Water recycle project no.1

[Percy]

Help please if you can.
I am looking for a small solar powered water pump to pump to a min. of 1.5bar. The idea is to set the suction into a permanant position into the bath. The pump will then hopefully be connected to the inlet of the toilet cistern to fill for toilet flushing. I have already managed to plumb the cistern with the inlet connection and a back up to mains water with a double check valve to prevent back contamination. The problem I have is where to get the pump and panel from as it will not always be in direct sun light. Any ideas please?
