Why this score
How it's calculated
This is a first estimate using the data on this bill. It is not a quote or a promise of savings. How we calculate
01 Your usage
This count shows which data was found; it doesn't guarantee the reading is exact. Confirm the amounts and usage on your bill.
- What you used on this bill

- Monthly average

- Yearly usage

A kWh is the energy a 1,000-watt appliance uses when it runs for an hour. It is the unit CFE charges you in.
Service characteristics
Technical data CFE uses to calculate some charges. It is not energy usage.

Average of the last 12 months. If you go over it, CFE can move you to DAC; to get back to your tariff, that average has to fall below the limit again.

Which part of your bill do panels lower?
Not all of your bill depends on the kWh you use. Here is what would happen to each part.
- What you save for each kWh you stop buying
- —
Rule of thumb for a system at $18,000 to $24,000 per kWp and 5 hours of sun a day. Your score also uses your tariff and usage.

04 Your panels
A first idea, without a quoteUsage and period length are needed to calculate a system.
You would need about — panels.
- Free roof space they would take
- —
- Energy they would produce
- —
- What they would cost to install
- — Reference price, not a quote.
- What you would save per month
- — One-year average, on energy and its IVA where it applies. A given bill may save more or less, depending on what you use in that period. The fixed charge, street lighting and past-due amounts stay.
- How long until they pay off
- — After that, the savings are yours. Panels usually last about 25 years.
How long until they pay off?
- Without panels: just your bills
- With panels: their cost plus your bills
- Depending on final cost
- When they finish paying off
| Year | Without panels | With panels | Difference |
|---|
What if you leave DAC?
Your bill doesn't say which tariff you would have after leaving DAC. You can find it on an earlier bill; it also depends on your town's climate.

Before deciding, check your roof
- No shadeTrees, buildings or water tanks (tinacos) that shade the panels lower their output.
- One continuous spaceA continuous area is better than many pieces separated by water tanks, antennas or skylights.
- Strong enough for the weightAn installer should confirm that your roof and its waterproofing can support the structure.

Each reference panel is 550 W and measures about 2.6 m². The goal is to cover 85% of your yearly usage, at 80% performance. It does not account for shade, orientation or schedules.
Refine the estimate with your location
The more sun your area gets, the fewer panels you need. Move the pin to your roof and the estimate updates.
