Quote from: Squirl on October 18, 2011, 08:33:02 PM I was just curious. I know it has been something I have been dealing with at my site and I'm just a little south of you. In the winter the angle is at 27 degrees.
Quote from: Squirl on October 19, 2011, 07:03:28 AMIt isn't the panel angle I have to worry about, it is the trees. At the angle for the winter the tree's shadow is double its height. In addition the back part of my property is pine which don't give up their brush in the winter so no sun would get through if I put the panels to close to the trees. Each foot taller I place the panels equals 2 ft closer to the tree line I can put them.
Quote from: Squirl on October 19, 2011, 10:31:32 AMI think I found the solution so far, I just have to make sure I implement it correctly. My house is currently around 125 ft from the tree line. I also have around another 50 ft closer to the road that I can play with. If I put them up 10 ft with a large base the trees can grow to 100 ft without effecting it. Within a few years I will try and remove the trees. Pine, especially the ones I have, are generally worthless and I would rather have fruit trees anyway. Wind will be more of the primary source in the winter but because of cost and inspection issues I will probably only have solar and generator power for the first year. I just thought I would share some of my issues because it looks like you have a similar setup. How far is it to the tree line for you?

It might also be a good idea to use a larger diameter pole than you might need for the planned current installation. A larger pipe could then be used for a future expansion. Dave Sparks who comes and contributes here uses nothing less than 6 inch pipe for that reason, IIRC. Look for used drill pipe, it can be found in many places at a fraction of the cost for new pipe. That's what I have in 4 inch, 1/4" wall, 4 1/2"OD. You don't want the wind blowing it over.Not sure I would depend on a threaded connection. Pipe can be had in up to 20 foot lengths.Unirac's info can be found here.

Quote from: PorkChopsMmm on January 03, 2012, 09:26:38 AMDon, how are your batteries holding up to the cold? Mine are in a similar type enclosure and uninsulated. I think the cold is hitting them hard because they seem to have lower power output then in the Fall. I am thinking of putting some rigid foam around them to help hold in the heat they generate from charging.
Quote from: cabingal3 on December 27, 2011, 12:04:37 PMmaybe someone can answer this question for me....when we went to our cabin this weekend,all my oil lamps had frozen fuel in them.If i lit one-will the glass that holds the lamp oil break?? or should i wait for the oil to unthaw???
