Month in October, the 12.37 MW installation is described by Six Flags as the largest solar carport in California and one of the largest single-site commercial solar carport projects in the United States.

The scale is what makes it remarkable. Thirty-six long-span carport structures cover roughly 637,000 square feet of parking — 4,315 spaces in total, split between 3,544 guest spots and 771 employee spaces — using 22,908 RECOM 540-watt bifacial modules. Electrek’s coverage notes the project broke ground on November 1, 2023, and the company’s own announcement frames it as the centerpiece of its energy strategy. Six Flags expects the array to generate about 20.8 million kWh per year — enough to offset 100% of the annual electricity consumption of both Magic Mountain and the neighboring Hurricane Harbor Los Angeles water park, equivalent to powering roughly 2,874 homes.

More than just shade: solar plus storage plus EV charging

What elevates this project beyond a big parking canopy is the bundle. Alongside the panels, Six Flags installed a 2 MW/8 MWh battery energy storage system and 109 EV charging connectors across the guest and employee lots. That combination — generation, storage, and vehicle charging in one site — is the commercial-scale formula the clean-energy industry has been evangelizing for years, now operating at a theme park that draws millions of visitors annually.

The battery does the quiet heavy lifting: it stores midday solar surplus and discharges it when the park’s evening demand peaks, shaving the demand charges that make up a large share of commercial electricity bills in California. The EV chargers, meanwhile, turn a parking asset into a mobility hub — and give every visitor a tangible encounter with the energy transition between the roller coasters.

The Six Flags solar carport and the economics of parking-lot solar

Solar carports have always had a compelling pitch: parking lots are dead space bathed in sunlight, and covering them generates power while shading cars — a genuine amenity in Southern California heat. The obstacle was solar carport cost: steel structures, foundations, and engineering make carports significantly pricier per watt than rooftop or ground-mount systems.

Projects like this one show the economics catching up. Bifacial modules — which capture reflected light from the pavement below — squeeze extra output from the same footprint. Rising commercial electricity rates and demand charges in California improve the payback. And the visibility value is real: millions of visitors will park under these panels every year, making the carport a marketing asset as much as an energy one. That combination of generation, shade, storage, and brand signal is why analysts expect largest solar carport US records to keep falling.

Grid-connected, not off-grid

The project stays connected to Southern California Edison’s grid: it imports power when onsite generation falls short and exports surplus when production exceeds the parks’ needs. That two-way relationship is typical of large commercial solar — the grid acts as the ultimate battery — but the onsite storage reduces how much the project leans on it, and gives Six Flags a measure of resilience during outages or price spikes.

Six Flags puts the environmental benefit at more than 8,000 tons of CO2 avoided per year, equivalent to taking 3,182 gasoline vehicles off the road. Corporate claims like that deserve the usual grain of salt — but the underlying math, 20.8 million kWh of clean generation displacing grid power, is straightforward. For context on how corporate-scale solar is reshaping the market, see how utility-scale projects in Texas and American-made rooftop modules are expanding the solar footprint from both ends of the market.

Why parking-lot solar matters for the energy transition

The deeper significance of the Six Flags project is about land. One of solar’s persistent criticisms is the acreage it demands — ground-mount farms compete with agriculture, habitat, and development. Parking lots sidestep that conflict entirely: they are already paved, already graded, and already connected to the grid through the buildings they serve. Dual-use solar like this turns a sunk land cost into a generating asset without a single acre of new disturbance.

California, with its combination of high electricity prices, strong sun, and aggressive climate targets, is the natural proving ground. But the model travels: big-box retail, airports, universities, and office campuses across the US sit on similar oceans of asphalt. The Magic Mountain carport — visible, visitable, and undeniably cool — may do as much for the technology’s reputation as a dozen policy white papers. People remember parking under a solar canopy; they don’t remember capacity statistics.

What’s next

Watch whether Six Flags replicates the formula at its other parks — the company operates dozens of properties across North America, and a successful flagship makes the business case easier to repeat. More broadly, expect parking-lot solar to keep climbing the commercial agenda: the technology is proven, the structures are getting cheaper, and every project like this one normalizes the sight of a solar canopy overhead.

The real milestone would be when a project like this stops being news. Until then, a theme park running its roller coasters on sunshine from its own parking lot remains a pretty good advertisement for where commercial solar is headed.
