Living off-grid in a modern domestic (and home business) environment requires more than a couple of candles and a deep cycle battery to keep a miniature fridge cold. So it was for me, when we couldn't practically get a grid connection here. Our propane powered generator kept the batteries charged, but with propane costs going up all the time, it was getting to the point I had to put on more solar than the small, token effort I had (4 x 75W panels). So, with some trepidation, I researched, ordered and paid for some 100W PV modules from a supplier in China. (Less than 1/4 the price per watt - including freight - than the local thieves wanted).
I was somewhat worried when they brought them out for me (I had to drive to the big smoke to pick them up from the wharf)
When I got home, I had to unpack one to check they were intact. Phew! They were packed well and all were fine.
Now that I had the panels, I needed something to hold them. I designed up a "stackable" linear array that I could put some panels on straight away and extend later as I could afford more. I decided to make it so I could "re-use" one of the posts from a previous project. (I should write up about the Traxle, too!)
So here I've dug the holes and just setting out the 4 posts
I drilled holes in the posts for the support rail to go through, and took some care to make sure they would all line up
I welded mounting tabs on one end of each rail
All the bits layed out on the ground. Everything measured and pre-drilled so it should just go together. I HOPE!
Next morning carted everything up the top and assembled.
The linear actuator that sets the angle (seasonal adjustment) went on next.
The rails earlier mentioned mount to the frame and just "sit" in the posts. The end two sit in the post, the middle two go right through.
Then it's time to start putting the panels on.
Finished. Who's for a beer?
