Solar Energy• Average = 80km per day
• Small electric commuter: 5kWh/100km = 4kWh/day
• PV electrical energy• 5kWh per day• 1kW array = 5 x 200W panels• 10m2
• PV cells cost - R100’000, once-off, for 25 years
• PV life = 500’000km
• 20c/km (no
increase!)

Questions?
Monday Tuesday Wednesday Thursday Friday Saturday Sunday
We have a Problem!“peak capacity”
We can solve this!
Managing the LoadWith a Smart Grid
Monday Tuesday Wednesday Thursday Friday Saturday Sunday
So back to our Problem
38GWh
That is enough for 6 million Electric Cars
So now we have a solution – We just need a Smart Grid!
