Kusanthula kwachuma kwa makina aposachedwa a photovoltaic + Home Power

Pulojekiti yopangira magetsi yapanyumba ya photovoltaic imatsimikiziridwa ndi kampani ya grid kuti igwiritsidwe ntchito pogwiritsa ntchito grid. Ndiye ndizotheka bwanji kukonzekeretsa polojekiti yapanyumba ya photovoltaic system ndi anyumba power bank? Kodi mtengowo ungabwezedwe zaka zingati? Ndipo kodi mkhalidwe wogwiritsiridwa ntchito padziko lonse lapansi ndi wotani? M'nkhaniyi, tikambirana za kusanthula kuthekera kwamakono amakono a photovoltaic solar system kasinthidwe mphamvu kunyumba kuchokera milandu itatu. M'madera ena otukuka, mtengo wogwiritsira ntchito magetsi ndi wokwera kwambiri, ndipo ma gridi onse sali okhazikika komanso odalirika. Chifukwa chake, kuchepetsa mtengo wamagetsi wamba ndiye gwero lalikulu la kukhazikitsa magetsi apanyumba. Kutengera momwe magetsi amagwiritsidwira ntchito pa munthu aliyense, kugwiritsa ntchito magetsi kwa Germany/USA/Japan/Australia kudzakhala 7,035/12,994/7,820/10,071 kWh motsatana mu 2021, zomwe ndi 1.8/3.3/1.99/2.56 nthawi za China. kugwiritsa ntchito magetsi (3,927kWh) munthawi yomweyo. Kuchokera pamalingaliro amitengo yamagetsi, mitengo yamagetsi okhala m'malo otukuka padziko lonse lapansi ndiyokweranso kwambiri. Malinga ndi ziwerengero za Global Petrol Prices, avareji mitengo yamagetsi okhala ku Germany/United States/Japan/Australia mu June 2020 ndi 36/14/26/34 cents/kWh, yomwe ndi nthawi 4.2/1.65/3.1/4 ya nyumba yaku China. mtengo wamagetsi (masenti 8.5) nthawi yomweyo. Nkhani 1:Australia Zokhalamo dzuwa mphamvu zamagetsi kunyumba Mtengo wamagetsi ku Australia uli ndi zinthu zambiri, kutengera kukula kwa nyumba yanu komanso kuchuluka kwa zida zomwe mumagwiritsa ntchito tsiku lililonse. Komabe, mphamvu yamagetsi yapadziko lonse ku Australia ndi 9,044 kWh pachaka kapena 14 kWh patsiku. Tsoka ilo, m'zaka zitatu zapitazi, ndalama zamagetsi zapakhomo zakwera ndi zoposa $550. Zida zamagetsi ndi mphamvu zapakhomo zikuwonetsedwa patebulo ili:

Avereji yamagetsi a mwezi uliwonse a nyumbayi ku Australia ndi pafupifupi 650 kWh, ndipo avareji yamagetsi amagwiritsa ntchito 7,800 kWh pamwezi. Malinga ndi lipoti la mtengo wamagetsi la bungwe la Australian Energy Market Council, pafupifupi ndalama zonse za magetsi ku Australia chaka chino zawonjezeka ndi $100 kuposa chaka chatha, kufika $1,776, ndipo pafupifupi ndalama zamagetsi pa kilowatt-ola ndi masenti 34.41: Kuwerengeredwa ndi 7,800 kilowatt-maola amagetsi pachaka: Bili yamagetsi yapachaka=$0.3441*7800kWh=$2683.98 Off pa Grid Home Power Systems Solution Malinga ndi momwe nyumbayi idakhalira, tidapanga gawo limodzi la gawo limodzi la batire ya Solar. Mapangidwewa amagwiritsa ntchito ma modules a 12 500W, ma modules a 6kW, ndikuyika 5kW bidirectional inverters yosungirako mphamvu, yomwe imatha kupanga 580 ~ 600kWh yamagetsi pamwezi pamwezi. Mphamvu ya Photovoltaic ingagwiritsidwe ntchito nthawi ina, ndi BSLBATT7.5kWh lithiamu batire mphamvu yosungirakoimakonzedwa molingana ndi nthawi yogwiritsira ntchito mphamvu ya 6-hour pachimake, yomwe imagwiritsidwa ntchito ponyamula mphamvu panthawi yamphamvu popanda kuwala kwa dzuwa. Mphamvu yanyumba ya solar yonse imatha kukwaniritsa zosowa zamakasitomala zamagetsi. Kusanthula kwachuma kwachuma: Pakalipano, mtengo wa photovoltaic systems ndi $ 0.6519 / W, ndipo mtengo wa mabatire otsika kwambiri osungira mphamvu ndi pafupifupi $ 0.2794 / Wh. Ndalama zosungira mphamvu za 5kW + BSLBATT 7.5kWh Powerwall batire ndi pafupifupi $6000, ndipo ndalama zake zazikulu ndi izi:

Mlandu wa 2: Ogwiritsa ntchito ogulitsa makeke aku America okha Zida zake zamagetsi ndi mphamvu zake zikuwonetsedwa patebulo ili:

Sitoloyi ili ku Texas, ndipo pafupifupi mwezi uliwonse amagwiritsa ntchito mphamvu pafupifupi 1400 kWh. Mtengo wamagetsi wamalonda pamalo ano ndi 7.56 cents/kWh: Malinga ndi kuwerengetsera, ndalama ya mwezi uliwonse yamagetsi ya wamalonda wosinthidwa=$0.0765*1400kWh=$105.84 Off pa Grid Home Power Systems Solution Malinga ndi momwe wogwiritsa ntchitoyo alili, dongosololi limatenga njira ya batri yokhala ndi magawo atatu. Dongosololi lapangidwa kuti ligwiritse ntchito ma module a 24 500W, ma modules a 12kW, ndi 10kW njira ziwiri zosungira mphamvu zosungira mphamvu, zomwe zimatha kupanga ma 1,200 kilowatt-maola amagetsi pamwezi pafupifupi, zomwe zimakwaniritsa zosowa zamagetsi za kasitomala. Malinga ndi magwiridwe antchito a sitolo ya keke, katundu wambiri amangokhalira kugwiritsira ntchito mphamvu kwambiri masana, ndipo katunduyo ndi wochepa usiku. Choncho, mphamvu ya photovoltaic ingagwiritsidwe ntchito makamaka panthawi yogwiritsira ntchito mphamvu zowonjezera mphamvu, zowonjezeredwa ndi batri lanyumba la dzuwa ndi gridi; itha kugwiritsidwa ntchito makamaka usiku mphamvu yamagetsi yamagetsi yamagetsi yamagetsi, mphamvu ya gridi monga chowonjezera; Choncho, nyumba yosungirako mphamvu ndi zida BSLBATT 15kWh
