I haven't seen much info about this really on the web. I want to know if it's possible to use a tilt kit on my north facing roof. I live in a small cabin I bought with a shed roof that faces north. The lot is very wooded and I could not ground or pole mount without significant tree removal that would drastically change the "woodsy" feel of the property. I only require a very basic solar setup as I'm pretty minimal (propane fridge, wood stove for heat, just need to run electronics and if possible tools). I want to know if it's possible to use a tilt kit to mount a few solar panels and get the electricity I need.

gxnthr,

You're not giving us much to go by.  It would depend on how steep your roof is, and how many rows you can install without obstructing the view of the sun from the other panels.  I would imagine for the power demand you are talking about, having a row of panels tilted up at the sun and running the length of your roofline would serve you well. Two, three, maybe four panels?  how big is your shed and what is the length of the roofline?

I will get you some dims and a pic tomorrow. The shed is my cabin - just has a shed roof on it. I guess a lot of people advise against reverse tilting and I can't speak to how well the cabin is constructed as it's a small (but not tiny) basic cabin in the sticks without code.

I suspect it is possible. It make take some creativity on your part that extends beyond a kit.

Yeah I'm hoping so. We're on the grid and would love to be off. But even more urgently - I recently purchased this property with other folks. My cabin is shoddily daisy chained to another cabin (with interior wire just laying on the ground lol) on the property and it's obviously not getting the power it needs and probably has questionable safety especially once I get all set up in here to live for the winter. I have some very basic electrical knowledge enough to set up solar under ideal conditions but I'm a little overwhelmed about this project / if it's possible (for me).

This thread might give you some insight:

Do you have a sunny spot where you might use a setup like this:

A shed roof that slopes down towards the north? My first thought would be to use a wall mount rack on the south wall up high and create a sort of overhang with the array. I've used a 3x60 cell rack in just such a way... Worked great.
Cheers,. David

My cabin is 24'24' ish with I think a 45 degreeish pitch roof. Attached are pics (just bought this cabin very much a work in progress right now). Will look at the thread posted above and thanks for the tips!

The pictures help. Based on past experience and your location I would mount two 60 cell panels between the two second floor windows on an adjustable rack. I would definitely suggest you get a good mppt charger as the cheap pwm units won't produce much due to shading. Winter will be the tough one  assume about 1.5 hours of charging in the winter and probably less then 50 percent available light so 0.75x your array size will be your daily production; so not much. Ideally you would back up that south treeline maybe replant with some smaller trees to maintain the wooded feel of the property it would help.
Cheers,. David
