I'd imagine so. Direct sun exposure is about 1kW per square metre. At high noon, with the receiver exactly perpendicular to the incoming sunlight.

By my VERY approximate calculations, his solar panel received about 5W from his 70W lamp. Most of it in the wrong wavelenght. So getting 360-480mW out of it (6V x 60-80mA) is actually not too bad a result.
