I need some assistance with these assignment. design procedure of solar systems for green buildings Thank you in advance for the help! The procedure for the design and construction of solar panels for building takes mainly a three-step procedure. These include the selection of raw material, manufacturing, and lastly quality control (Gevorkian, 99).
Design and manufacture of solar panels apply the use of the quartz or quartzite grave, carbon elements, phosphorus, boron, titanium dioxide, and copper for different purposes at different stages in the production of the products. The elementary or the base material entailed in the design and construction of solar panels is silicon. The silicon is usually not pure. The selection of the appropriate silicon dioxide is undertaken from quartz or quartzite gravels (Krebs & Frederik, 97).
The manufacturing outline/process begins with the purification of silicon. Collected quartzite gravel or even quartz material is normally put in position in an electric arc furnace for the heating and separation of oxygen elements in it through the application of carbon arc. The generated compound is normally silicon with high levels of purity having close to one percent impurity levels. The purity level is important in other industries but in the solar panels manufacturing industry. Further purification is undertaken through the application of the floating zone technique in which a rod of impure silicon is continuously passed through a well-heated sector several times in one direction. The procedure normally drags the final impurities towards the end with every passing. The silicon collected in the end is labeled as impure, and it is hence removed while the rest is scooped off (Magee, 68).
The next stage is called the Czochralski method. In this method, a seed crystal portion of silicon is normally plunged and dipped into melted polycrystalline silicon. The seed crystal is finally withdrawn then rotated to create a cylindrical ingot. This structure is mostly referred to as a boule of silicon. This withdrawn ingot has a very high level of purity since most of the impurity remains in the liquid. After the formation of the boule, the next stage is the formation of the silicon wafers. This process is mostly done through the use of the circular saw whose inner diameter aids in cutting of the rod.
