of electricity (Figure

). This is the current,
the strength of which determines how much
electricity each cell can produce. The voltage of
the cell is determined by the material, and solar
cells also have an internal resistance to consider.
Not 100% of the energy from the sun is converted
to usable power by the cell; some light is
reflected from the surface of the cell, or blocked
by the metal lines on top of the solar cell that wire
the cells together. Other factors like shade and
sunlight intensity also affect the actual output of
the panel, even if it has a particular rating.
