Parabolic solar collector water heating system

In this paper design solar collector for water heating presented.Conditions of world forcing humanity to find new sources for energy .Other natural sources are limited in the world therefore we choose sun as a unlimited source.A solar collector is tranforms solar lights from sun into energy and transferred to fluid in the pipes.we try to design and develop solar collector will be high efficiency , less surface area , more energy produce and minimize the cost.

            There are some types of solar collector that use for this kind of projects.Capture the sun’s solar radiation to a surface of solar collector and focus it into a small point area,increasing solar energy in the same time decreasing the surface area of collector is our purpose .There are a lot of types of  applications,These are solar water heating , integrated collector storage,industrial process heat,thermal power systems.As seen solar systems can be used in huge sector and has a lot of benefits.it should be used for all applications when is possible.
