The point almost nobody explains

A solar system without batteries goes down with the grid

It's the conversation to have before talking price, because it completely changes what you are actually buying.

During an outage, panels won't save you

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.

Panels cut the kWh. Batteries cut the kW

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

Large projects — and your home too.

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.

Hotels and resorts

Where an outage isn't an inconvenience — it's a lost night and a bad review.

Retail and shopping centers

Plenty of roof area and demand concentrated in peak hours.

Industry and manufacturing

Process continuity and control of the capacity charge.

Corporate and office buildings

HVAC-dominated load and a highly predictable consumption profile.

Cold storage and agribusiness

Cold rooms and processes where losing temperature means losing inventory.

Residential

Homes with full, silent backup: no generator, no noise, no candles.

kW

The criterion isn't your line of business — it's scale

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

What we do

From analyzing your utility bill to year-ten maintenance. One party responsible across the whole chain.

01

Engineering and permitting

Analysis of twelve months of billing, shading study, electrical and structural calculations, and complete management of the interconnection agreement with CFE.

02

Photovoltaic generation

Modules, inverters, mounting structure for metal roof, slab, ground or carport, protective devices and grounding. Engineered for each location's wind load.

03

Energy storage

LiFePO4 battery banks, hybrid inverter, automatic transfer and an energy management system with peak-shaving logic. Battery room built to NFPA 855.

04

Battery room climate control

Lithium loses service life above its thermal window. Sixty years of air conditioning hospitals and hotels apply directly here — and that's something no solar installer brings.

05

Testing and commissioning

Per-string I-V curves, thermal imaging, anti-islanding test, battery bank cycling and backup testing under real load. Closeout dossier with as-built drawings and protocols.

06

Operation and maintenance

Module cleaning, inverter maintenance, annual battery bank capacity checks and remote monitoring with a monthly performance report.

Equipment

What we build it with

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.

Photovoltaic modules

N-type monocrystalline with TOPCon cells — the technology that dominates today's utility-scale market.

  • 580 to 645 Wp per module
  • Bifacial, glass-glass
  • 12–15-year product warranty
  • 25–30-year production warranty
  • Thermal coefficient ≤ −0.30 %/°C

Inverters

Three-phase string inverters for grid interconnection, and bidirectional hybrids when the system includes backup.

  • 1,500 V DC
  • Efficiency ≥ 98 %
  • Certified anti-islanding protection
  • Built-in per-string monitoring
  • IP65 outdoor-rated enclosure

Lithium batteries

LiFePO4 banks — the most stable, longest-lived chemistry — in indoor racks or outdoor cabinets.

  • Lithium iron phosphate (LiFePO4)
  • ≥ 6,000 cycles at 90 % depth of discharge
  • BMS with cell-level monitoring
  • UL 9540A fire-safety tested
  • Scalable in rack modules

The rest of the system

The parts that never make the photo — and decide whether the system lasts twenty-five years.

Mounting structure

Aluminum and galvanized or stainless steel, engineered for the site's wind load. For metal roofing, ballasted slab, ground mount or carport.

Wiring

Double-insulated, UV-resistant 1,500 V DC solar cable; THHW-LS AC conductors; genuine MC4 connectors.

Protection devices

DC combiner boxes, thermal-magnetic breakers, gPV fuses, type 1+2 surge protectors and visible-blade disconnects.

Raceways

Cable tray, heavy-wall conduit and weatherproof fittings. Routes labeled per NOM-001-SEDE, Mexico's electrical code.

Grounding

Ground grid with rods, bare conductor and certified connectors; equipotential bonding of structure and equipment.

Monitoring and metering

Datalogger with remote access, bidirectional meters, current transformers and a communications gateway.

Transfer and control

Automatic transfer switch (ATS) and an energy management system (EMS) with peak-shaving logic.

Medium voltage

Transformers, sectionalizing switchgear and medium-voltage metering equipment for commercial and industrial interconnection.

Battery room safety

Smoke and gas detection, fire suppression, emergency ventilation and the room's dedicated climate control.

Why you won't see a list of brands here. The leading manufacturers swap positions every year and prices change every week. Committing to a logo today would mean selling you inventory, not engineering. We specify the technical minimum the equipment must meet, and when we quote we present two or three current options with their actual warranties in Mexico — you decide on data, not brand loyalty.

Our advantage

We're the only ones who can redesign both the load and the generation

A solar installer sizes the battery for the peak they find. We can lower that peak first.

Air conditioning creates the peak

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.

Lower the peak before buying the battery

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

All across Mexico. And wherever we're hired.

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.

All of Mexico has good solar resource

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.

Acapulco

Guerrero

Lowest seasonality
1,791kWh per kWp per year
5.98peak sun hours
19°optimal tilt

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.

Puerto Vallarta

Jalisco

1,699kWh per kWp per year
5.56peak sun hours
23°optimal tilt

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.

Monterrey

Nuevo León

1,637kWh per kWp per year
5.29peak sun hours
24°optimal tilt

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.

Ciudad de México

CDMX

1,814kWh per kWp per year
5.84peak sun hours
22°optimal tilt

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.

Cancún

Quintana Roo

1,662kWh per kWp per year
5.44peak sun hours
20°optimal tilt

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.

Chetumal

Quintana Roo

1,682kWh per kWp per year
5.59peak sun hours
19°optimal tilt

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

How we work

Six stages, one party responsible, and the CFE paperwork handled by us from start to finish.

  1. 01

    Site survey

    We visit the site, analyze twelve months of utility bills and measure power quality for a week.

  2. 02

    Engineering

    We size generation and storage, and deliver the single-line diagram, calculation report and layout drawings.

  3. 03

    CFE paperwork

    We manage the interconnection agreement under Distributed Generation (Generación Distribuida). Complete filing: fifteen to twenty business days.

  4. 04

    Installation

    Structure, modules, inverters, battery bank and switchboards. Our own crews, not subcontractors.

  5. 05

    Verification

    Sign-off by a certified electrical verification unit (UVIE), acceptance testing and commissioning with the client present.

  6. 06

    Operation

    Remote monitoring, monthly performance reporting and scheduled preventive maintenance.

Calculator

How much solar fits your property — and what it does for you

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.

kWh per month

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.

Energy only. Doesn't include demand-shaving savings, which on large-demand (GDMTH/GDMTO) tariffs are often half the bill.
Heads up: this exceeds Distributed Generation At this capacity the project falls outside the Distributed Generation regime and requires a self-supply permit from the National Energy Commission (CNE). That changes the paperwork, the timeline and the compensation scheme. We handle it, but it has to be planned from day one.

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.
