solar PV cells (Mode 1)
Type of solar PV
Poly-SI
Model (manufacturer)
Poly-SI-TSM-PC05 (Trina Solar)
Efficiency
14.4%
Nominal operating
temperature
45 °C
Power capacity/panel
235 W
Power capacity
32.9 kW
Number of panels
140
Total electricity exported 55.205 MWh
Solar collector area
233 m 2
In this mode, all the energy needs of the industry are suggested to be met by solar
PV-based electricity connected by grid instead of grid-supplied electricity.
The analysis of this mode is done using RETScreen software, which allows the
user to estimate the cost to meet the energy requirements by various renewable
sources of energy and also estimates the carbon savings against the conventional
grid-supplied electricity. The software also enables the user to calculate the payback
period of the investments made.
The details of the solar panels to be installed to meet the complete needs of energy
are shown in Table 9. To generate about 55 MWh in one year, 32.9 kW of poly-Si
solar panels will be required based on the needs of industry and solar radiation of
the region. The analysis suggests that 140 units of 235 W solar panels with 14.1%
efficiency will be required to fulfil the energy requirements. The total area required
to set up solar panels is around 233 m

generation at the location of industry on the basis of weather conditions of that
location around the year.
