Bet they would work good on the moon and mars.
The problem on the Moon is the long period of darkness. That's why NASA is now talking about landing at the Lunar poles. The Moon has a flatter orbit than Earth's, and a simple tower will elevate your solar collector into the sunshine -- 24 hour sunshine.
On Mars, one again has an approximately twenty-four hour day, generally clearer atmosphere, but weaker sunlight. The mirrors would have to be larger, in order to concentrate more.
