Solar PVC dedicated for swamp cooler only?

Question

When the sun shines the house gets hot. When the clouds obscure the sun, the house receives less heat (of course this ignores real life situations, which might involve things like humidity, heat sinks...Many nights in humid climates are hot!)

Does it not make sense then to have a solar photo-voltaic cell directly wired to a direct current fan--- for a swamp cooler? The whole set up would be localized near the roof apex, and there one could forgo the batteries and (extra) wiring to inverters and the like.ARE THERE ANY PROBLEMS WITH THIS IDEA?

Are there any efficiency problems, or safety concerns? TY
