The basic human needs are fo?d water?nd clothing; however?n ou? modern s?ciety w??ay as well add one,?lectricity. Society in mo?t culture will not funct?on if w? wer??ut?f electricit?. Since t?e inception of?ts use?n the late 19th century, electricit??as becom? t?e most widely used energy sourc? and has led to t?e impr?vement and d?ily usage of modern convenienc?s; fr?m light-bulbs to refrigerators, stov?s, irons and wash?ng machines and more high tec? devices s?ch a? comp?ters, ster?os?nd even s?me ca?s now.

Wit? us extensively?sing?nd exploiting f?ssil f?els?e are c?using? lot of har? to the environment. Our "gargantuest" de?and for ene?gy is the ca?se of green?ouse gases effect, depletion?f natural?esources, and causing hazardous wor? c?nditions fo? s?me of us (those?ining t?e c?al and stationed on oil rigs). Further more it?as also led to t?e?hanges of?ur climate wh?ch i? gener?lly referred to as "the climate?hange." However the?e?s ho?e, these changes can be reversed and these?dverse?ffects?an b? only historic fa?ts. In the l?ght of th?se particul?rs?lternative energ? resources such as?olar panels are viewed?s a solution. Integration of solar po?er technology in?ouses and b?ildings?s getting so?e prominence especially in Europe. A? demand for t?is t?pe of clean and?enewable energy i? increasing, research?nd developm?nt in this sector has bro?ght some great impro?ements to solar panel production; how?ver the upfront c?sts assoc?ated with th? proc?rement?nd installation?f t?ese dev?ces ar? still significant.

T?e cost of? sola? p?nels syst?m and?ts resulting power?utput depends?pon?ts us?, the?aterials it's?ade?f, and its overall qu?lity. The?e factor??ill furthermore determines t?e life span of the o?erall System. A?olar?rrays of 55 watts h?s?n?verage c?st about $98.00, wh?ch is about $1.55 per Watt. T?is i? usually bulk price and does not include installation. A small-scale?ff g?id of 500 Watts f?r? h?me professionally installed co?t around $3,455.00 t?at is $6.91 per Watt. This pric? is the complete system, equipment?lus labor. The p?ice for a medium-scale off grid installation w?ich would be ab?ut 810 t? 1400 Watt? c?st abo?t $6.79 pe? Watt wh?le a large-scale off grid hous? installation?f 2688 to 4032 Watts would be average $5.48?er Watt. T?is?ay s?am? bit ex?ensive?ut conside? that the c?st of a solar s?stem is easil? rec?vered d?wn t?e road a? th?re wo?ld be no ele?tric bill fo? t?e life of th? system th?t i? for the next 20 to 25 ye?rs down the road. Albeit?n occasional maintenance cost.

The?bove comparison cl?arly illustrate th?t t?e b?ggest expense?ssociated to such s?stem?s the installation f?e. The relatively hig??rice of professional installation?s mainl? due to t?e fe? qualified skilled technicians?s solar energy i? an eme?ging technol?gy. With these?n mind it is?lso advisable to f?lly benefit from such installation, energy efficient applianc?s sho?ld b? used. This?ill e?tend the lifet?me and effic?ency of the solar system.

A solar panels system is?ery delicate and sens?tive to dust and oth?r parti?le pollution that may obstr?ct t?e cells as su?h proper ma?ntenance should be?onsidered. However, newer m?dels are manufactured o?t of less tensile and pollut?on proof materials, thi? way strengthening them, increasing the?r resilience?nd functionality. T? optimize the us? of s?lar panels, p?oper orientation to the s?n i??aramount and the geographical location?ill also aff?ct its performance. The best?ay of overcoming these hurdle?nd g?t the best value for your mon?y is to pick a trustworthy?olar powe??nstaller or technician.

As mention earlier once installed?nd excluding the cost of maintenance, the c?st?f electricity generated b? sol?r a?rays i? relativel??ero. On the other hand using fossil fuel in power pl?nts the?e i?? permanent need for fu?l?s long a? el?ctricity i? gen?rated and "that fuel" needs t??e purchased. With solar panel techn?logy, a? long as the sun?eeps hitting this planet, one can gener?te?ll the elect?ical energy t?at?s needed.

At fir?t glance it m?y appe?r e?pensive to u?e solar power how?ver, there are m?re?enefits th?n disadvantages. Compared to the small but cum?lative operating c?st wh?n u?ing fossil fuel? ba?e electricity, th? savings w?th s?lar panels utt?rly surpas? the other. Sola? energy i? safer, cleaner and eco-friendly. As governments starts conside?ing these benefits and dem?nd fr?m ecological?onsumers incre?ses, t?e trend of solar powe? utilization will eventu?lly decrea?e th??nitial cost of solar po?er. Everything on our planet, Earth,?s linked, and truly E?rth?s linked t? the sun, its original?nd fo?emost energy sour?e.
