Hotels and resorts
Where an outage isn't an inconvenience — it's a lost night and a bad review.
Solar energy and lithium battery backup for hotels, commercial and industrial facilities — and homes. We design, install and maintain the complete system — and the HVAC around it.
APE Power doesn't start from zero. It was born inside Aire Perfecto.
The point almost nobody explains
It's the conversation to have before talking price, because it completely changes what you are actually buying.
When the grid goes down, the inverter in a conventional photovoltaic system shuts off on anti-islanding protection. That's a safety requirement, not a defect: it keeps your installation from feeding power into a line where crews from CFE (Mexico's federal utility) may be working.
The practical result: a solar system without storage stops working at exactly the moment you need it most. Backup storage is the only thing that makes a solar investment usable during an emergency.
On a large-demand (GDMTH/GDMTO) tariff, your bill doesn't just charge for the energy you consume. It also charges for capacity and distribution, and both of those charges are set by a single fifteen-minute peak in the entire month.
During winter peak hours — six to ten in the evening — panels produce nothing. Solar lowers your energy consumption and leaves the demand charges untouched. Shaving that peak takes storage, and it takes knowing when that peak happens and why.
Who we serve
We work where energy is a serious line item in operating costs and where an interruption costs real money — and in homes that simply want the lights to stay on.
Where an outage isn't an inconvenience — it's a lost night and a bad review.
Plenty of roof area and demand concentrated in peak hours.
Process continuity and control of the capacity charge.
HVAC-dominated load and a highly predictable consumption profile.
Cold rooms and processes where losing temperature means losing inventory.
Homes with full, silent backup: no generator, no noise, no candles.
If your CFE bill is on a large-demand (GDMTH/GDMTO) tariff, there's a case worth analyzing: that's where the capacity and distribution charges that storage can cut actually live. Below that threshold the return rarely justifies the project, and we'd rather tell you so before charging you for engineering. If your load is large, we don't care what business you're in. And at home? The criterion changes: a DAC tariff, a bill that hurts, or the decision to never sit in the dark again. There's a case there too.
Scope
From analyzing your utility bill to year-ten maintenance. One party responsible across the whole chain.
Analysis of twelve months of billing, shading study, electrical and structural calculations, and complete management of the interconnection agreement with CFE.

Module cleaning, inverter maintenance, annual battery bank capacity checks and remote monitoring with a monthly performance report.
Equipment
We specify by performance, not by logo: every project is quoted with tier-one equipment that meets these minimums, and the brand is chosen for availability, warranty and service coverage in Mexico at the time of purchase.
N-type monocrystalline with TOPCon cells — the technology that dominates today's utility-scale market.
Three-phase string inverters for grid interconnection, and bidirectional hybrids when the system includes backup.
LiFePO4 banks — the most stable, longest-lived chemistry — in indoor racks or outdoor cabinets.
The rest of the system
The parts that never make the photo — and decide whether the system lasts twenty-five years.
Aluminum and galvanized or stainless steel, engineered for the site's wind load. For metal roofing, ballasted slab, ground mount or carport.
Double-insulated, UV-resistant 1,500 V DC solar cable; THHW-LS AC conductors; genuine MC4 connectors.
DC combiner boxes, thermal-magnetic breakers, gPV fuses, type 1+2 surge protectors and visible-blade disconnects.
Cable tray, heavy-wall conduit and weatherproof fittings. Routes labeled per NOM-001-SEDE, Mexico's electrical code.
Ground grid with rods, bare conductor and certified connectors; equipotential bonding of structure and equipment.
Datalogger with remote access, bidirectional meters, current transformers and a communications gateway.
Automatic transfer switch (ATS) and an energy management system (EMS) with peak-shaving logic.
Transformers, sectionalizing switchgear and medium-voltage metering equipment for commercial and industrial interconnection.
Smoke and gas detection, fire suppression, emergency ventilation and the room's dedicated climate control.
Our advantage
A solar installer sizes the battery for the peak they find. We can lower that peak first.
In a hotel, a shopping center or an office building, the month's maximum demand is almost always driven by the HVAC plant. It's the largest load in the building — and the most controllable.
Sixty years of HVAC engineering let us work on that load first: sequencing, controls, efficiency. A smaller peak means a smaller battery bank — and a smaller investment for the same result.
Where we operate
Aire Perfecto has completed work in more than fifteen states and three countries. APE Power inherits that mobilization capacity: if the project warrants it, we get there.
But the sun doesn't yield the same everywhere. Across the 160 cities we have measured, production ranges from 1,421 kilowatt-hours per kilowatt-peak per year to 1,983 — a forty percent difference on the exact same system. Some states split right down the middle: Hidalgo goes from 1,886 in Pachuca to 1,483 in Huejutla. That's why we calculate with your exact city, not the state average.
Markets we know inside out
Six markets with projects or completed work, each with a different case for storage. Figures from the World Bank's Global Solar Atlas.
Guerrero
Our most even market: barely a 1.43x spread between the strongest and weakest month. A battery bank sized here performs the same all twelve months, with no oversizing for winter.
After Otis, full grid restoration took close to a month. A week after landfall, nearly half the city was still without power.
Jalisco
Production bottoms out between June and September in the rainy season — exactly the months of highest air conditioning load and highest hurricane risk.
That mismatch between minimum production and maximum demand is, on its own, the case for storage in the bay.
Nuevo León
The cooler climate means every kilowatt-hour of sun converts better. The trade-off: it's our most seasonal market — December produces half of what June does.
Here the battery case isn't hurricanes — it's the summer demand peak and keeping industrial operations running.
CDMX
The country's largest corporate market, and a surprising fact: at 2,240 meters of altitude, the temperate climate converts each kilowatt-hour of sun better than the coast does. It out-produces Acapulco.
Here the battery case is the GDMTH capacity and distribution charges: the corporate peak lands right at dusk, when panels no longer produce.
Quintana Roo
The lowest solar resource among our markets — Caribbean cloud cover takes its toll — but the country's biggest cooling load: the hotel zone runs air conditioning all year, with no low season for consumption.
In Mexico's most hurricane-exposed corridor, the case isn't the utility bill: it's keeping the hotel running when the grid isn't.
Quintana Roo
A market we know from the field: we worked on the IMSS Bienestar hospital here. Moderate but very stable resource, and a grid at the far end of the peninsula, far from generation.
Being at the end of the line means more outages: backup here isn't a resort luxury, it's basic operating continuity.
Method
Six stages, one party responsible, and the CFE paperwork handled by us from start to finish.
We visit the site, analyze twelve months of utility bills and measure power quality for a week.
We size generation and storage, and deliver the single-line diagram, calculation report and layout drawings.
We manage the interconnection agreement under Distributed Generation (Generación Distribuida). Complete filing: fifteen to twenty business days.
Structure, modules, inverters, battery bank and switchboards. Our own crews, not subcontractors.
Sign-off by a certified electrical verification unit (UVIE), acceptance testing and commissioning with the client present.
Remote monitoring, monthly performance reporting and scheduled preventive maintenance.
Calculator
Move the sliders and watch the system take shape. The solar resource figures are the real data for each city.
Pick the state and its five main cities appear. 160 cities with Global Solar Atlas data.
This tells us how even your consumption is, so we can estimate your demand if you don't have it handy.
The average of your last twelve months.
The highest kilowatt draw the property pulled in any fifteen-minute interval of the month. It appears on your CFE bill as Demanda Máxima. This is what sizes the battery: panels go after the kWh, the battery goes after the kW.
Seventy percent is the usual starting point for self-consumption.
An editable assumption. CFE adjusts tariffs every month, so it's worth entering your property's actual figure.
Preliminary system concept
This is a concept estimate, not a quote. It doesn't model shading, hourly load profile or capacity and distribution charges. Formal engineering adjusts these figures — almost always in your favor once peak shaving is added.
