Beginning at 5 a.m., the amount of power generated increases until (11:00 / a.m. when the power generated reaches its peak (100% capacity). The solar panel continues to generate at 100% capacity until 2:00 V P.m. at which point the output begins to drop, reaching its lowest point at 7 p.m. From 7 p.m. until 8:00 . p.m., the power generated remains constant at its lowest level. 3.
