A Hybrid Solar Tracking System with Photovoltaic Cells and Thermoelectric Module
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Conventional sources like fossil fuels were used in early stages to satisfy the energy demands. Nowadays these are slowly replaced by renewable sources like photovoltaic sources. Solar PV is starting to play a substantial role in electricity generation in some countries as rapidly falling costs have made unsubsidised solar PV-generated electricity cost-competitive with fossil fuels in an increasing number of locations around the world.Solar cells, also called photovoltaic (PV) cells, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called thePV effect. Today, thousands of people power their homes and businesses with individual solar PV systems. Utility companies are also using PV technology for large power stations. Solar panels used to power homes and businesses are typically made from solar cells combined into modules that hold about 40 cells. So this paper describes the design of a hybrid solar tracking system made with photovoltaic cells and thermoelectric modules which is the need of the hour. Assolar energy is a renewable heat source freely and widely available everywhere, outdoor performance of photovoltaic (PV) modules suffers from elevated temperatures. Conversion efficiency losses of up to about25% can result, depending on the type of integration of modules in the roof. Cooling of modules would therefore enhance global performance. Instead of module cooling we propose to use the thermal waste by attaching thermoelectric modulesat the backof PVmodules, to form a PV–TE hybrid module.
