Solar Lights for Sheds

I need to light a shed thats is about 10 x 12 feet, insulated and with two north facing skylights. I am an artist and normally use daylight. Heating is calor gas and I don't really need any plugs, all tools are cordless  etc. If  I need power I run a cable to the 'sheddio' which is 12 feet from the house. I have a Daylight Company battery light for close work.

And to keep it on topic, I keep my bikes in there as well.

Any thoughts recommendations on solar lighting and power sources etc? Run times may be 5 hours or suchlike?

Thanks in advance.
