Yes, they do work.
No, I don't sell them. I am a licensed home inspector and I also do thermographic inspections for heat/AC loss and water damage.
From personal experience my Courtyard Villa was a blast furnace if you pulled down the stairs after noon on any sunny day. Now that I've installed two Solar fans? It's hot, but not Satan's breath when you open it.
What I see when I do inspections is about like this. If the ridge vent is performing properly or there are passive vents and the attic is reasonably ventilated, a Solar fan probably won't do that much. In fact, mixing venting can be a bad thing because a solar fan can scavenge from the ridge vent and recycle the hot air, not moving much.
If your ridge vent is a super small and the attic is super hot, a solar fan will help. There is also the issue with left over sheathing during builds that prevent the proper movement of air in the attic space. Some builds have a bunch of sheathing inside that needs removed to help with air flow.
Below you will see two ridge vents. One is working properly, the other is missing entirely. That second one needs a solar fan, opening or something.
