Solar energy and photovoltaic systems

Solar explained

Solar photovoltaic systems. Solar photovoltaic (PV) devices, or solar cells, convert sunlight directly into electricity. Small PV cells can power calculators, watches, and other small electronic devices. Larger solar cells are grouped in PV panels, and PV panels are connnected in arrays that can produce electricity for an entire house.
