Our Puerto Morelos home is barely occupied — bills still feel high. How do we interpret usage and find someone to verify solar and wiring?

Question

Accepted Answer

Residual bills while away usually mean hidden loads — not only the refrigerator. Daily totals in roughly the mid‑teens kWh strongly suggest pumps, inverter/idle draw, thermal loads, cooling equipment, mis-labeled metering, or the whole‑home monitor measuring more than “fridge-only.” Bring a licensed solar + electrical technician to correlate your monitoring app against CFE delivery, clamps/CT wiring, inverter settings, breakers left on, and pool/well equipment.

Local context: Expat-heavy groups in Puerto Morelos often compare peso bills without the same tariff context; solar adds a second metering story (consumption vs production vs net billing). Neighborhoods such as Selva include mixed vintages — old fridges alone can creep usage, but they rarely explain teens of kWh per day sustained without other circuits.

What to do: Gather last 12 CFE bills, inverter manual + monitoring login, breaker photos, note anything still powered (modem, DVR, septic/air pumps, heaters on “vacation”). Ask the technician explicitly: CT placement, phantom inverter draw, and whether billed energy matches billed category (net metering rules vary — verify with current policy). Compare app “day” totals to billed kWh spans — they should reconcile directionally.

Common mistake: Assuming the refrigerator is the sole load because it is the “only intentional” appliance — many silent draws stay hot year-round.
