Choose Used Solar Panels
Used solar panels can
be a great bargain for property owners who are interested in adding a low
cost means of generating green electricity for their home.
Although used
solar cells can be a wise choice, they also come with many
disadvantages. These disadvantages mainly relate to the uncertainty of how
long the solar cells will last (due to their age).
Estimating the lifetime of a solar cell can be a complicated task. This is
mainly down to the fact that some of the earlier solar products are still in
use today. Some cells outlive their stated lifetime range (which is usually
around 30 years), and as new solar technologies are brought to the
marketplace, who knows how long these products will last.
Older cells generally take up more space per wattage than modern day solar
cells. This can be an issue for home owners who want low cost second hand
solar panels, but don't have a great deal of space to accommodate their
desired capacity.
If you purchase used panels, then you also run the risk of purchasing
damaged panels. Try to avoid second hand solar panels which are; cracked,
scratched, appear to have condensation under the surface, or have
brittle/loose connections. Although these problems can be fixed, a good
quality used solar cell should give you less of a headache.
There is no doubt that used solar panels have the potential to save a
significant amount of money for the
financing of a renewable energy project,
however, the above disadvantages of used cells should be taken into account.
Depending on your location, a
solar electricity installation may not be
economically viable due to the climate and surroundings. Solar cells are
generally less efficient in hot climate countries (as heat degrades the
performance of solar cells), polluted areas (such as
cities), and in areas where there is a low average of daylight hours.
