P = 5W
t = 19h x 365 = 6935h
E = P x t = 5 x 6935 = 34 675 Wh
P = 2W
t = 19h x 365 = 6935 h
E = P x t = 2 x 6935 = 13 870 Wh
P = 5W
t = 23h x 200 + 24h x 165 = 8560 h
E = P x t = 5 x 8560 = 42 800 Wh
P = 5W
t = 20h x 300 + 24h x 65 = 7560 h
E = P x t = 5 x 7560 = 37 800 Wh
34 675 + 13 870 + 42 800 + 37 800 = 129 145 Wh = 129,145 kWh
1kWh coûte 0,0979€
donc 129,145kWh coûte 129,145 x 0,0979 = 12,64€
12,64 + 12,64 x 20% = 15,17€
15,17 x 30 000 000 = 455 millions d'euros !
