PVpanel Sim is a spice simulation utility for two dimensional simulation of thin film solar panels, using the conventional equivalent circuit for individual cells. The tool incorporates the variability of shunt conduction from cell to cell, and effect of sheet resistance of contact material. This allows the user to assess the gap between cell and module efficiency in thin film technologies. The user can change the distribution of shunts from cell to cell, and vary the contact sheet resistance to understand their effect on panel efficiency. Another feature of the tool allows the user to analyze the effect of partial shadowing the panel due to nearby object in full 2D. The tool calculates the reverse stresses generated on the shaded cells, based on the user defined breakdown characteristics. The second version of this tool adds the capability by adding an enhanced non-linear equivalent circuit more suitable for thin film solar cells.
