Application of halved size cells in photovoltaic (PV) modules is an efficient way to reduce the cell-to-module loss and increase the module power. In this work, the difference between halved size and full-size multicrystalline silicon solar modules were investigated from two aspects. The electrical parameters difference between 144 halved cells and 72 full size PV modules with same material combination was experimentally studied. It was found that the power increasing of the halved cell PV modules was above 9 W compared with the full size cell modules, the Imax increase of the halved cell PV modules was 1.16%, and the Isc increase of the modules was 1.32%. Furthermore, the electrical parameters under different shading conditions and different shading cell areas for halved size cells PV modules were discussed. The results showed that halved size cells PV modules have better performance under different cell shading conditions than full size cell modules. The Vmax of halved size cells module with 90% shading areas decreased to 2/3 of that without shading.
