How loud is it? Is it good for my attic guest room ?

It isnt loud at all. I have it in my greenhouse and occasionally look up to make sure it is working because I cannot hear it. As for it working in your guest room, I guess that would depend on the size of area you are trying to vent and shade ouside, etc. I am venting a 10X12 greenhouse in full sun and more than likely i will add another one this year.

What size hole should I cut in the roof, just purchased but no install instructions? Thank You

The base comes off. You can use a saws all to cut a hole either 9x9 square or 8 and one half inch circle. You do have to flash your shingles or metal roof around the hole and neck. Sorry I don't have picture. The square hole is easier to line up. Careful about flashing it well.

How long do the solar panels last? Will it still vent if fan no longer works?

This is the best question we have ever been asked. Thank you! Solar Blaster was born because me.. a roofing contractor had problems that were not accociated with my workmanship. Not understanding the science for particular applications being one of them. There simply was not enough air flowing thru attics at crucial times. The list of those crucial times being long and many times expensive. Even unhealthy. (Mold) What we do is take a vent that vents always work as a convective vent, meaning heat has to rise to it in order for it to work. We took that same convective vent and said the answer was to “use the power of the sun” to add additional crucial airflow to aleviate many of these problems. We said the best way to do that was to use the products roofers were already using such as can vents and ridge vents and solar power them. They would then be hybrids, they will work to meet applicable local and national codes and they would vent using the “power of the sun” in a uniform and balanced manner. Just like the architect designed. We said that using large fans circumvented that architectural design and in many cases robbed essential airflow from legal codes even manufacuters codes. In some cases voiding warranty’s. We said that several small fans doing a job in a balanced manner was correct way. Intake down low and exhaust up high. We say many more things. We are always wanting to tell you the multitudes of benefits We believe that the healthy movement of air using small fans will change the world. With todays technology we can insure a minimum of a 25 year life span. We can say that our life breathing fans will last around 15 years rated. When you buy a vent from us it will vent convectivly always 24/7 and when the sun hits it it will change the world by the movement of healthy naturally cleansing air. Think of it as your attic becoming as fresh smelling as that pillow that just came off the clothesline.
