The University of Gothenburg has launched
a revolutionary tool that can determine the highest possible magnitude of solar
incidence on a roof, a town or the whole city. The scientists have used the
city of Gothenburg for this pilot project. In this regard, the University of
Gothenburg has partnered with WSP consultants to develop this GIS system,
called ‘SEES’ ( Solar Energy from Existing Structures) that can actually
measure the potential of solar roofs to produce solar energy from the panels.
The model works on the principle that
certain roof structures may or may not be suitable for use of solar panels.
This depends on the incidence of sunlight the structure receives and how much
is shadowed by the surrounding buildings and vegetation. In simple words, solar
panel efficiency (expressed as a percentage) quantifies a solar panel’s ability
to convert sunlight into electricity. Given the same amount of sunlight shining
for the same duration of time on two solar panels with different efficiency
ratings, the more efficient panel will produce more electricity than the less
efficient panel.
Using the tool developed by the University
it will be actually possible to know the amount of solar energy that can be
produced by a solar roof in a specific setting. Solar panel efficiency is calculated
by the production of electricity by solar cells, which are in turn influenced
by their composition, electrical configuration, surrounding components, and
more.
SEES is based on the GIS system
(geographical information system). This system collects, stores and presents
data. SEES can be used to show real solar roofs in correct surroundings. The
pilot project has used the city of Gothenburg as its primary model but the same
can be applied for municipalities where the data is available.
Many consumers and people in the solar
industry consider solar panel efficiency to be the most important criterion
when assessing a solar panel’s quality. While it is an important criterion,
it’s not the only one to consider while you evaluate whether to install a
particular solar panel. Solar panel efficiency relates to the ability of the
panel to convert energy at a low cost and high supply rate.
