FYI Basic Solar Kit from Costco
Seems like a good DIY deal with all you get. 4 100w polycrystalline panels, 2000w PSW inverter, and looks like a Xantrex Trace C35Amp controller. http://www.costco.com/.product.100111497.ht...

Running the inverter at full output of 2000W would require a 200 amp battery draw. If this would be a 24/7 situation, you will need that shed stacked with batteries and more modules to deal with the daily use, in the neighborhood of 5K AH. The wiring bill will be a face-slapper, too.
Here's the thing though, you won't be drawing 2000W 24/7. My house doesn't use that much power 24/7 and we are electrical pigs.
FWIW, I run a small 120V dorm fridge in my rig using a 235W module and 300 AH of storage. The fridge draws 80W when running and normal duty cycle is 1/4 -> 1/5, depending on ambient and use. A larger double door fridge will draw 1KW, daily. about 100 AH. The costco kit is rated to charge back 100AH and you'll need enough battery storage to make it through days of less sun. If you wish to use more devices, you'll need more module and more storage.
Here is a Downloadable spread sheet calculator that will tune you in to use and storage numbers.
