hoh
nih topic faveret aku

actually the most advance solar cell nye efficiency pon skarang nih 3+% je...
that's mean it can harvest 1/3 sun's energy
and yg tuh guna material yg mahal gila aaa. ...

i'm doing study on sustainable energy as well...huhu....technical giler.....

solar energy sesuai digunakan ditempat yg susah dicapai oleh grid elektrik nasional. What i heard was solar panels were erected by TNB to supply electric for Orang Asli in Grik. aku tak tau kesohihan berita ni tapi sumber yg didapati boleh dipercayai.

anyway, principally solar energy will be collected by solar panel that is exposed to the sun. this will generate into DC circuit from the panel to the converter that will convert into AC current and will store the energy in the allocated storage.

yes, it is still expensive in malaysia but i believe in a few years, if the penetration of market is better then we can have it just like 'of-the-shelves'  things eh?

rasanya certain tempat kat mesia, lampu jalan pon pakai solar cell kan?
actually, malaysia the perfect place untuk pakai solar cell
sebab solar energy collection paling tinggi dekat khatulistiwa (peak dekat latitude 0)
so even if we use regular silicone solar cell yg 15% eff tuh dah cukup

even shell pon skang invest in solar cell...CIGS cell
antara top player dalam solar cell industry
ye laaa
petroleum dunia bakal abis in 30 yrs

kita nuclear plant pon takdak...padahal nuclear plant laaa energy generator paling bersih...waste product dia water je..
dam ada laa beberapa bijik...tak cukup utk generate for the whole country
solar grid takyah cerita laa

kat mana ek tempat2 keje yang nak amik org yang tau pasai tenaga solar nih...aku dulu jenuh mencarik....

tenaga nuclear mmg bersih...but risk tinggi....tkot jdk cam chernobyl....but skang pling latest...nuclear fusion...slamat n clean....exact cam matahari...good thing is..x require uranium...huhu....kalo jdk investor kene pikir byk kali...nk invest kat mane....

tenaga solar leh disimpan....ade konfigurasi susunan bateri utk maximum kan penggunaan electrik..cam selari @ sesiri...problem nye skang ni x der material yg high efficiency utk absorb tng solar....org berpendapat kos mahal....but kalo calculate blik...bese abis installment dlm 8-10thun...lpastu pki letrik free aa.....

kat amerika kalo x silap...byk kompeni bli rig(plantar minyak) yg x leh digunakan...untk psg kincir angin kat tgh laut...angin sentiasa ade la...prob..maintenance sush skit...

aku rase panel dia besar sangat la. tak buleh ke buat macam technology filtration skarang nih yg berjaya meningkatkan luas permukaan walaupun bekasnye makin lame makin dikecikkan

sedangkan incinerator pun orang tak brani pakai lagi kat sini. ala2 primitif lagi persepsi rakyat mesia nih

haha...tau xper....kalo aku la jdik pm, aku wat dsr renaissance malaya...aku agihkan budget utk bkk geran kajian/inovasi...kajian yg bgus la cam kete letrik ker,enjin tesla ker,ram jet....kalo yg kurang penting cam penyidai baju automatik x yah la...dh berjaya wat research bg la inventor tu monopoli research die dlm 5-6 thun ker...ok la gak tu at least ade technology sendiri....

Q-cell Malaysia Sdn Bhd kot yg pki org tau psl solar ni....

ok thanks............

latest info...solar cell leh absorb 500 times more than current cell
