Ha tlhokahalo ea matla a tsitsitseng a ntse a hōla, motlakase oa photovoltaic (PV) o fetohile tharollo e ka sehloohong. Le hoja lintlha tse ngata li susumetsa katleho ea tsamaiso ea PV, karolo e 'ngoe e atisang ho hlokomolohuoa ke khetho e nepahetseng ea lithapo tsa photovoltaic. Ho khetha lithapo tse nepahetseng ho ka ntlafatsa haholo phetiso ea matla, polokeho le bophelo bo bolelele ba sistimi. Sengoliloeng sena se fana ka malebela a sebetsang, a tsepamisitse maikutlo ho khethoeng ha thapo ea PV, ho holisa ts'ebetso e ntle ea tlhahiso ea matla ea sistimi ea hau.
1. Khetha Boemo bo PhahamengLithapo tsa PV
Lithapo tsa boleng bo holimo tsa PV ke motheo oa sistimi e sebetsang hantle le e sireletsehileng ea letsatsi. Netefatsa hore lithapo li ikamahanya le maemo a machaba joalo kaTÜV, UL 4703, leIEC 62930, kaha litifikeiti tsena li tiisa ho tšoarella le ts'ebetso.
Likhetho tse tummeng tsa cable tse kangEN H1Z2Z2-KleTUV PV1-Fli etselitsoe tšebeliso ea nako e telele litsing tsa letsatsi, tse fanang ka:
- Ho hanyetsa motlakase ho tlase bakeng sa phetiso e nepahetseng ea matla.
- Tšireletso khahlanong le maemo a tikoloho joalo ka mahlaseli a UV le mongobo.
- Ho hanyetsa mollo ho fokotsa likotsi tse ka bang teng.
Ho tsetela ka likhoele tsa boleng bo holimo ho fokotsa tahlehelo ea matla le ho lelefatsa bophelo ba sistimi ea hau.
2. Nahana ka boholo ba Cable le bokhoni ba ho jara hona joale
Boholo ba thapo bo ama ka kotloloho katleho ea phetiso ea matla. Lithapo tse tlase haholo li ka lebisa ho theoheng ho matla ha motlakase, ho baka tahlehelo ea matla le mocheso o feteletseng.
Bakeng sa litsamaiso tse ngata tsa PV, boholo bo sebelisoang hangata bo4mm² or 6mm², ho itšetlehile ka bokhoni ba tsamaiso le bolelele ba cable. Netefatsa hore thapo e khethiloeng e na le matla a ho tsamaisa hona joale a loketseng bakeng sa ts'ebetso ea hau ho boloka ts'ebetso le polokeho.
3. Bea Pele Lintho Tse Fapaneng le Boemo ba Leholimo le tse Tšoarellang
Lithapo tsa photovoltaic li tlameha ho mamella mathata a fapaneng a tikoloho. Batla lithapo tse nang le:
- Tšireletso e hanyetsanang le UV le ozoneho mamella ho ba letsatsing nako e telele.
- Thepa e thibelang malakabe e lumellana leIEC 60332-1bakeng sa polokeho ea mollo.
- Mocheso oa ho sebetsa o tloha ho-40°C ho ea ho +90°Cho sebetsana le maemo a feteletseng.
Lisebelisoa tse kangTPE or XLPEli loketse bakeng sa ho kenya letsoho, ho netefatsa ho tenyetseha le ts'ebetso e tšoarellang nako e telele.
4. Sebelisa likhokahano tse nepahetseng tsa Cable le ho Felisoa
Likhokahano tse sireletsehileng le tse tsitsitseng li bohlokoa bakeng sa ho fokotsa tahlehelo ea matla. Sebelisa lihokelo tsa boleng bo holimo, joalo kaLihokelo tsa MC4, ho thibela ho felloa ke matla kapa ho seretse.
Kamehla hlahloba likhokahano ho netefatsa hore li lula li tiile 'me ha li na litšila kapa mongobo. Ho kenya le tlhokomelo e nepahetseng ea likhokahano ho kenya letsoho phetisong ea matla e tšepahalang le botsitso ba sistimi.
5. Fokotsa ho theoha ha Voltage ka Optimized Cable Layouts
Ho matha ha cable ka nako e telele ho ka baka ho theoha ho hoholo ha motlakase, ho fokotsa ts'ebetso ea sistimi. Ho fokotsa litahlehelo tsena:
- Sebelisa bolelele ba lithapo tse khutšoane ha ho khoneha.
- Ntlafatsa tsela ea lithapo ho fokotsa ho kobeha ho sa hlokahaleng le bolelele bo eketsehileng.
- Khetha lithapo tse nang le sebaka se seholo sa li-cross-sectional bakeng sa ho kenya tse hlokang ho matha halelele.
Maano ana a netefatsa phepelo e nepahetseng ea matla ho tloha liphanele tsa letsatsi ho ea ho li-inverters.
6. Netefatsa Theko e Nepahetseng le Tšireletso
Ho beha fatše ho bohlokoa bakeng sa polokeho ea sistimi le ts'ebetso. Lithapo tsa fatše li thusa ho sireletsa khahlanong le ho phahama ha motlakase le ho tsitsisa tsamaiso nakong ea ts'ebetso.
Ntle le moo, khetha likhoele tse nang le insulation e nepahetseng le tšireletso ho fokotsa litlamorao tsa tšitiso ea motlakase (EMI) le ho netefatsa ts'ebetso e ts'oanang.
7. Hlokomela le ho Boloka Lithapo tsa PV Kamehla
Tlhokomelo ea kamehla e bohlokoa ho boloka sistimi ea hau ea PV e le maemong a holimo. Nako le nako hlahloba lithapo bakeng sa matšoao a ho khathala, ho senyeha kapa ho bola. Sireletsa lithapo likotsing tsa tikoloho, joalo ka litoeba kapa mongobo o feteletseng, o sebelisa lisebelisoa tsa taolo ea likhoele joalo ka likotopo, lithae kapa likotopo.
Ho hloekisa le ho hlophisa likhoele tsa hau khafetsa ha ho ntlafatse ts'ebetso feela empa hape ho eketsa nako ea bophelo ea sistimi eohle.
Qetello
Ho khetha le ho boloka lithapo tse nepahetseng tsa PV ke mohato oa bohlokoa oa ho ntlafatsa tlhahiso ea matla a photovoltaic. Ka ho etelletsa pele thepa ea boleng bo holimo, boholo bo nepahetseng, meralo e sebetsang hantle, le tlhokomelo ea kamehla, o ka ntlafatsa ts'ebetso le bophelo bo bolelele ba sistimi ea hau.
Ho tsetela ka likhoele tsa pele le ho latela mekhoa e metle ha ho matlafatse phepelo ea motlakase feela empa hape ho fokotsa litšenyehelo tsa nako e telele. Nka bohato ba pele ba ho holisa bokhoni ba solar system ea hau ka ho ntlafatsa likhoele tsa hau le ho etsa bonnete ba ho kenya le tlhokomelo e nepahetseng.
Ntlafatsa sistimi ea hau ea matla a letsatsi kajeno bakeng sa bokamoso bo khanyang, bo tsitsitseng haholoanyane!
