My (large) fridge hasn’t even pulled 1kWh today. Modern fridges are impressively efficient.

I’m steadily electrifying my life - and adding solar panels as I go.

Solar is already super modular and if you package the panels, then you rob the consumer of the ability to pick a panel that works for them (physical size for example, but where you live will also have a big impact on capacity requirements). Also, solar panels have a lifespan that exceeds most consumer appliances. I just replaced a ten year old stove but my solar panels have a 25 year warranty. The replacement cadence is very different.
