Zenit Solar

Zenit Solar answers everyday questions about electricity costs and solar power in Mexico with the same calculation engine Zenit's solar installers use for their quotes. No account or sign-up is needed, and results come back in Spanish, in Mexican pesos.

What it can do

• Current CFE rates for any tariff: residential 1, 1A–1F and DAC (summer and non-summer consumption blocks, DAC limit), low-tension PDBT, GDBT, RABT and APBT, medium-tension GDMTO, GDMTH, RAMT and APMT (including GDMTH base, intermediate and peak periods) and the 9-CU/9-N agricultural tariffs, as published by CFE, before VAT, with the publication month.
• Estimated CFE bill, month by month, for a given monthly consumption (kWh), including the summer/non-summer difference and a warning when consumption exceeds the DAC limit.
• Solar system sizing: how many panels and how many kW cover your consumption, using the solar yield of your region (NREL PVWatts data by CFE tariff region).
• 25-year savings projection with regional CFE rates and, when you give the system price, payback, IRR and NPV.
• Battery (BESS) sizing for peak shaving in businesses on GDMTH/GDMTO tariffs, verified with an hourly dispatch simulation.

How to use it Tell it your consumption (monthly or bimonthly kWh, as printed on your CFE bill), your tariff (also on the bill) and your state. For example: «Consumo 300 kWh al mes en tarifa 1C en Mérida, ¿cuánto pagaría de luz?»

Limitations All figures are estimates based on CFE's published tables and typical solar yields; they are not a quotation, an official bill or financial advice. The plugin cannot read your CFE account or your actual bill, covers only CFE tariffs in Mexico, and applies VAT at the general 16 % rate. CFE updates its rates monthly; the plugin refreshes them when they are published.
