SUMMARYThis paper presents the analytical study of flat plate collector based on the computer-based thermal models considering two different cases, case A (fully covered by glass) and case B (fully covered by photovoltaic (PV) module). These models are developed based on energy balance equations. An analytical expression for characteristic equation for photovoltaic-thermal flat plate collector has been derived as a function of design and climatic parameters. This paper shows the detailed analysis of energy, exergy and electrical energy by varying the number of collectors by considering four weather conditions (A, B, C and D type) for five different cities (New Delhi, Bangalore, Mumbai, Srinagar and Jodhpur) of India.It is observed that the collectors fully covered by PV module combine the production of hot water in addition to electricity generation and it is beneficial in terms of exergy, thermal energy and electrical energy gain.

“…Firstly, water absorbs the sunlight mainly in the infrared region; secondly, water is fully transparent in the short-wavelength region, so that the long-wavelength irradiation can be absorbed by water to produce heat, and short-wavelength irradiation can be utilised by PV modules to produce electricity. Other researchers [54][55][56] have also confirmed such a natural compatibility of water to PV modules. Figure 4 shows the optical transmission spectrum of a water layer with a thickness of 1.5cm [54,55], as well as the absorption spectrum of a mono-crystalline layer of a PV solar cell with a thickness of 50μm [55,56].…”

Figure 4 shows that water absorption only slightly affects the working region of a silicon PV cell (water transmissivity decreases at around 950nm), but it strongly absorbs the sunlight with the wavelengths above 1100nm.…”

Thermal applications are drawing increasing attention in the solar energy research field, due to their high performance in energy storage density and energy conversion efficiency. In these applications, solar collectors and thermal energy storage systems are the two core components. This paper focuses on the latest developments and advances in solar thermal applications, providing a review of solar collectors and thermal energy storage systems. Various types of solar collectors are reviewed and discussed, including both non-concentrating collectors (low temperature applications) and concentrating collectors (high temperature applications). These are studied in terms of optical optimisation, heat loss reduction, heat recuperation enhancement and different suntracking mechanisms. Various types of thermal energy storage systems are also reviewed and discussed, including sensible heat storage, latent heat storage, chemical storage and cascaded storage. They are studied in terms of design criteria, material selection and different heat transfer enhancement technologies. Last but not least, existing and future solar power stations are overviewed.

“…In solar energy research field, heliostat has been applied mostly in the high temperature solar furnace, solar power station and stirling engine based solar concentrators. Hybrid systems for solar (renewable) energy utilization have attracted considerable attention from scientists and engineers during the last decade because of their higher efficiency and stability of performance in comparison to individual solar devices [7]. They make use of waste heat and solar energy for generation of electricity, or even for direct applications such as heating of water, refrigeration or air conditioning.…”

Abstract-this paper aims to provide a prototype design for future large scale power production to mitigate energy crisis faced by Pakistan these days. The design is based on an inexpensive dual axis heliostat mirror assembly which tracks the sun and concentrates the solar energy at point where thermoelectric generators are installed to produce electrical power. The sensor less tracking of sun and movement of the system is governed by complex astronomical calculations which give the location of the sun at a particular latitude, longitude and time. The system employs accurate gear assemblies and feedback control system to achieve precise and smooth motion required for tracking. Maintenance free software of the system needs only to be configured once. It only has one time manufacturing cost and its maintenance cost is negligible with respect to output of the system. The paper concludes with the accuracy and stability of tracking system for future development usage.
