Factors in Choosing Home Solar Power Panels


What are the solar panels of the house? The main function of a solar panel is to convert sunlight into usable electricity. This effect is a physical manifestation of the photovoltaic effect. Solar panels are composed of solar cells which are collected in a frame. Each solar cell has the ability to convert sunlight into useful electricity. However, the conversion rate of each cell is somewhat limited when measured to the total power output. Basically, each cell produces electricity quantity corresponding to 1 to 2 watts. Therefore, a very large number of solar cells must be embedded in each solar panel, and usually a large number of panels are connected to form what is called a solar panel array. This is necessary to produce a useful amount of solar energy for a full house.

This set of solar cells collectively to establish a higher power is an inherent advantage of the solar cell system. This means that when more power for personal consumption is needed, simply add more panels.

There are several types of solar panels, which have different characteristics pub features energy depending on the material they are made. They may consist of modules polycrystalline or monocrystalline thin layer. The thin film solar cell comprises silicon alloys (amorphous) stored in thin layers deposited on a substrate. This means you can be very flexible (depending on the substrate used) and is therefore more easily applicable in some environments by.

Monocrystalline, on the other hand, is created from a silicon crystal rod and can be considered to have a rigid structure. The silicon rod is cut into thin slices to provide the base within which solar cells are formed. Polycrystalline solar cells are processed in many silicon crystals are heated together, then it cooled in molds to form silicon ingots. The ingot is then sliced ​​and treated as above to produce solar cells.

The efficiency of a solar panel house is measured by the ratio of output and input. Usually, solar panels return a yield ranging from about 10 percent to about 19 percent. As expected, the higher the rate of efficiency gains, plus the cost of each panel will also be higher. When planning a new installation, it is necessary to take into account the costs of initial installation with a better long-term efficiency to make the right decision for you.

Determine appropriate solar panels therefore it requires knowledge of certain specific parameters. These settings will help you decide which solar panel for use in your application. Three important steps to consider include “efficiency”, “nominal power at STC,” and “nominal power per square foot.” Efficiency “is the ratio of the power output of the solar panel to the input power of light Sun reach. ‘classified STC Energy’ measures total output in watts of the commission under standard test. “Rated power per square foot” is the power output of the solar panel in standard test conditions per square foot of the panel surface.

Finally, modern house designed solar panels to maximize power production from solar energy and are now a very viable option to use this form of “renewable” energy consumption to meet the staff house.
