No bill at hand

The same sun.
Your own numbers.

With a few figures from your CFE bill, we give you a first assessment.

Where is it? Optional

Type your municipality and pick it from the list. We use it to get the real sun in your area.

What is your tariff?

It is printed on your bill, next to "Tarifa".

How much did you pay?
$MXN
How much energy did you use in that period?

It is on your bill, in kWh. For a home, this figure or your payment is enough.

Your estimate

A possible scale.
Without guessing your usage.

Enter your payment and energy, and the result appears here. If you only have one of them on a home tariff, we offer to estimate the other.

What this estimate assumes

Reference sun: 5 hours a day, until you choose your municipality. Overall performance: 80%; up to 85% of yearly usage. 550 W panels of 2.6 m². Free roof space: panels in rows, with 0.8 m between them. Assumed investment: $18,000–$24,000 MXN/kWp, without a quote.

If you choose a home tariff, savings use CFE's published steps and prices for that tariff. If not, the report assumes 65% of your payment is energy that panels could avoid. That share can change a lot depending on tariff, subsidy, taxes, fixed charges and demand. Your location improves the sun lookup; shade, structure, orientation and space are reviewed later.
