Solar roof vent/fan

[Where~the~wind~blows]

I am looking into solar roof vents/ fans being a farm girl I knew about this unit and others like it, but &nbsp;it's very big, and that doesn't really bother me, but since I know nothing about watts/amps.volt ect or what I am reallt getting with each unit I turn to the experts:<br /><br />From Farm tek:<br /><a href="http://www.farmtek.com/farm/supplies/prod1;ft1_electrical_supplies-ft1_solar_power;pg109725.html">http://www.farmtek.com/farm/supplies/prod1;ft1_electrical_supplies-ft1_solar_power;pg109725.html</a><br /><br /><br />I googled looking for smaller units and found this one:<br /><br /><a href="http://www.ebay.com/itm/Solar-Power...ries_Gear&amp;vxp=mtr&amp;hash=item3a7a23b859">http://www.ebay.com/itm/Solar-Power...ries_Gear&amp;vxp=mtr&amp;hash=item3a7a23b859<br /><br />I</a>&nbsp;have been in vans with the smaller roof top vents and wasn't really happy with the pull they provided, I will always have pets in my vehicle so I want a strong unit..... can anybody explain what these unit will do for me?<br /><br />I have a 97 conversion van.<br /><br />thanks much,&nbsp;<br />Windy

LOL ZAR! I guess the&nbsp;assumption&nbsp;is you really don't want to turn it off?

I had a similar solar fan. <br /><br />&nbsp;Actually I still have it, I just do not use the fan motor or solar panel, it is now just a mushroom vent, and I have 2 counter rotating Computer muffin fans exhausting air through it. &nbsp;One fan is rated at upto 110 Cubic feet per minute, the other at half that. &nbsp;I know they do not move their combined total, but it is a factor of 40 more than the solar vent itself when I have them on high.<br /><br />My Fan was a Nicro brand, and it claimed ~1000 cubic feet per hour, &nbsp;which is nowhere near enough, but I never did suffer CO poisioning, so I guess it is enough to exhaust cooking gasses.<br /><br />Note that the Vent you link to is 696 Cubic feet per Hour.<br /><br />My Nicro vent became noisy after a few years. &nbsp;I now taped over the solar panel, and have removedthe fan blade.<br /><br />Darn I already typed this once on this forum.<br /><br />Here's a link showing my approach to ventilation:<br /><a href="/post/show_single_post?pid=1275016057&amp;postcount=12">https://vanlivingforum.com/post/show_single_post?pid=1275016057&amp;postcount=12</a><br /><br />&nbsp;

I have heard from guys who spent a lot on a stainless steel solar boat vent that it was like having nothing at all...Just a report of hearsay though...<br />As usual YMMV....<br /><br />I think I would rather go with a solar system and use a bigger 12 volt fan/vent like a Fantastic or Shur-flo.....<br /><br />Bri

<br /><br />My biggest issue is I am just not handy with stuff like that,love the concept and I know that a better unit can probably be built, if I could say I was kinda handy it would be in carpentry and plumming, electronic baffles the heck out of me and I know it's simple , I have a mental road block in my head about it.... but I still feel compelled to learn it. I do better with hands on experience as well , thank you for the link and info!&nbsp;
