A reliable photovoltaic (PV) power system is provided, including a plurality of smart virtual low voltage PV modules arranged in a plurality of columns and a plurality of rows. The smart virtual low voltage PV modules on the same column are connected in series. The smart virtual low voltage PV modules on the same row are connected in parallel. Each of the smart virtual low voltage PV modules comprises: one or more photovoltaic cells, configured to convert solar energy into DC power. The system further includes a DC/DC converting unit, coupled to the PV module, configured to communicate with a control center to acquire from the control center a determined level value, thereby converting the DC power received from the PV module into a demanded output voltage having the determined level value.
