We have a small one installed on our roof. We've also save quite a lot of money by just keeping our furnace filters and air conditioning filters changed.

You definately have that for the solar walls, but the SolarDuct is located on the roof. I think the intent is to use it for heating. But again, this would only be useful for the few hours during the year in most climates when it's cold out yet sunny.

This is something that has been known at least since Edward Sylvester Morse incorporated the idea into his solar air ventilation system circa 1888. SolarWall is a system that heats outside air before it enters a building and is very efficient from the performance standards and presentations I've seen. They've been around for a couple of decades and have a good reputation in the business. Hot air can drive ventilation and speed air flow in hot summer months just as it can heat a room during winter.

Buildings generally need cooling, not heating, when the sun is out. I’m curious about how this is used. Buildings generally need cooling, not heating, when the sun is out.
