Silicon Solar Panels

These rigid panels come in two types: monocrystalline (made from a single large crystal) and polycrystalline (made from blocks of silicon that contain many small crystals). Silicon solar panels are the most efficient on the market but also the most expensive. They are also the best-performing panels in lowlight conditions. Although polycrystalline solar cells are slightly less efficient than the single-crystal type, National Renewable Energy Laboratory (NREL) has measured silicon solar panel efficiencies from 20% - 25% in laboratory conditions. However, South Carolina utility experience suggests normal expected efficiencies of about 16% - 18%.
