Purpose In the present era where energy demands growing rapidly the solar module is one of the solutions and a good one. “More energy from the sunlight strikes the Earth in one hour (4.3 × 1020 J) than all the energy consumed on the planet in a year (4.1 × 1020 J)” therefore solar energy has a bright future ahead. The first solar cell was invented in 1953 and had efficacy rate of 4 present while toady’s solar cell is 40 present efficient. SolarCity is using the one of the efficient solar panels which yields 30 to 40 percent more energy than similar size solar module available in the market. Components There are many components those makes a solar panel. These components can be defined as external and internal components. A basic unit of the solar module is a solar cell and many solar cells create one solar module and more than one solar module creates an array. External Components External components are components which are used in the solar module’s external body as mention in the figure below in layers. Frame Framing play a very important role in a solar module because it will hold the panels together in addition, it protect the solar module from many environmental factors for instance wind and rain. Aluminum is commonly used in the solar module framing because of its unique properties. • Aluminum can be recycle • Aluminum is light in weight and yet gives the similar strength as steel against the wind and other environmental factors, therefore aluminum frame make
