A booster for PHOTOVOLTAIC (PV) panel output power utilizes the low output voltage generated by the PV panel during none optimum operating conditions, to enhance the power output level of PV panel. The booster module described, in the exemplary embodiments of the present invention, operates only on energy provided by the PV panel that is connected to, and does not require any other source of energy. Booster operation is implemented such that, when booster is disabled, during normal PV panel output levels (50% to 100% of a PV panel rating), it does not adversely affect the PV panel efficiency.
