The invention provides a high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. A front surface metallization pattern on the solar cell may be configured to enable single step stencil printing, and an overlapping configuration of the solar cells in the super cell facilitates the single step stencil printing. A solar photovoltaic system may include two or more such high voltage solar cell moduleselectrically connected in parallel to each other and to an inverter.
