A great way to make your home or business cooler in summer is to use solar roof ventilation like the SolarKing solar fan. Roof temperatures in Australia during summer often reach 50 to 70°C and the best way to reduce these high temperatures is to install the SolarKing roof fan\u003c\/p\u003e\n\u003cp\u003eMany homes already wind driven “whirly birds” installed on roofs. Whirly birds rely on highs winds to produce any benefits and even then they only move around 100CBM per hour for each unit. Compare this to the SolarKing that moves 2100CBM per hour, there is no comparison.  \u003c\/p\u003e\n\u003cp\u003eThe SolarKing solar exhaust fan uses the sun and only starts working when your roof space reaches 25°C so as not to remove warm air in the winter when it is needed to keep your house warm (whirly birds operate regardless of the temperature. When the sun disappears in the evening the SolarKing will stop ventilating but at this time the roof is now cooling naturally with the reduce temperature as the fan has been extracting during the day.\u003c\/p\u003e\n\u003cp\u003eHave you ever noticed how the lower level of a 2 storey home is always cooler than the upper level? This is due to the upper storey blocking extreme heat from the lower level. The SolarKing solar roof ventilation fan does the same thing, the fan replaces the hot air inside your roof with the cooler outside air. This greatly lowers the extreme heat in your roof pushing into to your living space.\u003c\/p\u003e\n\u003cp\u003eSo if are looking to make a big change to your comfort levels this summer and looking to reduce the high costs of power using air conditioners, let the free power of the sun to do the work for you and use you air conditioning a great deal less.\u003c\/p\u003e\n\u003cp\u003eThis latest V4 Model carries all the updates from the V3 model that now has a DC power connection so you can connect the included 15V\/240V Power pack so the fan can now operate after the sun goes down. The unit will switch to the optional power pack automatically and then when the solar level increases again the unit will switch back to solar operation. The unit will still turn off automatically when the temperature drops below 25 degrees. The V4 also carries the updates made to the V3, the motor now keeps a stable speed when operating on solar rather than instantly speeding up and slowing down as clouds go past. The motor still runs at max speed in full sun but won’t suddenly slow down and speed up when clouds pass. The V4 just like the V3 now has the lowest noise output and has very quiet operation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch5\u003eHOW MANY DO I NEED FOR MY HOME?\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch3\u003eEstimate Roof Space Volume\u003c\/h3\u003e\n\u003cp style=\"white-space: pre-wrap;\" class=\"break-words\"\u003eThe number of fans required depends on the volume of air in the roof space that needs to be ventilated.

continue to get hotter and so do our homes. A great way to make your home or business cooler in summer is to use solar roof ventilation like the SolarKing solar fan. Roof temperatures in Australia during summer often reach 50 to 70°C and the best way to reduce these high temperatures is to install the SolarKing roof fan\u003c\/p\u003e\n\u003cp\u003eMany homes already wind driven “whirly birds” installed on roofs. Whirly birds rely on highs winds to produce any benefits and even then they only move around 100CBM per hour for each unit. Compare this to the SolarKing that moves 2100CBM per hour, there is no comparison.  \u003c\/p\u003e\n\u003cp\u003eThe SolarKing solar exhaust fan uses the sun and only starts working when your roof space reaches 25°C so as not to remove warm air in the winter when it is needed to keep your house warm (whirly birds operate regardless of the temperature. When the sun disappears in the evening the SolarKing will stop ventilating but at this time the roof is now cooling naturally with the reduce temperature as the fan has been extracting during the day.\u003c\/p\u003e\n\u003cp\u003eHave you ever noticed how the lower level of a 2 storey home is always cooler than the upper level? This is due to the upper storey blocking extreme heat from the lower level. The SolarKing solar roof ventilation fan does the same thing, the fan replaces the hot air inside your roof with the cooler outside air. This greatly lowers the extreme heat in your roof pushing into to your living space.\u003c\/p\u003e\n\u003cp\u003eSo if are looking to make a big change to your comfort levels this summer and looking to reduce the high costs of power using air conditioners, let the free power of the sun to do the work for you and use you air conditioning a great deal less.\u003c\/p\u003e\n\u003cp\u003eThis latest V4 Model carries all the updates from the V3 model that now has a DC power connection so you can connect the included 15V\/240V Power pack so the fan can now operate after the sun goes down. The unit will switch to the optional power pack automatically and then when the solar level increases again the unit will switch back to solar operation. The unit will still turn off automatically when the temperature drops below 25 degrees. The V4 also carries the updates made to the V3, the motor now keeps a stable speed when operating on solar rather than instantly speeding up and slowing down as clouds go past. The motor still runs at max speed in full sun but won’t suddenly slow down and speed up when clouds pass. The V4 just like the V3 now has the lowest noise output and has very quiet operation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch5\u003eHOW MANY DO I NEED FOR MY HOME?\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch3\u003eEstimate Roof Space Volume\u003c\/h3\u003e\n\u003cp style=\"white-space: pre-wrap;\" class=\"break-words\"\u003eThe number of fans required depends on the volume of air in the roof space that needs to be ventilated.
