[QUOTE="pnuner, post: 2357387, member: 211"] Like jrusling said, it depends on the charge controller. Adding panels is as easy as getting a connector and plugging them in. However the charge controller needs to be sized to the wattage/voltage coming in. The one that comes with the Renology kit is rated at 12/24 volt and 10 amp input. I don't know if it could handle adding another panel. Like I said this is something I just started playing with and am really not using/depending on it for emergency power. I just had a 10x14 cellar built and wanted power down there and didn't want to rely on the grid being up during a thunder storm (it usually isn't). Like stated above you need to decide what you want to power and for how long. For me I just wanted to run some lights and a computer and or TV for probably not more than a couple of hours. Also a BIG factor is your storage (batteries) that can be easily your biggest cost. I didn't need a lot of reserve capacity so for now I'm just going to use a couple of 12 volt marine batteries. Later I may switch to 2 6 volt golf cart batteries which actually has more amp hours than the marine batteries. The more storage you need the more expensive the battery. By the time it's said and done with batteries, cable, solar panel, etc I will have almost $1,000 in my tiny system. [/QUOTE]
