This looks at the case of with solar panels and some batteries how close can
we power a site (house) to 100%.
An interesting point is that it can be done but getting the last 3% requires overbuilding of the area of solar panels. This is were the batteries come
in.
"This is a turning point in the clean energy transition. Around-the-clock
solar is no longer just a technical possibility and distant dream, but an economic reality. It unlocks game changing opportunities for energy-hungry industries like data-centres and manufacturing. Solar will be unleashed.
The change is new – the costs and quality of grid batteries have improved
so much in the last 12 months. Now it’s time for policy and investment to catch up."
It looks as the ground is shifting and the problems of cost have crossed the line and now we need to consider the problems which remain. Connection to
the grid and environmental damage.
