2. ¿How function this energy?
Change sunlight directly into electricity.
Individual PV cells are grouped into
panels and arrays of panels that can be
used in a wide range of applications
ranging from single small cells that
charge calculator and watch batteries,
to systems that power single homes, to
large power plants covering many acres.
4. Advantages:
·The photovoltaic panels are clean,
silent and don't demage the
enviroment.
·They save many energy.
·They are built very fast and they
have a minimum maintenance.
·We can use this system when there is
Sun and when there isn't Sun.
·
5. Disadvantages:
·The cost of these panels is high.
·They aren't pretty.
·When there isn't Sun, you can only
use the accumulate energy.
6. Disadvantages:
