Laser Distance to Take a Better Measurement

Measurement of a building, field or outdoor, or measurement of the distance between one building with another standard building can be done manually by measuring using a meter. The trick is to spread the meter on the place to be measured area or distance. This step is very simple to do, but sometimes because of human negligence measurements using a meter in this way can cause a mistake. Not exactly in seeing the measurement results of the meter is one of the common mistakes.

Measuring using this meter is also considered a bit troublesome if a building or land to be calculated area is too large so it takes at least two people to make measurements. This is very impractical, not to mention if the error of seeing the number on the meter again occurs. Inaccurate measurement at the beginning will cause errors in the next step. Then, how is the solution to minimize errors during the measurement? One way that can be done is to measure it using a digital laser meter or laser distance.

Not many lay people are familiar with the tool which is called as the laser distance. So, for those of you who are also hearing about this tool for the first time, you can know the tool in more details on the website that you can visit on The digital laser distance meter is only familiar in the ears of those who are engaged in the construction world. As the name implies, this tool can also be used to measure distances very effectively using lasers. This tool is certainly very easy and helps someone in making measurements. The measurement which is taken by using a digital laser distance meter will also be able to be accurate and free from errors that may occur when a person performs measurements using a regular meter manually.

Type of Solar Cell

Until now there are several types of solar cells that successfully developed by researchers to get solar cell devices that have high efficiency or to get a cheap and easy solar cell device in the making. Solar cells are used for off grid solar system.

The first type successfully developed is a single crystalline silicon (laminated) type of wafer. This type of its development is able to produce a very high efficiency. The biggest problem faced in the development of single crystal silicon for commercially produced is the extremely high price making the resulting solar cell panels inefficient as an alternative energy source.

The second type of solar cell is a poly crystalline silicon wafer type. Currently, almost most of the solar cell panels circulating in the commercial market come from the screen printing of this type of poly crystalline silicon. Crystal crystalline silicon wafers are made by making a thin layer of silicone rod by the wire-sawing method. Has each layer a thickness of about 250- 50 micrometres.

This type of solar cell has a cheaper manufacturing price although its efficiency level is lower when compared with single crystal silicon. Companies that actively produce this type of solar cell is GT Solar, BP, Sharp, and Kyocera Solar.

Both types of silicon wafer above are known as the first generation of solar cells that have a thickness in the range of 180 to 240 micro meters. Earlier research and has long been done by researchers to make silicon-based solar cells has become a growing technology and is dominated by researchers and industry. This solar cell device in its development has been able to reach 25 years of active age.

The second generation of solar cells is thin film solar cells (thin film). The idea of making thin-film solar cells is to reduce the cost of making solar cells since this type uses only less than 1% of the silicon feedstock when compared to raw materials for wafer type silicon. With such a high savings in the raw material, it makes the price per kWh of energy raised to be cheaper.
