Real output figures based on Ghana's sun hours, not lab-condition numbers.
A panel's rated wattage (like 400W) describes peak output under ideal lab conditions — full sun, optimal angle, cool temperature. Real daily output is lower and varies with cloud cover, panel angle, and temperature, since heat actually reduces panel efficiency slightly.
In Ghana's climate, expect a 400W panel to produce meaningful usable energy across roughly 6 peak sun hours daily on average, which is exactly the number we design every system's battery sizing around, rather than relying on the optimistic rated figure alone.
Every package below is sized using real output figures, not optimistic lab numbers.
300W · Lights, fans, charging
1kW · TV, fridge, fans
2kW · AC, water pump
