Investigating The Solar Energy System Engineering Essay

Harmonizing to Tripadvisor, in 2010, in travel determinations, travelers expect to be more environmentally is up to 22 per centum. Furthermore, 44 per centum of travelers prefer to remain at green hotel or environmentally-aware hotels. Actually, 33 per centum of travelers booking decide hotels which have green policies. ( Varner, 2009 )

Based on current planetary warning and lifting energy costs, the demand for sustainable energy, salvaging money and environment is an pressing thing above all others. That ‘s why solar power becomes really popular option faster than of all time. Nowadays, this sustainable energy has produced so many merchandises such as solar movie, solar panel, solar pool warmer, solar cellaˆ¦ and about these merchandises are created by two types of solar panels including photovoltaic faculties which convert solar heat into energy, and solar thermal aggregators which can hive away the heat from Sun and transportation to the topographic point where needs warming. ( Solar Energy Advantages organisation, 2007 )

Solar is the best sustainable energy which meets demand energy. Compare to weave, H2O, heat and beckon energy, solar energy is more stable, available, flexible and abundant than other energy. Actually, this energy has possible than other energy in economic system ; the United States solar industry forecasts more than four 100s 40 1000s lasting, full-time occupations in 2016. In engineering, utilizing solar energy expeditiously is current tendency in the universe, so many inventions based on solar panel are created such as solar sofa tabular array, solar charged vehicle, solar lamp, solar charged and solar window, and this is an invention which is in advancement. ( Solar energy, 2010 )

This is an operation of solar panel system: sunshine is the signifier of renewable energy, and solar panels collect and convert it into electricity which can be used to back up for electrical tonss. Solar panels are composed of a great figure of single solar cells which are themselves comprised of silicone, phosphoric ( the negative charge ) and B ( the positive charge ) . Photons are absorbed by solar panel and in making so originate an electric current. That energy strikes the surface of the solar panel which allows their atomic orbits knock out negatron. At the same clip, this negatron releases into the electric field making by the solar cells which cal pull all these free elections into a directional current. Photovoltaic is a name of this full procedure.

Therefore, how many is solar panels necessary to supply plenty solar electricity to provide? All need support from an inverter which can change over the DC current ( or the direct current ) , produced by a solar panel into AC current ( the jumping current ) , solar panel arrays can be sized to fulfill all demanding electrical burden demands. ( Yedda, 2009 )

Can ordinary Windowss be turn into solar panels? This is occupation which MIT scientist is researching by the charming blend. Absorbing light while re-emit energy into the glass by a broad coloring material scope with complex systems. That energy is gathered in the window ‘s border and converted electricity. This can convey hope to a commercially-ready version in future. With this invention, skyscrapers do n’t merely fulfill the infinite of life, but besides it can supply energy for whole metropolis. Besides, we can salvage infinite for immense solar panel, and cost for install energy solar. In general, this merchandise can supply another position for developed metropoliss. ( ubergizmo, 2008 )

Among solar energy merchandises, solar window movie is more popular. Actually, its map satisfies consumer demand such as commanding up to ( 78 % ) the effects of solar energy ; barricading harmful UV rays up to ( 98 % ) ; absorbing blaze under any fortunes including direct sunshine, or sunlight reflecting from snow, H2O or environing Windowss ; supplying interior temperature balances and climate control ; minimising harm of tattered spectacless by keeping it together as a “ safety cyberspace ” ; holding uniform design which can back up the visual aspect of hotel ; maximising the salvaging cost for electricity and easy to put in in hotel. ( Euroguard, 2009 )

Other map of solar panel is to bring forth heat. Solar panel can roll up the heat in sunshine, and this system is called solar thermic aggregators. This is a particular solar panel which is made for specific absorb the sunshine to bring forth the heat. ( Pakhare, 2007 )

Today, there is tendency of using solar optical affects on the thermal of window, particularly the Windowss which used by the thermal and optical effects of solar screen stuff. Actually, the Window 4.1 plan is recommended to use the thermic computation on the window ( Finlayson et al. 1994 ) . Harmonizing to the way of John Elliot Engineering Associates, Inc. ( 1982 ) , Yellot Solar Energy Laboratory are implementing some plan which includes step of the thermic belongingss of the solar screen stuff, using the spectral database for Varicon glass merchandises on the glass optical belongingss. ( Energy nest eggs 4 you, 2002 )

An operation of solar thermic aggregator will explicate with a simple illustration below: solar panel is a closed box which has a top made of crystalline stuff by glass. When sunshine radiates through the glass, it besides heat up the interior of the box. If the interior of male child has black coloring material, so, it strengthen soaking up more heat. The thermal is collected inside the box can be used for heating air.

A solar thermal energy system to heat air is non excessively complicated. A glass top is attached to a box. There is an recess pipe in box for cool air. By utilizing a fan, the cool air can travel into the box. In the box, the cool air moves through the recess pipe. With the Sun beams and the temperature in box, cool air becomes warmer. Furthermore, if cool air continues to be pushed into the male child, the warm air has to acquire out from the box through the mercantile establishment pipe. Now, you can utilize warm air to heat your place. In world, this big system is more complicated. ( Make It Solar, 2005 )

The large weak point in solar systems is that it merely works when the Sun is reflecting or on summer. Therefore, rain season, winter, cloudy twenty-four hours and dark, solar energy is worthless, and we have to utilize natural gas to bring forth electricity or heat air. However, this undertaking does n’t intend depending on solar energy wholly, or replaces current electricity system by solar energy system. It merely shows you the benefit of bound or preservation of scarceness energy by utilizing limitless energy. Today, harmonizing to United States Census Bureau, in 22 March 2010, the universe population is up to six point eight billion peoples ( 6,809,900,000 ) . If six billion people do n’t utilize scarcity energy during one hr, so how many energy we can salvage for future, how many money we can salvage, how much pollution we can cut down? These inquiries are replies for benefit of sustainable energy, particularly solar energy and why we apply it in cordial reception industry now. ( California Energy Commission, 2002 )

Charging Table

The tabular array design ‘s mission is to soothe concern traveller. Equally long as hotels lead in this merchandise, concern travellers do n’t necessitate to convey coursers or arrangers for any of their digital devices. Since 2006 there are several states and European Union start to put a criterion for cell-phone digital coursers. The ground for this criterion is to cut down waste of courser. Harmonizing to the analysts of Global System for Mobile Communication Association ( GSM ) , there are 12 hundred million nomadic phones were sold out, 50 % ~80 % among the figure are in placement demand. It means there are about 5~8 dozenss ‘ courser does n’t necessitate to be produced ( Ms. Xiao Li Chen, 2009 ) . GSMA are looking for a manner to cut down 51 thousand dozenss of excess coursers each twelvemonth ( Jonathan Ong, 2009 ) . Harmonizing to consumer ‘s foundation, Chinese Taipei ‘s study, there are 99 % of population support that all coursers should be Unified Specification ( Ying Lan Liu,2008 ) .


In 2006, ministry of industry and information engineering of the people ‘s democracy of China publishes a regulation- Mobile Handset Charger and Interface Technology Requirements and test methods regulation. Ministry of industry information ( MII ) revises consolidative charger standard ordinance in 2010. MII has announced that authorities of China levies all nomadic French telephones should fit with a standard USB courser. The lone difference of ordinance between 2006 and 2010 is the connexion of cell-phone and courser become three-stage construction and coursers should be able to bear down different trade name theoretical accounts of cell-phone through the USB entree ( Chi Ru Chen, 2010 ) . Nokia ‘s nomadic phone coursers are produced to make China ‘s regulation- three-stage construction and besides the interface of the cell-phone is following the standards. Another two well-know nomadic phone companies- Motorola and Sony Ericsson are be aftering to alter their cell-phone interface to run into new criterions of China ( Chi Ru Chen, 2010 ) .

European Union

Harmonizing to Jonathan Ong ‘s study “ International Telecommunication Union, a subdivision of the United Nations, has eventually approved a criterion for a cosmopolitan phone courser to be used for all nomadic phones in the close hereafter. ” This legislative act will profit each of digital users that can bear down their Mobile anyplace by any sort of courser. This passage besides reduces the sum of unneeded cell-phone coursers. The GSM Association besides predicts there will be about 50 % decrease in standby energy ingestion ( Jonathan Ong ) . It will be one of the specific action which protects the environment from battery injury reflect to the bill of exchange Copenhagen Agreement toward extenuating planetary heating. From Yi Hau Yu ‘s study she says consumer protection association in Berlin petitions this regulation should n’t merely for cell-phone but besides used on all little digital devices ‘ courser including MP3, camera, and PDA ( Yi Hau, Yu ) .

Wireless Charger

A company called Powermat has introduced wireless courser to the market. This engineering has been used for single or office. “ This is the bear downing station you ever dreamed of. One cord, one mat, one topographic point to bear down all your handheld devices. ( Powermat USA ) ” This is the intent what Powermat wants its consumer experiences. Powermat ‘s new invention brings consumers an easier, more comfy, convenient life with a radio courser in manus. The wireless courser can bear down either kindles, eReaders, digital Kodak cameras, Bluetooth headsets, many mobile phone trade names and theoretical accounts. In our merchandise we are traveling to utilize this sort of engineering in cordial reception industry.

Multi Voltage Power Adapter- Chinavasion

More and more concern travellers go abroad and the demands of multi power arranger growing. This invention provide multi-voltage power arranger for immense scope of digital devices such as cell-phones, digital cameras, laptops, MP3 or MP4. Most of celebrated trade names of laptop can be used by this merchandise like Acer, Asus, IBM, HP and so on. Peoples can take voltage scope from 12 to 24 Vs for laptop or 5 Vs of power end product through the power arranger indicates. With this engineering installs in our energy tabular array people merely choose the state where they come from, what sort of digital devices they are utilizing and the trade name of their digital devices so they can get down to bear down their battery.

Hand-Touched Screen

Hand-touched screen is widely applied in nomadic phone, laptop, and PDA. Peoples are non unfamiliar utilizing hand-touched screen. One of the most well-known company utilizing hand-touched screens on its merchandise is Apple which even apply an innovation-multi touch toward its merchandises ( Apple, 2010 ) .

Solar Battery

How can people utilize electricity after the Sun sets? The solar energy can be stored in the solar battery. This engineering is used on solar warmer or single. Many people already acknowledge the importance of utilizing rechargeable batteries instead than disposable 1s ( solar place, 2009 ) .
