Check the peak separately
Reducing monthly kWh does not prove a reduction in a billed demand peak. Identify the relevant interval, timing and tariff rule.

Commercial solar in Los Cabos: start with the tariff
Compare commercial solar using the actual CFE tariff, daytime load and any demand charges. Request a project review rather than a residential estimate.

A real PDBT bill: 4,408 kWh, not a residential DAC calculation
This anonymized Cabo San Lucas bill covers 5 March–6 May 2026. It is PDBT. Its six variable components and 41.49 MXN monthly supply charge match the official Baja California Sur table published for April 2026. That is an independent rate check for this example, not proof that all months, tariff types or future bills use the same prices.
| Component / Componente | MXN/kWh |
|---|---|
| Transmission / Transmisión | 0.1801 |
| Distribution / Distribución | 0.6699 |
| CENACE | 0.0076 |
| SCnMEM | 0.0069 |
| Generation energy / Energía | 2.3540 |
| Capacity / Capacidad | 0.7050 |
| Combined variable rate / Suma variable | 3.9235 |
Rebuild the commercial invoice and account total
The combined variable rate is 3.9235 MXN/kWh. Multiply by 4,408 kWh, add two monthly supply charges, then apply IVA. The left-side market-cost breakdown explains the energy charge; adding those components again to the right-side payable energy would double-count them.
| Line | Calculation | Amount |
|---|---|---|
| Variable energy | 4,408 × 3.9235 | 17,294.788 → 17,294.79 |
| Supply | 2 × 41.49 | 82.98 |
| Subtotal | 17,294.788 + 82.98 | 17,377.768 → 17,377.77 |
| IVA 16% | 17,377.768 × 0.16 | 2,780.44288 → 2,780.44 |
| Current-period invoice | 17,377.768 × 1.16 | 20,158.21088 → 20,158.21 |
| Balance carried forward | 17,933.59 − 17,933.00 | 0.59 |
| Account total | 20,158.21 + 0.59 | 20,158.80 |
Capacity is per kWh in this PDBT example
The official PDBT table expresses its 0.7050 capacity component in MXN/kWh. Do not automatically treat that label as a separate measured-kW demand charge. Other commercial tariffs can have different demand and time-of-use rules, so a PDBT worksheet must not be reused as a universal business calculator.
An office and a restaurant can use the same kWh differently
A daytime office and an evening restaurant can have equal monthly energy but different solar overlap. Use measured operating data; the business category alone does not establish a self-consumption percentage.
Keep continuity requirements specific
A POS terminal, refrigeration and an entire kitchen have different starting and running loads. Price the backed-up circuits explicitly.
Ask for a complete commercial proposal
Request energy and demand assumptions, export terms, installed scope, downtime, maintenance and warranty service. Treat tax deductions, financing and incentives as separate matters requiring current professional confirmation; they are not guaranteed savings in this guide.

FAQ
What to clarify before quoting.
Can I use the residential calculator for my business?
A commercial tariff needs its own review. Send the actual bill and operating information so the correct energy and demand components can be identified.
Will panels eliminate demand charges?
Do not assume so. The outcome depends on the tariff’s demand measurement and whether production or storage reduces the relevant peaks.
Can a tenant install solar?
Confirm roof and electrical permissions, responsibility for repairs, contract duration and equipment ownership with the property owner before investing.
Does this example independently match official rates?
Yes: the printed PDBT components match the official April 2026 Baja California Sur table. We still show the actual bill’s period and retain precision; this does not certify other monthly schedules or every commercial tariff.
