It will not be too much light and will be the cause algae problems. They could be supplemented with pendant luminaries. I would invest in a light meter and determine your supplemental needs after the tank is set up under the natural light source.

the guy who uses them in az says that he had no algae problems at all.....
If the tank is set up well, there shouldn't be algae problems. The aquarium in Hawaii has many of their tanks outdoors where they get natural sunlight all day. There is also that thread on RC of the guy in Spain whose tank is in the ground of his back yard and is naturally lit with no algae problems.
I think it would probably work great for a FOWLR tank or some softies. It would be cool to have a built in light sensor that would adjust your supplemental lighting to compensate for the changing natural light. Even without something like that, I think the tank would be closer to simulating nature. We tend to run our lights at full strength 365 days a year even though the sun doesn't shine everyday.
