Re: [RE-wrenches] Ideas and racking systems for "stowing" ground mount PV array during snowy winter?

I have seen repeat melting and freezing rip the frames from the modules, granted these modules were not sealed or glued in. But just consider if water can get in a rail and freeze then any extruded frames with inclosed channels can be effected. Option is to drill the boxed channel to promote

Hey Michael, Any chance you might share a couple of pictures of the project you discussed? Christopher On Sun, Mar 27, 2022 at 11:44 AM Michael Morningstar via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > We almost always use the AES brackets. Often mounted to strut. You want >

Hello, Sorry to be so late but I have been overloaded. Just a note on physics of lifting water. The calculation indicates if you pump 1 gallon per minute up 300 feet it required a water hp of 5 HP Use this base number and good pumps are about 70% efficient. If the flow rate is not 1 GPM adjust

Hello Wrenches. Contact me off list with any questions or concerns. I'm experimenting with new list server settings, as google had recently been rejecting list messages going to gmail addresses. I think I've got it mostly squared away, but have a couple of concerns I'm figuring out. As I've

Good afternoon; Mounting modules on 3 rails will typically increase the load carrying capacity of the array by 30% (or more). Most module manufacturers list this method in their installation manuals, or if not in the manual, they have a waiver written for that method. Be aware that when

Hi Blake, I'm curious why the assumption that the snow will destroy the array - how about 3 rails instead of 2 under the modules? Blake Gleason via RE-wrenches March 26, 2022 at 8:39 AM Hi all, I think there's a lot of experience on this list with

We almost always use the AES brackets. Often mounted to strut. You want access to the on/off button, so some exposed conductor is inevitable. We have also fabricated shelves for them to sit on. For 2 or more batteries in multiples of two, we stack them so that the bottom battery has its terminals
