Sizing solar panels for a DAC bill in Los Cabos

Turn annual CFE kWh into a first solar-size estimate. Check the yield assumption, roof limits and export treatment before comparing panel counts.

In this guide

Calculate a starting size, then test it

Illustrative inputs: 12,000 kWh/year of demand and an assumed net yield of 1,600 kWh per installed kW per year. Dividing gives 7.5 kW. These are teaching assumptions, not a production forecast for your roof.

Annual demand12,000 kWh

Starting capacity12,000 ÷ 1,600 = 7.5 kW
At 500 W per panel7,500 ÷ 500 = 15 panels

Why 15 panels is not the finished design

Annual production does not show when you will use the electricity. The proposal still needs roof shading, usable area, electrical limits and the actual CFE contract.

Separate production from savings

State directly used energy, exported energy and any battery losses. Show how the contract values each flow.

Keep a roof buffer

Allow for access, drains, equipment, future repairs and structural review. Satellite area is a screening input.

Compare proposals on the same basis

Request annual production with assumptions, the remaining CFE bill, installed scope and maintenance exclusions. If one proposal has more panels, ask which additional load or contract credit makes them useful.

FAQ

What to clarify before quoting.

How many panels do I need for DAC?

The annual kWh, roof and contract determine the design. A tariff label or the pesos total alone cannot determine panel count.

Can I cover all annual usage and still pay CFE?

Yes. Timing, export treatment, fixed charges and other bill items matter. Ask for the modeled bill components rather than a zero-bill promise.

Does this example predict my installation?

No. The yield and panel size are declared assumptions. Your roof assessment and equipment data must replace them.

Sources

External sources used as context.

These references provide technical context. Your location, energy needs and project scope still need an individual assessment.

Start with the property’s actual information

Use your CFE bill for an initial assessment. Roof conditions, equipment and the final scope need confirmation before installation.
