FAQ
Should I oversize panels or batteries first?
In low-sun conditions, panel oversizing usually improves daily recovery. In high-cloud windows, additional battery autonomy reduces outage risk.
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.
12V solar setup: how many battery Ah do I need?
For this load profile, estimated LIFEPO4 bank sizing is 161.7 Ah at 12V with 1-day autonomy.
