You may continue to use it at 5V if the energy extracted from the PV is drawn via a MPPT ( maximum power point tracking) IC and your solar panel assures the current needed for your electronics. Many panels have 6V open at 0.3A or 0.5A short circuit current Actually any actual PICmicro will run on 3.3V ( including those rated for 5V) if the internal oscillator is set to maximum frequency intended only for 3.3V. Most of the low power PICs ( LF series) will run down to 2.2V ( some down to 1.8V) so you may connect the solar panel directly on your LDO without MPPT or PWM. best wishes
