5 units × 120kW = 1.3 Iminyaka yokubuyisa izindleko
Kwadalwa ngo 12.19
I. Ukumiswa kwe-Transformer
Ukubala Ikhono
Amandla ngepali yokushaja: 120kW
Isamba sokudinga amandla: 5 izinhlelo x 120kW = 600kW.
Ukucabangela umthwalo wangempela: Izinsika zokushaja ngokuvamile azisebenzi ngempela umthwalo ophelele ngasikhathi sinye, ngakho-ke kufanele kuqaliswe isilinganiso sokusetshenziswa esihambisanayo (0.7-0.8).
Okuncane okudingekayo: 600kW x 0.7 = 420kW
Iphakheji elincomekayo: Ukuze kubhekwane ne-factor yamandla (cishe 0.9) kanye nomkhawulo, khetha i-transformer ye-box-type engu-630kVA.
Izidingo Zobuchwepheshe
Ibanga le-voltage: 380V uhlelo lwezintambo ezine lwezinyathelo ezintathu
Indlela yokupholisa: ukupholisa kwemvelo noma ukupholisa komoya okwenziwayo.
Izinga lokuvikela: IP54 noma ngaphezulu (ukuvikela uthuli nokungangeni kwamanzi)
II. Ukuhlola Izindleko
Izindleko zezimboni nezokufaka
Izinsika zokushaja: 5 x CNY 35,000/set ≈ CNY 175,000.
Transformer: 630kVA ibhokisi transformer (kuhlanganisa ukufakwa) ≈ CNY 120,000-180,000.
Izinsiza ezisekelayo: amakhebuli, amakhabethe wokwabiwa kwamandla, izinhlelo zokubheka, njll. ≈ CNY 60,000-100,000.
Izindleko Zesayithi: Uma udinga ukuqasha izikhala zokupaka ezinhlanu, irenti yonyaka ingaba cishe CNY 15,000-30,000 (kuya ngendawo).
Izindleko Zokufinyelela Epulatifomu
Umgomo wokuqala: imali yokutshala: imali yokubhalisela ipulatifomu kanye nokwakhiwa kwesistimu yokuphatha ≈ CNY 30,000-50,000.
Imali yokusebenza nok upkeep yonyaka: imali yesevisi yesoftware + ukuphathwa ngesandla ≈ CNY 80,000-120,000 /unyaka.
Inani lokutshala lokuqala
Izindleko ezihlanganisiwe zokufaka, ukufaka imishini kanye nokufinyelela epulatifomu:
CNY 175,000 (ukushaja) + CNY 150,000 (i-transformer) + CNY 80,000 (ukweseka) + CNY 50,000 (ipulatifomu) ≈ CNY 455,000.
(ukuhlukanisa izindleko ezingase zibe khona ezifana nokuqashwa kwesayithi nezindleko zokwandisa amandla kagesi).
III. Ukuhlaziywa Kwezimali
Imodeli yokwenzela imali
Izinkolelo:
Isikhathi sokusetshenziswa nsuku zonke sokushaja: amahora angu-6-8 (kubalwa ngenani eliqinile lama-6 amahora)
Ukusebenza kahle kokushaja: 90%
Imali yesevisi: CNY 0.3-0.5/kWh (uthatha i-CNY 0.4 /kWh njengomfanekiso)
Izindleko zikagesi: CNY 0.7-0.8/kWh (intengo ephelele ekhokhwa ngabasebenzisi ingu CNY 1.1-1.3 /kWh).
Imali yonyaka:
5 sets × 120kW × 6h × 365 days× 0.9 ≈ 1,182,600kwh.
Imali engenayo yonyaka:
Imali yokusebenza: 1,182,600 kWh × CNY 0.4≈ CNY 473,000.
Izindleko zikagesi: 1,182,600 kWh × CNY 0.8≈ CNY 946,000 (okuzokhokhwa kwi-grid kagesi).
Izindleko zokusebenza
Izindleko eziqinile: ukuqashwa kwesikhala CNY 30,000 + izindleko zokusebenza nokugcinwa CNY 100,000≈ CNY 130,000 /unyaka.
Inzuzo neto
Uma kuphela izindleko zesevisi ezikhokhwayo, futhi imali kagesi (CNY 946,000) ibhujiswa ngumsebenzisi, ngakho-ke inzuzo net iyona:
CNY 473,000 yuan (imali yokusebenza) - CNY 130,000 yuan (izindleko eziqinile) ≈ CNY 343,000 /unyaka.
IV. Isikhathi Sokubuyiselwa Kwezimali
Imodeli ethembeni (ukusetshenziswa 80%):
Umgomo wokuqala wokutshalwa kwezimali CNY 455,000 ➗ inzuzo ye-annual net CNY 343,000 ≈ 1.3 iminyaka.
Imodeli ye-Conservative (umsebenzi wokusebenzisa 50%):
Inzuzo ye-Annual net CNY 172,000 → isikhathi sokubuyisela sisondele eminyakeni engu-2.6.
V. Izingozi Nezinhlinzeko Zokuthuthukisa
Izingozi ezisemqoka
Ukusetshenziswa okuphansi (ngaphansi kwama-50% kungaholela ezilahlekelweni)
Ukulungiswa kwenqubomgomo yokwaziswa kwamandla kagesi (njengokwehluka kwentengo kagesi phakathi kwezikhathi eziphezulu nezisezingeni eliphansi)
Isikhathi sokuvuma nezindleko zokwandiswa kwamandla (izindleko ezengeziwe zingadingeka kwezinye izindawo)
Ukuthuthukiswa kwemikhombandlela
Ukukhetha indawo ezindaweni ezinamathafa aphezulu (isb. izindawo zokuhweba, izindawo zokusebenza ezisemgwaqweni).
Isu lokub pricing ngesikhathi sokusetshenziswa (ukub pricing okuphezulu phakathi nezikhathi eziphezulu)
Faka isicelo semali yokwesekwa kukahulumeni (amanye amadolobha anemali yokwesekwa ekwakhiweni kwezinsika zokushaja)
VI. Isifinyezo
Isidingo se-Transformer: i-transformer ye-box-type engu-630kVA (cishe CNY 150,000)
Total investment: mayelana ne-CNY 455,000 (engafakiwe irenti yesizinda)
Inkokhelo yonyaka: CNY 343,000 (80% yokusetshenziswa)
Isikhathi sokubuyiselwa: 1.3-2.5 iminyaka (isikhathi sangempela sincike ezinqubweni zendawo nasekusebenzeni kahle)
