    Solar Install with Net billing with Utility

    Portable power pack

    I have a shop full of tools that are mostly plug-in electric. But from time to time it would be nice to have a battery operated tool for areas where you have no electricity. Instead of buying battery operated tools I thought it might be nice to have a portable power pack for those occasions when...

    12V vs 24 volt

    My motorhome is all 12 volts.Is there any advantage (ignoring weight and size) to using one 200AH 24 volt battery and step it down to 12 volts or use 2 100AH batteries. Is there an efficiency loss going from 24v to 12v? Thx

    Stacked Panels with a slide out feature when parked.

    I would build a frame that allows you to stack 3 panels high.The top panel wolud be fixed and the second and third one would slide out to the side(one to each side).Use heavy duty drawer slides..If you can;t weld the frame then use 2X2 angle aluminum which is easy to drill etc. You can devise...

    Airstreamer looking for some advice on mounting to a curved roof

    Seeing as how the problem seems to be air getting UNDER the panels to severe the connection (of any type) why not put an aid deflector at the leading edge of the panel forcing the air over top the panel. Like this (https://oriondesigns.ca/)

    8p1s vs 4p2s PV wiring?

    . "My preference is to put as much in series to make for easier wiring, with smaller wire." I may be missing spomething here(likely) but from my experiencewhen installing my own 12v solar on my motrohome the extra cost for hevaier wiring was probably less that $5.

    Drilling Through RV Right (Curbside) wall

    I would use the hole saw size you need and drill the hole from the inside. If you hit a structure piece it is easy to put a patch on it. At least easier than from the outside. Your getting pretty close to the window frame so there is a good chance there is a structural piece there.

    Off grid solar system for maintaining half a dozen batteries (ATV's, tractors, boats, etc).

    So you get snow.It doesn't snow every day (just like its not cloudy every day) And when it snows brush it off. (which you can't do with clouds) and the sun may be low in the sky in Manitoba but there generally is lots of it.

    I have a barn that has metal over shingles on purlins and don't think you want to just fasten the rails to the metal.
