Thanks for the input gents! And yes, guilty as charged. I built the treehouse (or house in a tree as my wife calls it) for the kids but I'm living out all my childhood visions of grandeur through it lol. I am familiar with voltage drop especially for 12v but after looking at that calculator...

Thanks! Come on over, I won't charge much for rent ? I am not at all against running 120 to the treehouse from the shed. One thing to keep in mind though is I'll need to convert it back to 12v again for at least the car stereo and GMRS radio. I'd like to do the led lighting in 12v also...

Sweet! Thanks man. I appreciate you getting the info out there for the 767.

How do I do a power audit?

Okay, I realized I have a smart plug that measures power on the extension cord now. It has other things on it like patio lights and a small space heater at the moment that I won't expect the solar setup to run. That being said, it looks like I fluctuate from .01 (most days) to 5KW.h...

I am planning to head down to Richmond next week to pick one our two of these panels up to mount on my shed roof and power my 767. Thanks for the info watchdoc! Couple of questions: -Would there be any serious disadvantage (besides the obvious) to running just one of these panels? My wife...

Thanks for the input. The shed roof it 8'x6'. 400-500w (if I got that much roof mounted) for $300 or so might be hard to beat tough. Plus the simplicity of it.

Ah, gotcha. I thought you meant new panels locally. Yeah, I'd do new batteries for sure. I'm going to check FB and CR for panels now. No idea what I'm looking for really though. I guess if I keep everything in the shed, it's all close to itself and I could run the panels in parellel at low...

It comes to $366 shipped to me for 3 which is how many I could fit on my shed roof. Not sure how terrible a price that is. I'm trying to talk that local guy down on his price as he's actually wanting a little more than Santan. If I can get the panels I linked for $300 or less for 3, would...

https://www.facebook.com/marketplace/item/1003751296819620/?ref=facebook_story_share The are pretty close. Thoughts?

It does catch shadows in the morning and evening, yes. From maybe 1000-1600 it's getting unshaded sun though. Give or take. Are you saying some shade should make me look more at wiring the panels in parellel?

Hello all! I am planning to power my kid's treehouse with all 12v stuff. Actually I already am with an extension chord and an ac/dc 30 amp power supply. I currently have a 50w GMRS radio and an old car stereo with a couple of 6 1/2" speakers. Planning to add some led lighting and maybe a...

Any tips on places to look for local panels and maybe batteries as well?

I will also add it would be sweet to power some led lighting in said shed but I'm guessing that might be best having a separate system with co-located panels?

So those local ones I listed above are too expensive then? Keep looking?

I tried checking out shipping prices on Santan but they won't give you anything until you completely check out which is kinda nuts.

Just found these used local to me for half the price. Should be a little better with the 400w Qcells considering the higher watt rating and higher VoC, right?

I'm considering ordering panels from Santan united something decent local pops up soon. For the 250w panels, the size means I could fit 4 of them on the shed roof, but only if I mount them "sideways." Is there any downside to mounting them rotated 90* from the normal vertical way I typically...

Looks like Richmond doesn't have the 480w panels but they did suggest some physically smaller (which suits my shed better anyways) 400w panels also by Q Cell. The thing I worry about is the VOC is only 45v and the MPP voltage is like 38v which starts getting down towards the 32v limit...

No panels. I'll buy what you guys tell me :)

I was thinking 2 panels in parallel like a smaller version of your setup, although realistically I only need one. I figured though as long as I'm up there I might as well get all I can.

I'm in northern VA not far outside DC. And according to the power supply I currently have getting 12v from the extension cord, it says I'm currently using 10-15amps with both the stereo playing music and the GMRS radio transmitting which it does rarely. I'd like plenty of overhead though...

Ahh, just figured it out. Solar charge controller. Maybe 40 amp and more panels is better?
