It is very thin and very clear and passes more light than the usual glass, Plexiglas , Kalwall and Sunlite , etc. Air Flow Moving air by the thermosyphon method requires a vertical layout. If you want a really large collector, like 4 foot x 8 foot , then it can get rather awkward. If I were to go to a really large unit I would use a horizontal collector with positive air flow provided by a solar-powered fan. These are available in several sizes and are not expensive.
Solar vents are perfect because they produce airflow in direct proportion to sunlight.
I have built a small unit of that type because, stored vertically, it only takes up 1 sq. The best tape for solar use is aluminum duct tape like Reflectex . By the way, this tape makes quick, easy, durable reflectors. Just apply rows to the backing until it is covered. Shelving I'll leave that up to you, to suit your needs, if you use the usual aluminum screen, then you don't need a frame for most sizes.
