A solar kit is sized by one day of use, in watt-hours. A fridge is the heavyweight: around 1,000 watt-hours a day, because it runs around the clock. A fan for six hours is about 360. Four LED bulbs for an evening, about 200. A TV for four hours, about 320. Add your home's list up and the kit size stops being a guess.
Haiti gives roughly 4 to 5 good sun hours a day. Panels are sized to refill the day's use inside those hours, with a margin for cloudy days — about 300 watts of panels for every 1,000 watt-hours of daily use, rounded up.
Whatever the home uses after dark comes out of the battery. A working rule is a battery about 1.2 times the daily use, so a fridge home at 1,500–2,000 watt-hours a day wants roughly 2.5 kWh of battery. Undersize this and the fridge warms up at 3 a.m. — the most common complaint about cheap kits.
Kit 1 (lights and phones, up to ~400 Wh a day), Kit 2 (lights, fan, TV — up to ~1,000), Kit 3 (the fridge kit — up to ~2,100), Kit 4 (whole house, above that). Two minutes with our free sizing checker gives your family's number and names the kit — before anyone sells you anything.
A fridge alone uses about 1,000 watt-hours a day. With lights and phones on top, most fridge homes land on Kit 3: roughly 450–600 watts of panels and around 2.5 kWh of battery once lights and phones are counted. Run the checker with your family's real list — the fridge is never the only thing on it.
Honestly, no. Air conditioning draws 1,500 watts or more while it runs; it belongs to the biggest systems, not to family kits. Any seller who says a small kit runs AC is selling, not sizing.
Usually the battery: too small for the night, drained flat daily, dead within a year or two. Sizing the battery honestly is most of what 'quality' means in a kit.
