From Dave Prichard
You seem to exaggerate the problem of solar power overloading the electricity grid (30 October, p 4). I understand that buildings with solar panels draw power from the grid when they need it but may supply it to the grid if they generate more than they need. I can’t believe it is beyond the wit of experts in the industry to devise a control system which ensures that the grid only receives power from solar panels when it needs it.
