Photovoltaic solar energy is a clean form of electricity production. The research and
the technological development that is done in this thesis makes possible an
introduction of this technology in the production of electrical energy in the world to
complement the existing sources of conventional energy.
Stand-alone photovoltaic systems are a set of interconnected elements to provide
power to a given load, the relevant photovoltaic modules are choosing for their
performance, because, they are the key to the power generation system works and
therefore presents the technology for manufacturing photovoltaic cells in industrial
environments. Most solar modules are currently produced from silicon cells. Silicon
is the most abundant material on earth, however, required to undergo a refining
process by growing a large crystal (monocrystalline or multicrystalline) and then
cutting it into this slices which are 0.3 mm thick, this slices are the base material of
photovoltaic solar cells. Traditional production of silicon is expensive and highly
demanding of energy, in fact, during the cutting process lot of material is wasted,
near the 20% in the form of dust. It is also very expensive to recycle this residue, but
there are specialized methods to prevent this waste, developed countries continue to
investigate ways that minimize the waste of material. However, today's silicon solar
cells are dominating the market, accounting for about 90% of the modules that are
manufactured in the world.
Photovoltaic systems depend on many factors that will determine the best or worst
use of solar energy incident or, what is the same, the system performance. For
measuring this parameters, a simple way of estimate the number of solar panels
needed for the power of 5000 watts required in this project, which involved as the
main point average solar radiation of the installation (Pichincha in our case), the
voltage level panel and power used, is shown under the criteria detailed technical and
economic feasibility for the best option. |
