Very good Dev. A shed definitely needs power. You won't know yourself now, especially once you go a step further and spread some more powerpoints and lights around, which is relatively easy now that you have the board in the shed.
Another thought which may apply to your situation, with your nice old heritage house. I've put off getting solar panels at my place for years, mainly because I don't want the ugly things spread all over my roof, but I recently had them put on the back side of my shed roof - something I could do because I already had a sub board down there.
The result is that it's virtually impossible to see the panels from the street, or anywhere on my property, and also the control panel is above the door (inside) of my shed, rather than attached to the side of my house. All very neat and tidy
