A single dark-blue wafer that converts sunlight into electricity/Technology
A monocrystalline solar cell is cut from a single silicon crystal ingot and typically converts 20 to 24% of incoming sunlight into electricity. Modern cells are about 182 mm square and 0.15 to 0.18 mm thick. A standard residential panel contains 60 or 72 such cells wired in series.
