solar roof fan

If the solar fan has been activated, you should be able to feel that the solar fan button feels slightly depressed (ie, no longer flush). It doesn't depress very much, but you should be able to feel the difference bewteen the on, and off positions. I think Toyota could have done a better job with the ergonomics of this button.

The system takes about 10 minutes (or so) before it activates after the car is locked. Assuming you have sunny conditions, the fan in the cabin of the car will come on for short periods of time if, and only if, the cabin temperature equals/exceeds the exterior/outside temperature. The fan speed is quite low, so often hard to tell when it's working unless you put your hands up to the air vents to feel it working. But it does definitley keep the cabin cooler in the Summer (when you need it most). I don't use it at all in the Fall or Winter months.

 

Thanks for explaining regarding solar fan button. I had planned to read and understand operation of the solar panel this weekend, although that option will not be needed until spring (32-40 degrees currently in South). Happy New Year to All.

 

Does anyone know how well it works in the shade. I generally get a parking space at work below some palm trees that provide shade most of the time. But I think solar works somewhat in daylight?

 

I'm not a solar power expert, but I think the solar panels need a certain amout of light (intensity) inorder to generate the voltage needed to operate the cooling fan. That said, they work best in direct sun light...not sure if they will work in the shade, or on cloudy day. I doubt that they will. But then again, if you're in the shade, the interior of the car should NOT be heating up due to solar radiation (which is really what the system is designed to reduce).

Remember, the system is designed only to help equilibrate the cabin temperature with the outside temperature. If the temperature outside is hot, but cloudy/shaded, the inside of the car should not be appreciably hotter, and therfore, no solar coolling should be needed.

 

That's actually very clever. Thanks for the post, and to whomever though of doing this...good idea.

 

The solar panel doesn't use battery power right? Some people say it doesn't and some say it does. Which is which?

 

The fan on mine keeps running after I get in the car. Even in a bit of shade or on a dull day there is a bit of air movement - less than the lowest setting but still significant.

On a really sunny day it seems to build up to hurrican strength.

The remote aircon is good but it stops the moment the SKS system opens a door. Also it seems to put it into recirc mode each time.

Sat in the car for a lunch break and all the suddenly the air blowing into my face. The air is definitely lot more than I can ask for and it definitely help my interior today, 60 here and sunny. Let's see how it performs in 90+ in summer days!
