I tried to attach the EDN article as a .pdf <alas!> Here it is.
Solar-array controller needs no multiplier to maximize power - 12/5/2008 - EDN

It is available on the EDN (Engr Design News) site; my design used the LT1316 from Linear Tech, but that part is user choice. That's the neat thing about the circuit, it's a P&O (perturb and observe) that only controls the normal feedback pin on a switch mode controller. You pick the controller and switch electronics from milliamps and low V up to mega-amps and big volts. This circuit does the equivalent of the kids' game - you're getting warmer, you're getting colder... and centers around the max power point!
The designer is a regular circuit contributor and bright fellow.

Gals to be here, good site.
