Tha fan sucks air from sensor ,and put out from the roof the hot air look the radiation shield design .

I make a better picture electronic design.

Νο complicated it is a very easy design no regulator for low voltage 6 volt at night only serial resistor .If you use 10 watts solar panel it will be better for fast charge battery . If you use the foul speed at night fan ,it is not good idea because you have wrong temp data. Davis weather station fan at night it turn to half speed. Serial resistor at fan the night i beleive it is better because cut the voltage at 6 volt ,and battery life is to long ,no circuits with manny electronick components ,just simple two resistors and one relay B)

Hi all I make a electronick design (and i thing to build it )for to work a pc fan in a radiation shield The day it will turn foul turn with 12 volt dc ,at the night at half turn with 6 volt dc For low drop the volt from 12 volt to 6 volt i use one resistor 80 ohm at 1 watt from the type : 12-6/0.075 =80 και 6*0.075 = 0,45w Sollar panell --> charge controller-->battery-->80 ohm resistor to relay for 6 volt dc at fan the night. Solal panel--> 12 volt at fan the day , Solar panel -->i use 162 ohm resistor for drive to relay to cut the contacts to relay at 10 volt dc and down because before without resistor the relay closed the contacts at 7 volt dc (i make experiments with a power suply 0-30 volt). Fan--> to relay When it is day with sun solar panel give 12 -16 volt and the relay closed to batery circuit and solar panel it give power to fan ,the night the when drop the power from solar panel ,open to circuit to relay and give power to fan from the battery . Tha material it is A sollar panel 12-16 volt 5 watts or 10 watts for better results http://www.maplin.co.uk/Module.aspx?ModuleNo=96861#features A charge controler 12 volt 5 amber http://www.maplin.co.uk/Module.aspx?ModuleNo=37774 one batery lead acid 12 volt 2,2 Ah http://www.batteries.gr/product.asp?catid=2659 a pc fan for radiation shield 12 volt 8 x 8 cm http://elektronik.gr/eshop/index.php?main_...42f4cf3d69766d9 one relay 12 volt 2 contacts http://elektronik.gr/eshop/index.php?main_...oducts_id=16973 a water proof case for to put inside batery,charge controler,pcb with relay and 2 resistors http://www.emimikos.gr/shop/product.php?pr...=505&page=1 I have and one design ,but i am sorry, i am not good to design ,i hope to understand the design.
