Great solar control

Built our own greenhouse long and narrow between the house and the fence. Tried to cool it passively, but in the summer temps of 110-116 F, not enough. We use a big evap cooler and could get by with just a couple of louver vents without solar control for exhaust. We use the solar control for those transition times twice a year, where power cooling is not necessary, but ventilation is mandatory to avoid high temps that would stunt our plants. The solar opener barrel is high quality with brass fittings and with the four we have been using for about ten years, none of them have leaked or failed. The adjustment knob is hard to turn and I have to pull down on the operating arm at the bottom to adjust it, but I count that as a plus because the adjustment does not creep and change over time. This is a high quality passive control and most necessary for our greenhouses.

Greenhouse heats up.The solar opener activates.How ever,if its cold outside and your exhaust fan is on.The solar opener will close when cold outside air hits the solar opener.And your fan is still on.
