1. Photovoltaic Technology Overview

Lisele tsa photovoltaic (PV) li fetola khanya ea letsatsi ka ho toba motlakase ka phello ea photovoltaic. Sele e tloaelehileng ea PV e entsoe ka lisebelisoa tsa semiconductor, tse kang silicon, tse monyang photon le li-electrone tse lokollang, tse ntan'o nkoa e le motlakase. Ho theosa le lilemo, mefuta e mengata ea theknoloji ea PV e hlahile, ho kenyelletsa:

• Lisele tsa Silicon tsa Monocrystalline: E tsebahala ka katleho e phahameng le tlhahiso ea matla.
• Lisele tsa Silicon tsa Polycrystalline: Ho theko e tlaase ho e hlahisa empa e sa sebetse hantle hanyane.
• Thin-Film Photovoltaics: E tenyetseha ebile e bobebe, leha e na le ts'ebetso e tlase.
• Lisele tsa Solar tsa Perovskite: Theknoloji e ncha e nang le ts'episo e kholo ea ho boloka litšenyehelo le ho sebetsa hantle.

E 'ngoe le e' ngoe ea litheknoloji tsena tsa PV e na le litšobotsi tse fapaneng tsa 'mele le tsa motlakase, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse fapaneng, ho kenyelletsa le tlhahiso ea matla e nyane le e kholo. Leha ho le joalo, ha litsamaiso tsa photovoltaic li ntse li kopantsoe haholoanyane le lisebelisoa tsa elektronike, karolo ea PCB e fetoha bohareng ba ho tsamaisoa ha bona ka katleho.

Bakeng sa litsamaiso tsa photovoltaic, karolo ea PCB e bohlokoa ho nolofalletsa taolo ea matla, ts'ebetso ea matšoao le taolo ea sistimi.

2.1 Motlakase oa Motlakase le Li-Inverters tsa PV

E 'ngoe ea mesebetsi ea bohlokoa ka ho fetisisa ea PCB tsamaisong ea PV ke ho laola phetoho ea matla a DC a hlahisoang ke lisele tsa photovoltaic hore e be matla a ka sebelisoang a AC. Sena se finyelloa ka ho sebelisa lisebelisoa tsa motlakase tsa motlakase, haholo-holo li-inverters, tse fetolelang motlakase o tobileng (DC) ho tloha ho liphanele tsa PV ho ea ho alternating current (AC) e ka sebelisoang ke lisebelisoa tsa ntlo kapa tsa feptjoa ka marang-rang. Inverter hangata e na le:

• Li-transistors tsa motlakase (mohlala, MOSFET kapa IGBTs): Bakeng sa ho fetola maqhubu.
• Laola lipotoloho: Bakeng sa ho laola tlhahiso ea maqhubu a inverter le ho netefatsa ts'ebetso e nepahetseng.

Ho kopanngoa ha likarolo tsena ho PCB ea ts'ebetso e phahameng ho netefatsa ts'ebetso e ts'eptjoang le ho ntlafatsa katleho ea kakaretso ea tsamaiso ea PV. Li-PCB tsa morao-rao tse nang le mefuta e mengata e nang le mocheso o phahameng oa mocheso li bohlokoa ho laola mocheso, e leng ntho e ka sehloohong e nahanang ka lisebelisoa tsa elektronike tse matla tse sebelisoang lits'ebetsong tsa photovoltaic.

2.2 Balaoli ba Tefiso le Tsamaiso ea Matla

Balaoli ba litefiso ba laola ho phalla ha motlakase pakeng tsa liphanele tsa photovoltaic le libeteri tse ka ntle ho grid kapa li-setups tse nyalisitsoeng. Li thibela ho tjhaja ho feteletseng le ho tjhatjheha ho tebileng ha dibetri, ho lelefatsa bophelo ba betri le ho boloka botsitso ba sistimi. Potoloho ea " charger controller", e behiloeng holim'a PCB, hangata e kenyelletsa theknoloji ea pulse wide modulation (PWM) kapa maximum power point tracking (MPPT), tseo ka bobeli li netefatsang hore liphanele tsa letsatsi li sebetsa ka matla a tsona a nepahetseng.

• Balaoli ba PWM ba fana ka mekhoa ea motheo ea ho laola tefiso, ha balaoli ba MPPT ba fetola ka matla litšobotsi tsa motlakase oa mojaro ho eketsa matla a ho hapa matla ho tloha ho photovoltaic array.

Tšebeliso ea lisebelisoa tsa PCB tse lahleheloang haholo, tse kang FR4 kapa polyimide, li thusa ho fokotsa tahlehelo ea matla ho potoloha, ho ntlafatsa le ho feta ho ntlafatsa bokhoni ba molaoli oa tefiso.
