Circuit for Solar shades for partly shaded windows

I came up with this circuit design for windows that receive partial sun so they can maximize exposure or minimize it based on the season (winter or summer). I'm not sure it works because my circuit designing skills are real rusty. I'm also not likely to use it because I am instead inventing clear quilted window covers for winter and have yes take care of summer. Correct it/use it as you see fit. If you do make money off it, I'd appreciate at least a thank you.

Oh, I guess I should say: the circuit senses light and therefore rolls or unrolls the curtain based on sunlight exposure and whether the circuit is flipped to summer or winter mode.

In theory, if I did it right.

Digging for bread-board!
