Controlled Environment

An alternative to conventional power is the act of harnessing power from the sun using special equipment. This equipment offers varying degrees of solar panel efficiency depending on the types of materials used during construction. Existing models offer a rating of 6 percent to 13 percent and newer designs are offering a 20.4 percent rating.

The materials required to build the crystalline unit cause this model to cost more to manufacture. The different types of silicon that manufacturers use gives the unit a higher rating versus a thin film model. Ribbon silicon, mono-crystalline silicon and poly silicon are the most common designs sold in the world today.

Of the three models built, the mono-crystalline design offers the highest efficient ratings, however the fact that it is very expensive to manufacture makes it the least popular. The silicon is heated up and molded into a cylindrical shape. The silicon pieces shape does not completely cover the desired area and leaves gaps to in the four corners and due to extra costs the gaps are rarely filled.

Arguably the most popular of all silicon designs is the polycrystalline model. This model makes use of silicon that is heated up and formed into cube form and left to solidify. Once the material has set up it is extracted and applied to the conductive materials that are used during manufacturing.

Another silicon model is the ribbon silicon model, this design uses molten silicon to create ribbon formed pieces that are then attached to the conductive frame. Since the procedure utilizes molten silicon instead of hardened varieties, the process creates less waste than other designs. It is also quite popular since the cost is lower to manufacture, the companies who make them can offer consumers better prices.

Thin film designs are both less expensive and less efficient than crystalline silicon models. The reason for the lessened cost for manufacturing lies in the fact these models do not require crystalline materials to produce. Even though they are less efficient overall they are still a very popular design which is sold across the world.

With advancements in the area of solar panel efficiency, new models are being produced which offer an outstanding 20.4 percent rating. This is quite a boost from thin film models that offer 6 percent and crystalline models that offer 11-13 percent ratings. With the higher ratings comes higher costs and the new models are not yet available to the public for purchase, this is due to the cost of manufacturing.
