Load Breakdown

Appliance Power Daily Runtime Wh/Day
Fridge (60W x 24h) 60 W 24.00 h 1440 Wh

Regional Sun-Window Guidance

Strong annual sun profile with stable planning assumptions.

Use local monthly irradiance data to tune peak-sun-hour assumptions before procurement.
Cloud-prone months usually benefit from higher autonomy targets and larger reserve buffers.
For winter-heavy climates, panel overbuild is often cheaper than repeated battery deep cycles.

FAQ

Is LIFEPO4 efficient for this load profile?

Yes, the model applies chemistry-specific assumptions for DoD and charging to keep estimates closer to practical planning ranges.

Can this replace a full electrical audit?

Use this for planning and shortlist decisions, then validate with measured appliance duty cycles and local irradiance history.

24V solar setup: how many battery Ah do I need?

For this load profile, estimated LIFEPO4 bank sizing is 80.9 Ah at 24V with 1-day autonomy.

How many watts of solar panels are required for 5.4 peak sun hours?

The calculator estimates 406 W panel capacity after charge and derate factors.
