I think ov installs average about 5-7 dollars a watt. Diy can probably get it down to half that. He needs to figure out what kind of load hes gonna put on there - a single 4 foot led strip light from costco running an hour or two, you can cobble something together with a 100-200 watt panel, charge controller, deepcycle battery, and 1000 watt inverter, doing the same with a half dozen 160watt high bays? Not so much.

Run a wire. And Pluto is and always will be a planet.

I know that Pluto identifies as a planet. Who am I to say otherwise?
Note to self: start reading sig lines. They're actually quite amusing. :D

Grab one of these: https://www.amazon.com/Renogy-Watts-Vol ... olar+panel

Add another panel or two, two deep cycle batteries and an inverter.

thanks guys.

Is it worth it to build panels from scratch for the savings or are the premade ones that much more durable reliable?

I am thinking getting 300 W of panels from DIY panels self assembled, then an inverter... and 2 deep cycle batteries run at 24 volt. But will plan out the system better once I get my stuff at home.

This will be a good test case for both he and I. He wants to build a bigger array later for SHTF and other items. Living on 10 acres surrounded by not a lot of residential makes it enticing for him.

How far is it from the house to the shed?

from the box to the shed, 100 yds or so.

Run as a 12 or 24vdc RV setup?

Shop craiglist and ebay for stray panels. Surprisingly cheap can be found at times.

Battery and controller could turn out to be the largest expense.

My thoughts on PV (Keep in mind that I am an engineer on the NPV side, not a consulting engineer. However, we make a lot of components that go into PV systems, etc - mostly on the utility level rather than residential, but some of that too.) I do occasionally go vote on the NFPA stuff related to it too.

1. I am mostly not a fan, but it has it niches.
2. I would never put solar panels on any permanently occupied structure (like my house).
3. Putting it on remote or out buildings is probably okay (so your friend's application is potentially okay in my book).
4. Don't go too cheap, some of the crap from China and whatnot is dangerous IMHO.
5. Make sure you put an emergency disconnect that is well marked and accessible or the fire department will let your structure burn to the ground if the see solar panels on it (they may anyway, but at least you have a shot at them doing something.)
