Just an update here.
I found that if you have a very large and greasy load you can fit 2 of the smaller tablets into the dispenser and the additional detergent gives a satisfactory wash.
For most of my washes are only small to medium size, a single small tablet still works.
For additional information of those on solar power only ( no battery yet until I have these installed in April) I wash in the middle of the day during peak generation and this has zero electricity cost.
