Ki jan Solè ki mache ak pil do travay?

solè sak lekòlMond lan deplase trè byen vit jou sa yo, e kòm yon rezilta, moun nan modèn se toujou ap sou ale la soti nan yon sèl kote nan yon lòt. te avènement de telefòn nan selil, ordinateur ak pèsonèl dijital asistan nan (PDA) fè nou menm plis mobil. Teknoloji te avanse tèlman bagay ke moun kapab kounye a pran travay yo ak yo, Unchained soti nan kabin yo. Plis ak plis zòn piblik yo branche nan World Wide Web la atravè san fil entènèt, sa ki pèmèt moun yo konekte nan pak, boutik kafe ak plaza. Ou pa ka mache 10 pye (3 mèt) nan yon vil gwo jou sa yo san yo pa wè yon moun fèmen yon kontra sou yon telefòn selilè, pou entènèt la ak yon PDA oswa tcheke e-mail sou yon laptop. Gen nan pa gen dout ke li nan yon mond dijital ak pòtab nou ap viv nan.

Pwoblèm nan ak sa a kalite teknoloji se ke li tout mande pou ji fè li rive. Kòm avanse tankou sa yo aparèy pòtatif yo, chak PDA, telefòn selilè ak MP3 jwè sou Latè sa sèlman pa lavi batri li yo. Òdinatè a pòch ki pi avanse ou te kapab imajine vin pa gen anyen plis pase yon paprvayt yon fwa batri a kouri soti.

Men, pran kouraj, teknolojik-nonm -Pa nan yon solisyon. Gen kèk moun ki entelijan te marye teknoloji selil solè ak alamòd nan fin vye granmoun- sak lekòl yo kreye yon estasyon chaje ou ka pran ansanm ak ou. tout sa ou bezwen se yon solèy ti kras ak tan, epi ou pa janm pral kout sou lavi batri ankò. solè ki mache ak pil sakado yo gadjèt yo vwayaj dènye nan mond lan teknoloji asire w ke ou rete konekte.

Eseye figi konnen kouman yon solè ki mache ak pil sak lekòl travay, nou bezwen konprann yon ti kras sou mekanik yo nan solè ki mache ak pil nan sak lekòl, Oswa teknoloji solè. Li pouvwa sanble konplike, men li vrèman trè senp - fotovoltaik (PV) selil yo se sa ki fè li tout rive. Selil yo, gwoupe ansanm kòm modil oswa panno, kolekte limyè ki soti nan solèy la ak konvèti li nan elektrisite kapab itilize. Yo ap kapab fè sa avèk èd nan yon bagay yo rele yon semi-conducteurs. Sa yo se sibstans ki ka fè elektrisite. Nan ka a nan solè selil wouj, silikon se semi-conducteurs la nan chwa.

­When sunlight hits a solar panel, the silicon semiconductor absorbs a portion of the light and its energy. When this happens, electrons in the silicon are knocked loose and they begin to flow freely. Electric fields in the photovoltaic cells wrangle those electrons and force them to flow in one direction like a cattle rancher guiding his heard. This creates an electric current that can be harnessed by attaching metal contact points at the top and bottom of the PV cell. Once the energy is collected, it can be used immediately as electricity or stored in a battery or series of batteries for later use.

The silicon semiconductor is naturally shiny and reflective, which isn’t great for drawing in sunlight. To solve this issue, an antireflective coating is applied to the cell to keep energy loss at an acceptable five percent or less. Add a protective covering to the panel and you have an energy-harnessing machine. This is enough to get you a basic understanding of how this solar technology works. Now, let’s learn more about how solar-powered backpacks puts this technology to work.

If we have solar technology and we know that the modern human is wired and always on the go, it seems like a no-brainer to bring the power of the sun with you. Some clever sak lekòl manufacturers have done just that. Solar-powered backpacks have small solar panels attached to the outside of the pack so you can harness the sun’s rays to charge your cell phone, PDA or MP3 player. The panels are lightweight, waterproof and can produce up to four watts of power. This means that just one hour of direct sunlight can produce enough energy to power a cell phone for about an hour and a half.

The key to the solè sak lekòl is the fact that it has a lithium-ion battery pack inside to store this energy. One hour of sunlight might charge your phone for a short time, but a full 10-hour charge provides up to 55 hours of stored energy. For those cloudy days, the packs also have an AC adapter that allows you to charge the battery using your car’s power. The packs come with a variety of cell phone adapters and a USB plug for your MP3 player.
