Skylight blinds

[Matt]

Hey all...

There are 3 skylights on the upper floor of my house, with no access for
pulling wires, etc. to them

HOWEVER

I will be having the roof replaced soon, and this will provide the access I
need.

Can anyone recc. some power blinds, and if they require 110 or low voltage
power?

Typical skylight size, about 1.5' x 4.5' (roughly). Looking for remote
controllable, and/or self automated to tilt as the sun hits them.

I'd prefer to be able to retract them horizontally, but if all that can be
done is to open and close the louvers, I could live with that.

The reason for the power question is it's a high ceiling, and I don't want
to be changing batteries/etc.

Thanks
Matt
