Solar Panel 2

Sunlight absorption rate as high as 96% of the solar panels come out

According to foreign media reports that the U.S. research team has recently developed a new solar panel, the board covered with a layer of cells can absorb all the angles and absorb sunlight as high as 96.21 percent of the solar panels coating materials.

The Study Group said the solar panels can absorb ultraviolet rays, visible light and infrared wavelengths, and so all the sunlight, but also to absorb the sun's point of view of all, even in the absence of the sun tracking device can maintain a high absorption rate.

Brief history of solar panels

solar cells have become cheaper and more efficient in recent years, as researchers have looked to them as an alternative energy source. Solar panels are used in satelites. They can be use in conjunction with rechargeable batteries, such as the lead-acid or nickel-cadmium types, to provide power independent of the commercial utilities.

The first solar panel-powered satellite was launched in 1958 by Hoffman Electronics, and until the late 1970s solar panels were used primarily to power space satellites, lights, and small electronics like calculators and watches. In the early 1990s Germany and Japan initiated long-term solar panel-installation incentive programs that resulted in lower costs for solar panel power and spurred the growth of robust PV industries in both countries.

How much power do solar panels produce?

Solar PanelIn direct sunlight at the surface of the equator, a maximally efficient photovoltaic cell about 1/5m in diameter creates a current of approximately 2 amps @2 volts, however, due to the Earth's atmospheric interference, terran solar panels will never perform as well as solar panels exposed directly to the sun's rays.
Years of overheating and physical wear can, however, reduce the operation efficiency of the photovoltaic unit. Solar cells become less efficient over time, and excess energy is released into its thermally conductive substrate as infrared heat.
The amount of power solar panels produce is influenced by the quality of the solar panel, the materials and technology used in making the solar panel, and the amount of time the solar panel has been in use. When purchasing solar panels, it is therefore wise to look beyond size and look at the dollars/watt ratio.
You don’t need to know the detailed physics of solar electricity to understand its appeal. However, it’s wise to be familiar with some solar panels components and terms.

The Components: Photovoltaic cells are the core of the solar panel. They are made up of at least two layers of semiconductor material (usually pure silicon infused with boron and phosphorous). One layer has a positive charge, the other a negative charge. When sunlight strikes the solar panel, photons from the light are absorbed by the semiconductor atoms, which then release electrons. The electrons, freed from the negative layer of semiconductor, flow to the positive layer.....thereby producing an electrical current.Since the electric current flows in one direction (like a battery), the electricity generated is called direct current (DC). Many individual cells are wired together in a sealed weatherproof unit called a solar module or panel.

Terms to know before you shop for a solar electric system:

Net Metering: A service option available from your electric utility that allows your electric meter to spin backwards when excess energy is generated by your solar electric system. The excess energy is effectively stored by the utility until it is required for future use by the customer.

Inverter: A device that converts Direct Current (DC) into Alternating Current (AC).

Solar Cell: The basic building block of a solar electric system. Solar cells are made of a semiconductor material and convert sunlight directly into electricity.

Polycrystalline Silicon Panels

Solar Module: A group of solar cells, modules are the smallest solar electric components sold commercially, ranging in power output from 10 watts to 300 watts.

solar panel:a panel exposed to radiation from the sun, used to heat water or, when mounted with solar cells, to produce electricity direct, esp for powering instruments in satellites

All in all,the solar cell is one small (approx. 4"x4") area on the surface of a solar module. The module is made up of many solar cells set into a frame for support. A solar panel is several solar modules installed together on a rack. Put some racks together and you have a solar array.
