Renewable technology being more affordable has become the choice of various individuals and nations. The countries adopting to the renewable energy should include the expected lifespan of the equipment, cost of initial equipment and installation and finally the availability of renewable energy sources in the region into their checklist.
Purpose of Statement
The case study is organized as follows:
Chapter 2 gives a brief on the solar water heating system and its functioning
Chapter 3 gives a brief on the solar energy collector and its functioning
Chapter 4 gives a brief on the solar thermal power system and its functioning.
The history of the solar energy started way back in 1860s which was driven by the fact that coal was expected to be scarce. But it was in early 20th century that the development of the solar energy and related technology came into play due to the increasing availability, utility and economy of the coal and petroleum. The development of a rooftop solar and the utility-scale photovoltaic power stations were seen to increase to the high demand and supply issues of the oil as well as natural gas, improvement of the economic position of the PV and the global warming concerns. (Sarver, T., Al-Qaraghuli, A., & Kazmerski, L. L., 2013).
Below are the various solar powered utility-scale equipment:
Chapter 2: The Solar Water Heating System
The solar water heating system are also known as the solar domestic hot water systems which is a cost effective method for generation of the hot water. As they are solar powered they can be used in any climate. These solar water heating system are equipped with a storage tank and solar collectors. These solar water heating systems are of two types namely active and passive. The active ones have a circulating pump and control whereas the passive ones lack these. The household water is pumped using the collector in the direct circulation systems whereas the water is circulated in a non-freezing, heat-transfer fluids using the collectors and a heat exchanger. This heated water is then used for the household and other purposes. (Fanney, A. H., & Dougherty, B. P.,1994).
Chapter 3: The solar energy collector
The device used for collecting, absorbing and transferring the solar energy to any working fluid like air or water are called the solar energy collector. The solar heat being collected can be used for heating water, or for heating the swimming pools and for backing up the heating systems. The solar collector has an absorber which is composed of various metal strips. The fluid present for the heat transfer flows from a pipe which carries heat and is also connected to the absorber strip. Whereas in the case of a flate-plate absorbers, two sheets are sandwiched so as to allow the medium to flow in between the sheets (Chang, K.W., 2008). Some of the solar collector include:
Batch collectors, Glazed flat-plate collectors, solar cooker, unglazed flat-plate collectors etc.
Chapter 4: The Solar Thermal Power System
The solar thermal power plants are used for heating a fluid which is circulated through the pipes. The steam so produced is then converted into the mechanical energy in a turbine which is useful in generating the electricity. The Solar thermal power generation also work similar to the power generation being run by the fossil fuels but in these have combustion of the fossil fuels instead of the steam. A concentrator system is used by the solar thermal technologies for achieving the high temperature required for production of the stream (Singh, N., Kaushik, S. C., & Misra, R. D., 2000).
