Description:
A photovoltaic (PV) cell,
also known as a solar cell, is an electronic component that generates
electricity when exposed to photons or particles of light. A
photovoltaic system employs solar modules, each comprising a number of
solar cells, which generate electrical power. PV installations may be
ground-mounted, rooftop mounted, wall-mounted, or floating. The mount
may be fixed or use a solar tracker to follow the sun across the sky.
Efficiency is the ratio of electrical power produced by the cell to the
amount of sunlight it receives. To measure efficiency, the cells are
combined into modules, which are in turn assembled into arrays. The
resulting panels are then placed in front of a solar simulator that
mimics ideal sunlight conditions: 1,000 watts (W) of light per cubic
meter at an ambient temperature of 25°C. The electrical power produced
by the system, or peak power, is a percentage of the incoming solar
energy. If a panel measuring one square meter generates 200 W of
electrical power, it has an efficiency of 20%. The maximum theoretical
efficiency of a PV cell is around 33%.
This is a 12V photovoltaic
solar panel, providing 20W power that is greatly useful for the DIY
small project. The size of this panel is 520mm x 240mm x 17mm which
includes the frames.
