I'm making a circuit using piezoelectric discs and i wanted to attach solar panels in parallel as well in order to increase amperes of the circuit. However, when put in conjunction the piezoelectric discs seem to have no effect on the circuit, when previously they had been contributing 5 or more volts. What is happening to the piezoelectric discs, why are they not working?

Perhaps you weren't tapping on the discs fast enough.

TURN DOWN VOLUME!

In general, you can't simply connect different sources in parallel and expect them to work together. The solar panels are probably a heavy load on the high-impedance piezo, shorting them out.
