- mena661ExplorerThe biggest space I have is roughly 120 x 60 (maybe a bit smaller). Two panels just barely squeaks in there and would be in a shadow at some point in the day. One big panel would fit and be short enough to move around to the best spot. If I used the other locations on the roof, I would need a lot smaller panels to fit. I'll probably end up with the Rogue 30A (especially now that they included the data converter for free). That should allow one big one and maybe 2-3 small 12V's in series if I wanted to expand.
- BFL13Explorer IIMy 130w 12v panel is 26.1 by 59.0 Three of those side by each is 59 by 78.4.
Series with MPPT or parallel with PWM or MPPT - mena661ExplorerCant fit two 250W panels BFL.
- Argosy24ExplorerThe MX panels are sold out.
- BFL13Explorer III see the Sharp is 39.1 by 64.6 so two would be say 79 by 65.
Scroll down for specs here---ignore the crazy price she is asking "up here" :(

One thing with two 250s is you could go with two $100 MPPT controllers. Not sure what you would pay for a single controller that can do the big watts. - mena661ExplorerEsoxLucius,
Thanks for that link. I wanted to put two 200+W panels head to toe but it would be a squeeze so a single 77" long panel will fit easily. And I have 60" of width available so no problems there either. - EsoxLuciusExplorer

I have and I'd really like to get a 300+W panel but can't find one (I wonder if SB could get one...when I'm ready to buy I'll ask them). I have an unusual roof in that I have space for one really big panel and maybe some really small additional panels so I'd really like to make that big space count. I might settle on the 250W Sharp that SB sells.
Room up there for 77.2” x 51.5”? 390 watts http://www.grapesolar.com/specs-390w-mono-gs-s-390-ts.html http://www.freecleansolar.com/390W-solar-panel-Grape-GS-S-390-TS-mono-p/gs-s-390-ts.htm http://solarenergypanelslink.blogspot.com/2012/01/grape-solar-gs-s-390-ts-390-watt.html http://www.homedepot.com/p/Grape-Solar-390-Watt-Monocrystalline-Solar-Panel-GS-S-390-TS/202959964#.UqjR_LRbtSQ Home Depot wants too much for them, but at least you might pick it up. - Argosy24ExplorerMX solar went out of business in June of last year. There probably isn't any warranty. I'd at least check what option you have if you receive any DOA.
Also note these are 24V panels, you're going to need a fairly expensive MPPT charge controller if you plan on using them on an RV. - mena661Explorer

Have you looked at the newer higher watt panels? They may give you better harvest density if your roof will accommodate the size. For price, it will be hard to beat SB's $.67/watt. - Ron3rdExplorer III

Odd that the panel weight is 48.5 pounds but the shipping weight is 130 pounds. That is a heavy crate.
It's probably UPS Oversize rate. In an oversize situation, you pay for "dimensional weight", not actual weigh. That's how you can have a very large 10 lb package and be charged 70 lbs by UPS once you punch the dims into the shipping system.
