Anyone know where I can get a solar photocell switch that can do the reverse of normal types? I would rather not use a time switch, but as this is to control a fountain which I want it off during the night and on during the day.
normal solar switches have Live / Switch / Neutral so there is no connection for on at dark.
Yes there are many types of solar cells that can go on or off depending what type you use and some can be wired either way. Find an electrical /electronics industrial supply store. They should have something for you.
