Given how cheap they are I'd probably just give it a go, he will have different input and output voltages so his efficiency will differ from yours also.
The best option of all if you wanted to spend more would be to pick up a Sunpower 300/327W panel, those have an MPP voltage of 54V, a very basic controller would suffice.
