Off-grid sizing must balance energy across days, not just match one evening load. Tropical sites may have strong annual solar resource but still experience cloudy periods, high cooling demand and seasonal business loads.<\/p>\n\n\n\n

A useful design begins with load tiers and an agreed operating strategy for low-solar days. Oversizing every component is expensive; ignoring weather and load priority creates service complaints.<\/p>\n\n\n\n
