I can only presume you are trying to make plans for a modest supply of electricity from a solar panel on the shed.
I have read stuff on the net about home brew systems using a panel to charge a 12V or multiple 12V car batteries (in some cases free ones from the scrappy or your local motor faactors) that then go on to power 12v LED lights and a small stereo. Unfortunaely i do not have the links on my work PC.
I would really think you would struggle to set up a system to power any high drain electrical items.
I have preiously though of doing this but have never had the time or money to do it properly – not that it is necisserily going to cost alot but i am still in the process of decorating my flat and my man cave has been put on the back burner till i get the living room sorted.
