Apple Tree Analogy - Solar Panel

We were chatting about system sizing for solar hot water and photovoltaic, that if you size it to meet peak demand in worse case scenario, you will have surplus.  Then seeing a fruiting apple tree, I made an analogy, there are only so much apple you can eat, even if you can put some in freezer, you will still have surplus that either yield very little or even cost money to export.  Should always be happy to feed the hungry neighbours.
