It spans the whole Earth, from Arizona to the South Pole. I wonder what the Canadians have to say about that comment?
Religious? When did Greenpeace become religious?
From past experience, simulators are great for replicating known scenarios (including a limited set of failure scenarios).
But real, physical things will fail in strange ways that are hard to predict or can be hard to simulate.
Eg, perhaps some of them have a slight tendency to lean to the left (uneven legs during manufacturing), some of them might be intermittently blind on the right side but only when turning right (maybe manufacturing machine leaves a dry joint when soldering the right sensor, not found during stationary testing), parts start to fail intermittently as they age, the vibration of 10 neighbours is enough to cause trouble to one robot equi-distance from them all, etc.
Making it much easier to read the 3 characters that fit on the 5" screen...

It's the **Leaf** that he said was in Cat D (worse, more expensive).
The utility allows the water in the high dam to fall down into the low dam, generating electricity using turbines.
Ideally your solar could be used to pump some of that water from the low dam back to the high dam.
At night time, the water can flow down again.
The two dams become a huge battery.
I believe many utilities already do this in reverse.
Average day time power is provided by gas/oil/coal/etc to cover slightly less than peak.
At night time, when user demand is lower, the excess power is used to pump the water up to the high dam.
Back in daytime again, the peak demand is provided by allowing the water to go down again through turbines.
Thus the gas/oil/coal/etc generators can be smaller as the production of electricity is spread across the entire 24 hours instead of at peak time.
