The main parts of the flat plate collector (solar geyser) are the glazing, pipes, heat collecting absorber flat and insulating body. In this research an effective flat plate collector has been fabricated for solar geyser, which is low cost, simple design, and easier installation for heating purposes. More focus has been given to the heating loss and collecting solar radiations. Controlling the heat loss, the fluid can absorb more thermal energy which increases the efficiency. A different technique has been employed to enhance the efficiency of solar geysers. Effect of using double glazing to control the heat losses, because the temperature between glass covers and the absorber is not equal to environment. Increasing the length and reducing the diameter of the pipe improved the heat harvesting and observes more heat from absorber sheet. Keywords Solar collector Flat plate collector Cost 1. INTRODUCTION The burning of fossil fuels increase air pollution, the level of CO2 has increased more than 30%, and surface temperature increased about 0.8 o C, causing climate change [1-2]. On the other side much energy is required to industries due to increase in population. The renewable energy concept can solve this problem. It is the energy obtain from natural processes which refilled constantly. The energy is collected from renewable resources are naturally refilled by wind, rain, tides, sunlight (sun irradiation) and geo heat. This energy cannot be collected without proper systems such as wind turbine, photovoltaic (PV) panel and solar thermal collector, which may provide the best way to get energy without air pollution, low cost and with high yield [3].
