I bought a small one for some mercury cells for older photographic equipment. Those batteries are no longer sold. The charger I bought works great. I just put it on a window sill for a day.
The larger units might work well for power tool charging. You'll have to match the output of the solar panel to the output of the 'wall wart'. Then you can eliminate the 'wall wart' from the circuit.
I think something for a roof top application is on a different scale from Sundance solar. Plus there are code issues, tying it into the buildings existing circuits, maybe business park CC&R issues, etc. I'd find a contractor who does solar panels so there's no 'gotchas' down the road.
