The Sun Finally Pays the Bill: Cozumel Vacation Rentals Flip the Switch to Solar as Electricity Rates Climb

Local accommodation providers install photovoltaic systems as CFE rates increase and solar installation costs decline

There is a specific sound everyone in Cozumel knows. It’s the hum of a mini-split air conditioner kicking on in the middle of a humid July afternoon. For years, that sound meant relief. Lately, for vacation rental owners, it sounds a lot like money burning.

But a quiet shift is happening on the rooftops of San Miguel.

Faced with climbing electricity rates from the CFE (Comisión Federal de Electricidad) and a dramatic drop in the cost of technology, local property owners are taking matters into their own hands. They are turning to the one resource Cozumel has in infinite supply: the sun.

Leading this charge are places like Stingray Villa, a boutique vacation rental that recently completed a full solar photovoltaic installation. They aren’t alone. Across the island, what was once considered a luxury “green” add-on has become a matter of basic economic survival.

The “DAC” Trap: Why the Bills Hurt So Much

To understand why this is happening now, you have to understand how electricity billing works in Mexico. It’s a bit different than what we might be used to back in the U.S. or Canada.

The government subsidizes electricity heavily—up to a point. For a regular house with a few fans and a fridge, the bill is incredibly low. We’re talking pennies.

But there is a cliff.

It’s called the Tarifa de Alto Consumo (DAC), or High Consumption Tariff. If a property burns through more than 2,000 kilowatt-hours (kWh) in a two-month billing cycle, CFE essentially says, “Okay, you’re on your own.” The subsidies vanish. The rate skyrockets.

“It’s not a gradual increase; it’s a wall,” says one local property manager.

For a vacation rental, staying under that limit is nearly impossible. You have guests coming in from snowy climates who aren’t used to the tropical heat. They run the AC at 18°C (64°F) all day and night.

The result? Bills that can easily hit 25,000 pesos (about $1,350 USD) every two months. That hurts. For a small business owner, that’s not just an expense; that’s the entire profit margin for the month.

The Math Finally Makes Sense

For a long time, the solution was just to grit your teeth and pay it. Solar was a nice idea, but it was priced for the wealthy. Ten years ago, rigging a house for solar could set you back $10,000 or more. The logistics of getting panels to an island added to the headache.

That has changed. Drastically.

Just like flat-screen TVs and smartphones, the tech got better and the price crashed. Today, a residential-scale system in Cozumel costs between $3,000 and $5,000.

Do the math. If a system costs $4,000 and cuts a $1,300 bi-monthly bill down to peanuts, the payback period is shockingly short, often just two to three years. After that the energy is essentially free.

“It’s a no-brainer now,” says a representative from a local solar installation firm, noting that inquiries have doubled in the last year. “It used to be about being ‘green.’ Now, it’s just smart business. If you aren’t looking at solar, you’re throwing money away.”

How Stingray Villa Made the Switch

Stingray Villa, a favorite spot for divers and families, recently flipped the switch on their new system. For them, the move was about stabilizing the business.

Running a mini-resort means you have high fixed costs. You can’t control the price of soap, you can’t control taxes, and you certainly can’t control the weather. But by installing solar, they’ve effectively locked in their energy costs for the next 20 years.

The system works through “net metering.” During the blazing hot afternoon hours, (when the sun is highest and the AC demand is peaking) the panels produce more power than the villa needs. That excess juice gets sent back to the CFE grid. The meter literally spins backward.

At night, the property pulls power from the grid. At the end of the billing cycle, the CFE tallies it up. If you generated as much as you used, you pay practically nothing.

No massive battery banks. No complex off-grid wiring. Just a smart connection to the existing system.

What This Means for the Guest

Here is the interesting part for travelers in their 40s and 50s. We are starting to care about this stuff.

We aren’t just looking for a king-sized bed and a pool anymore. We’re looking for places that align with our values. We know about climate change. We worry about our carbon footprint, even when we’re sipping margaritas.

When a traveler sees that a property runs on solar, it signals something. It says the owners care about the island. It says they are investing in the future.

Industry data backs this up. More travel booking engines are adding “sustainability” filters because users are asking for them. Staying at a solar-powered villa feels better than staying at a mega-resort chugging diesel to keep the lights on.

The Future is Bright (and Hot)

This trend isn’t slowing down. As CFE rates continue to creep up and the summer temperatures hold steady at “scorching,” you’re going to see panels popping up on more roofs across Cozumel.

It’s happening at private homes, dive shops, and restaurants. The island is slowly, panel by panel, building a more resilient power grid.

For the owners of Stingray Villa, the project is done, but the benefits are just starting. They’ve managed to do the impossible: they found a way to keep the AC running, keep the guests happy, and stop dreading the arrival of the mailman.

It turns out, the best way to beat the heat in Cozumel is to let the sun pay for it.
