This guide uses a baseline daily energy assumption of 5,000 Wh/day for a typical example tiny house configuration. This is a sizing estimate, not a site-specific electrical design.
Using an estimated daily demand of 5,000 Wh, 4.5 peak sun hours, and a 78% system efficiency assumption, the estimated solar array need is approximately 1,425 W.
With 5,000 Wh of daily use and an assumed 85% usable battery fraction per cycle, the estimated storage need is approximately 5,883 Wh. This accounts for not fully depleting the battery bank on a typical day.
Based on an estimated peak AC load of 2,400 W and a 1.30× surge margin, the estimated inverter need is approximately 3,120 W. This provides headroom for brief startup loads above continuous draw.
Limited roof real estate requiring high-voltage residential panel strings
Limited roof area may require higher-efficiency panels or alternative mounting strategies. Planning should balance available roof space against the calculated daily energy target.
SunPowerLogic compares published product specifications against the baseline sizing estimates shown above. Listed products may meet, fall below, or lack the data needed for a given requirement.

Partially Matches This Baseline
Battery capacity: Battery capacity is below the estimated requirement by 1,787 Wh (4,096 Wh listed vs 5,883 Wh needed)
Continuous AC output: Continuous AC output meets the estimated requirement (4,000 W vs 3,120 W needed)
