My power source is far away. Trenching would be crazy expensive. We got quotes from solar “companies”. They were all over $2000 and they wanted to panel one half of the entire run in roof. Our fan runs as soon as the sun comes out in the morning and regardless, I have the thermometer control so if it’s not 80 degrees it stays off. It does run on overcast days so it must save up power. I don’t want/need it at night. Luckily my run in is in a breezy area and has 3 windows. I was more concerned with cutting down on bugs and flies and it’s working well. I feel a breeze on my face from it and I’m alot shorter than my horses so I know they feel it too. $600 was way better than $2k or more and didn’t tear up my pasture. So don’t knock my fan![/QUOTE]
I was not “knocking” you fan. Nothing personal in my comment. I was merely pointing out facts. So others can make an educated judgment call.
I put my first “off grid” solar power system in a cabin in Colorado in the late 80s. I am not an expert but have a better than average understanding of how these things work and the cost of. I am fairly well versed in the “nuts and bolts” and what someone should expect for money spent.
Yes, a fair amount of power will be generated on a cloudy over cast day. More than most people realize.The amount “captured” depends on the quality and size of the solar panel and its position to the sun. We had to constantly monitor our power usage and battery charging. Didn’t exactly have a lot of money to work with and MacGyvered a lot of things. A system back than cost a lot more than they do now. But it is still very expensive.
The fan you installed does a very decent job for the money. If you are happy with it fine. Others may be very disappointed with its performance. I gave industry standard numbers to put things in perspective. The standard fan that most people use in their barn a box fan moves over 3,000 CFM of air. Your fan only 1,000 under the best of circumstances. A big difference. You did not say where you are located and what type of weather you are dealing with. In my neck of the woods it can be just hot and muggy at night as it is during the day.
You said “Wish it were a stronger fan”. Which is why I tried to put things in perspective using “numbers” for others to take into consideration.
“It moves at about the speed of a ceiling fan on “high”.” Not trying to be snarky but this is kind of like comparing apples to oranges. Your fan is 18"X18" a small ceiling fan is 48". The blades may “spin” at the same speed but there is a big difference in the size of the blades and how much air they can move. Again, just trying to put things in perspective for others.
I installed 1200 feet of direct bury 12-2 wire for around $600. Being a farm I did not have go to to the expense of using a contractor to trench it. I know where it was going so there no worries about someone accidentally digging it up. It’s my farm and no one is going to be doing any work on it with out me knowing. I rented an inexpensive shallow trencher and it didn’t take very long and left little to no damage to the ground. Wired it to the barn electric panel. Very simple to do. I can power multiple fans 24/7 a light and in the winter run a tank heater.
This may or may not suite the OP. But I don’t post/comment just to address an OP’s question only. I try and present the big picture and or others ways of going about things. For the hundreds of other people who read these threads also.
