For anyone reading this who thinks "you can't buy plugin solar panels from Lidl!" here's a link to Lidl Germany where that is definitely a thing:

Also, I need to tag @balkonsolar here. He's been promoting this in Germany for some time, and wrote to Ed Milliband last year to try and get some movement on it in the UK.
