Your stirling engine will not be that efficient. You need to get the temperature up, up, up to make it work. You need a decent cold-sink also.
You need space for mirror array in the garden, while solar panels can be bolted to a roof.
You will need to adjust the mirrors to track the sun to get the best benefit.
Also, you see how big the molten salt plants can get with massive fields of mirrors?
I know I can get 1kWp of PV, and an inverter, for probably less than a stirling engine and complex, curved mirror assembly will cost. It'll be more reliable as it has no moving parts --- and I can add battery banks to the system to use any excess power at night.

I love the smell of rotaries in the morning. You know one time, I got to work early, before the rush hour. I walked through the empty carpark, I didn't see one bloody Prius or Golf. And that smell, you know that gasoline smell, the whole carpark, smelled like.... ....speed.
One day they're going to ban them.
