Heating of water for domestic purpose by making use of solar energy is essential and it is one of the effective ways of utilizing solar energy. Initial cost of solar water heating (SWH) system is high, but the operation cost is zero. This paper discusses on improving the performance of a flat plate solar energy collector by changing the design parameters of the number of riser tubes and the arrangement of riser tubes in zig-zag pattern from the existing flat plate collector system (FPC) and using the different working nanoparticles with base fluids like aluminium oxide mixed with water. Experiments were conducted using copper tube in headers and risers with two different configurations and maintain the same dimensions. The performance comparison was made for all the two types of collectors in closed loop. The performance shows that the efficiency of FPC with zig-zag arrangement of tubes (Z-Configuration) is higher than that of conventional FPC. Thus the newly presented FPCs system produces higher efficiency than the existing conventional flat plate collector system.

Domestic Purpose

India has a huge potential of solar energy as it is gifted with 300 sunny days in most part of the country. The simplest form of harvesting solar energy is to use it for water heating. Most of the solar heating systems developed before were big in size, uses more space, difficult to install and use it for domestic purpose. To make the installation of solar heating systems simple and compact with adequate improvement in performance, a novel sun point collector has been developed. In this paper reduced land use of solar water heating systems by using sun point collector is analysed. A new comparative test on two different types of conventional solar flat plate collector (FPC) and sun point collector (SPC) was also investigated by conducting experiments. A standard glazed flat plate collector and a novel sun point collector are installed in parallel and tested at same working conditions. Results are also presented in terms of daily efficiency versus daily average reduced temperature difference: this allows representing the comparative characteristics of the two collectors when operating under same conditions.

The present study deals with comparison of experimentally determined performance characteristics of solar flat plate collectors fitted with novel designs of absorber plate involving non-circular risers with integral fins and operating under natural circulation mode. The main flow passages considered were square, triangular and semicircular in cross section. One standard solar flat plate collector with circular risers was also tested simultaneously for direct comparison. The test results indicate that the absorber fitted with the triangular sectioned risers yields the best performance in terms of the efficiency (63%), and the buoyancy induced flow per unit area (76 kg/hr-m2) from amongst the collectors investigated. It is followed by the absorbers fitted with the semicircular and square sectioned risers respectively. The standard solar flat plate collector is found to yield the lowest values i.e. 46 % and 40 kg/hr-m2 respectively.

Flat Plate Collector

Solar energy collectors are a special kind of heat exchangers that transform solar radiation energy to internal energy of the transport medium. The major component of any solar system is the solar collector. This is a device which absorbs the incoming solar radiation, converts it into heat, and transfers this heat to a fluid (usually air, water, or oil) flowing through the collector. The measurement of the flat plate collector performance is the collector efficiency. The collector efficiency is the ratio of the useful energy gain to the incident solar energy over a particular period of time. The useful energy gain is strongly depends on the collector efficiency factor and this factor directly influenced by few parameters i.e. the centre to centre distance of absorber tubes W , thickness of absorber plate δ and heat loss coefficient UL. This paper has been focused on the relation between W with collector efficiency factor of serpentine tube solar flat-plate collector. This study shows that if we increase the W then Fˈ decreases.

A solar radiation model to determine solar energy collection on solar collector array with different aspect ratios has been developed. The relations between the aspect ratio and the average daily solar radiation collection on the collector array have been deeply studied. The results show that there is an optimum aspect ratio to maximize the solar energy collection on the collector arrays. The optimum aspect ratios of the 1000 m2 collector array for Haikou, Kunming, Lhasa and Beijing are 10/1, 1/3, 5/1 and 10/1.The optimum aspect ratios of 1000 m2, 500 m2, 200 m2 and 100 m2 collector arrays for Kunming are 1/3, 3/1, 7/1 and 1/5, respectively.

Flat Plate Collector

Solar energy is radiant light as a form of thermal heat energy which can be obtained and used by means of a variety of solar apparatus. As apparatus the flat and curved plate solar collector is specifically designed for assembling solar energy as a solar water heater system. The designing potency of this collector lone can generate medium level hot water from radiant sunlight source via absorbed plates. Standard type flat and curved plates solar collector plates are mostly used in remote coldest regions of the world where hot water is consumed for commercial and domestic purposes. These types of solar collector Plates can cheaply be manufactured compared to other solar panels like solar Shingles, Polycrystalline Solar Panels, Mono-crystalline Solar Panels, and Thin Film Solar Panels. For future work, this proposed pre-design is recommended for fabrication. A numerical study was carried-out on eight city locations in China by tracing their horizontal and vertical longitudinal, latitudinal lines noting the date, time and sunlight feeding of temperatures in the Celsius scale with the help of simulation and modeling tools like CFD, ANSYS FLUENT software, mesh geometry tools, and by using the Navier-Stokes and Continuity equations by fluid flow discharge rate, mass flow, water temperature and dropping of temperature, radiation working mechanisms, dimensions of water flowing tubes and absorber plates, density, the velocity of water as the working fluid, the viscosity of water in a cold and hot state as a process of Pre-design. Work also focuses on the comparison between flat plate collector and curved plate collector radiant sunlight absorption, As end result it is found the Curved plate collector produces 22% more elevated heat of outgoing water than flat plate collector.
