Mokhoa oa ho theha sistimi ea matla a letsatsi

Ho bonolo haholo ho kenya sistimi e ka hlahisang motlakase.Ho na le lintho tse hlano tse ka sehloohong tse hlokahalang:

1. Liphanele tsa letsatsi

2. Borakete ea motsoako

3. Lithapo

4. Inverter e amanang le marang-rang ea PV

5. Metara e kentsoeng ke k'hamphani ea marang-rang

Khetho ea solar panel (mojule)

Hajoale, lisele tsa letsatsi 'marakeng li arotsoe ka silicon ea amorphous le silicon ea kristale.Silicon ea crystalline e ka aroloa ka silicon ea polycrystalline le silicon ea monocrystalline.Katleho ea phetoho ea photoelectric ea lisebelisoa tse tharo ke: monocrystalline silicon> polycrystalline silicon> silicon ea amorphous.Crystalline silicon (monocrystalline silicon le polycrystalline silicon) ha e le hantle ha e hlahise hona joale tlas'a leseli le fokolang, 'me silicon ea amorphous e na le khanya e fokolang e ntle (ho na le matla a fokolang tlas'a khanya e fokolang).Ka hona, ka kakaretso, silicon ea monocrystalline kapa polycrystalline silicon lisebelisoa tsa letsatsi tsa letsatsi li lokela ho sebelisoa.

2. Khetho ea tšehetso

Solar photovoltaic bracket ke bracket e khethehileng e etselitsoeng ho beha, ho kenya le ho lokisa lisebelisoa tsa letsatsi tsamaisong ea motlakase ea matla a letsatsi photovoltaic.Lisebelisoa tse akaretsang ke motsoako oa aluminium le tšepe e sa hloekang, tse nang le bophelo bo bolelele ba tšebeletso ka mor'a ho chesa ho chesa.Litšehetso li arotsoe haholo ka mekhahlelo e 'meli: tracking e tsitsitseng le e itekanetseng.Hona joale, litšehetso tse ling tse tsitsitseng 'marakeng le tsona li ka fetoloa ho latela liphetoho tsa nako ea khanya ea letsatsi.Feela joaloka ha e ne e qala ho kenngoa, letsoapo la karolo e 'ngoe le e' ngoe ea letsatsi le ka fetoloa hore le ikamahanye le li-angles tse fapaneng tsa leseli ka ho tsamaisa li-fasteners, 'me motlakase oa letsatsi o ka lokisoa ka nepo sebakeng se boletsoeng ka ho tiisa hape.

3. Khetho ea cable

Joalokaha ho boletsoe ka holimo, inverter e fetola DC e hlahisoang ke motlakase oa letsatsi hore e be AC, kahoo karolo e tsoang ho karolo ea letsatsi ho ea qetellong ea DC ea inverter e bitsoa DC side (DC side), 'me lehlakore la DC le hloka ho sebelisa e khethehileng. photovoltaic DC cable (DC cable).Ntle le moo, bakeng sa lits'ebetso tsa photovoltaic, lisebelisoa tsa matla a letsatsi li sebelisoa hangata maemong a thata a tikoloho, joalo ka UV e matla, ozone, liphetoho tse matla tsa mocheso le khoholeho ea lik'hemik'hale, e bolelang hore likhoele tsa photovoltaic li tlameha ho ba le khanyetso e ntle ea boemo ba leholimo, UV le ozone corrosion resistance. le ho khona ho mamella mefuta e mengata e fapaneng ea liphetoho tsa mocheso.

4. Khetho ea inverter

Pele ho tsohle, nahana ka mokhoa oa liphanele tsa letsatsi.Haeba liphanele tsa letsatsi li hlophisitsoe ka litsela tse peli ka nako e le 'ngoe, ho kgothaletswa ho sebelisa inverter ea ho latela MPPT e peli (MPPT e habeli).Hajoale, e ka utloisisoa e le processor ea mantlha e 'meli,' me motheo o mong le o mong o sebetsana le lipalo ka tsela e le 'ngoe.Ebe u khetha inverter e nang le litlhaloso tse tšoanang ho ea ka matla a kentsoeng.

5. Metering metres (two-way metres) e kentsoeng ke k'hamphani ea marang-rang

Lebaka la ho kenya mochine oa motlakase oa litsela tse peli ke hore motlakase o hlahisoang ke photovoltaic o ke ke oa sebelisoa ke basebelisi, ha motlakase o setseng o hloka ho fetisetsoa ho marang-rang, 'me meter ea motlakase e hloka ho lekanya palo.Ha motlakase oa photovoltaic o sitoa ho finyella tlhokahalo, o hloka ho sebelisa motlakase oa marang-rang, o hlokang ho lekanya palo e 'ngoe.Limithara tse tloaelehileng tsa hora e le 'ngoe ea watt ha li khone ho fihlela tlhokahalo ena, kahoo ho sebelisoa limithara tse bohlale tsa watt hora tse nang le ts'ebetso ea ho lekanya limithara tse peli tsa watt hora.
