Factors In Choosing Home Solar Power Panels

What Are Home Solar Power Panels?

 The main function of a solar panel is to transform sunlight rays into usable electricity, by using the photovoltaic cells. Solar panels consist of solar cells that are integrated within a frame. The solar cells can convert the sunlight into useful electricity, individually. However, the conversion rate of every single cell is somewhat limited in terms of total wattage output, where each of the cells can only produce electric power equivalent to 1 to 2 Watts. This necessitates the integration of a larger number of solar cells into one solar panel that can also be interconnected to each other to form a solar panel array. This is a necessary technique to a sufficient amount of solar power that can be used in homes. 

The capability to integrate solar cells so that they can produce a higher volume of power is the advantage of the solar cell system. This implies that if you may require more power for personal consumption, you only require additional panels.

We have different types of solar power panels in the Polysilicon Solar Market that have different power generating capabilities and features, which is dependent on the material used for manufacturing. These materials include thin-film, mono-crystalline, or polycrystalline modules. The Thin-film solar cell is usually made of alloys (normally amorphous-silicon) that are stored in thin layers, which are deposited on a substrate. This makes it quite supple (depending on the substrate used) and flexible for application in certain environments.

However, Mono-crystalline, which is created from one silicon crystal rod, is considered to be having a rigid structure. The silicon rod is usually cut into thin wafers, which provides the base within which solar cells can be formed.

On the other hand, Polycrystalline solar cells are processed from numerous silicon crystals that are heated together. After this, they are cooled into molds that form ingots of silicon. After which the ingot is cut into wafers, which are processed as before to produce solar cells.

The Ratio of output and input power can be used to measure the efficiency of a home solar power panel. Generally, solar panels have an efficiency that ranges between approximately 10 percent to about 19 percent.  Normally, the cost of the panel is likely to be higher about a higher efficiency rating. It is prudent therefore that when you plan to do a new installation’ you should take into consideration the initial installation costs against the benefits of savings from efficiency in the long-term.

You will need insight on some specific Polysilicon Solar Market parameters to be able to determine the right solar panels for your application. The three important measurements are, 'efficiency,' 'rated power at STC,' and 'rated power per square foot.'

  • 'Efficiency' refers to the ratio of the output power from the solar panel to the input power of the sunlight reaching it.
  • 'Rated power at STC' refers to the total output in watts from the panel under Standard Test Conditions.
  • 'Rated power per square foot' is the power output of the solar panel at Standard Test Conditions per square foot of the panel's surface area.
  • Modern home solar power panel is designed to maximize the generation of electricity from solar energy.
