i have been skiddish of solar power, here in central, IL. mainly due to the winters, when batteries will be the weakest, and the least amount of sun to be had. not to mention batteries freezing solid up in winter.
majority all sheds around here use metal / tin sheets, any were from 2 feet to 4 feet wide, and up to 20 to 30 feet long. you can normally find the pattern these sheets come in at the large local hardware stores. and insert some clear panels for lighting. if not a local company that builds metal shields should be able to get you the correct pattern that will fit the metal / tin sheets you have on the roof.
have the "sky lights" errr clear panels in both sheds here, and make things bright enough to see fairly good. exception in the dark corners. or when ya in your own shadow looking at stuff along the sides.
night time on other hand. is a different story.
==============
if you are wanting actual power out to the shed, contact your local electrical company, and see if they may make some sort of deal with you. to run regular power poles out to the shed, to set a meter at shed.
along with contacting a couple other electrical companies, to see what it would cost, for owner installed poles for a meter at shed. or like.
some times there are discounts, some times there is not. that can make running regular electrical power a distance a possible running over other off grid options.
