ʻEhia ke kumu kūʻai ʻana o ka Batri Solar Home no kēlā me kēia kWh?

He aha ke kumukūʻai o ka pā hale solar home no kWh? Pono paha ʻoe i kahi waihona pākaukau noho no kāu ʻōnaehana photovoltaic? Ma ʻaneʻi e ʻike ai ʻoe i nā pane. He ʻokoʻa ke kumukūʻai o ka hoʻohana ʻana i ka pā uila home, ma muli o ka nuiʻoihana pākaukau lā. I ka wā ma mua, ua hoʻohana mākou i nā pākaʻi lead-acid e mālama i ka ikehu lā. ʻOiai ʻo ka ʻenehana no nā pākika lead-acid he ʻano makua, ʻo ke kumukūʻai i manaʻo ʻia no ka hola kilowatt hiki ke $500 a $1,000! Ke hoʻololi mālie nei nā ʻenekini lā Lithium-ion i nā pākī lead-acid ma ke ʻano he hanauna hou o nā ʻōnaehana hoʻihoʻi pākaukau home ma muli o ko lākou kiʻekiʻe kiʻekiʻe, ʻoi aku ka hiki ke loaʻa a me ka lōʻihi o ka lawelawe ʻana, akā hele mai lākou me ke kumu kūʻai kiʻekiʻe, no laila ke kumukūʻai i manaʻo ʻia no kēlā me kēia. ʻO kWh no nā pākahi lā home lithium-ion he $800 a i $1,350. He mea pono anei i ka home solar? Hoʻopuka nā Photovoltaics i ka uila mai ka lā. No laila, hiki i ka ʻōnaehana photovoltaic ke hoʻoulu i ka ikehu nui i ka wā e ʻā ana ka lā. Pili kēia i ka manawa mai ke kakahiaka a i ke ahiahi. Eia kekahi, loaʻa iā ʻoe ka nui o ka uila i ka puna, ke kauwela a me ka hāʻule. ʻO ka mea pōʻino, ʻo ia hoʻi nā manawa e pono ai kou ʻohana i ka uila liʻiliʻi. ʻOi aku ka nui o ka hoʻohana ʻana i ka uila i nā hola ahiahi a me nā mahina hoʻoilo pōʻeleʻele. No laila, i ka hōʻuluʻulu ʻana, ʻo ia ke ʻano: ● Hāʻawi ka ʻōnaehana i ka uila liʻiliʻi i ka wā e pono ai ʻoe. ●Ma kekahi ʻaoʻao, nui ka uila i hana ʻia i ka manawa me ka noi haʻahaʻa. No laila, ua hana ka luna kānāwai i ka hiki ke hānai i ka mana o ka lā āu e pono ʻole ai i ka pā ākea. Loaʻa iā ʻoe kahi uku hānai no kēia. Eia nō naʻe, pono ʻoe e kūʻai i kāu uila mai nā mea hoʻolako ikehu lehulehu i nā manawa o ke koi kiʻekiʻe. ʻO ka hopena maikaʻi loa e hiki ai ke hoʻohana pono i ka uila iā ʻoe iho he ʻōnaehana hoʻihoʻi pākaukau no kāu ʻōnaehana photovoltaic. ʻAe kēia iā ʻoe e mālama i ka uila keu a hiki i kou wā e pono ai. Pono anei au i ka ʻōnaehana pākahi lā home no kaʻu ʻōnaehana photovoltaic? ʻAʻole, hana pū kekahi photovoltaics me ka ʻole o ka waiho ʻana i ka pākaukau. Eia nō naʻe, i kēia hihia, e nalowale ana ke koena uila i nā hola kiʻekiʻe no kāu ʻai ponoʻī. Eia kekahi, pono ʻoe e kūʻai i ka uila mai ka pā lehulehu i nā manawa o ke koi kiʻekiʻe. Loaʻa iā ʻoe ka uku no ka uila āu e hānai ai i ka pā, akā hoʻolilo ʻoe i ke kālā ma kāu mau kūʻai. Hiki paha iā ʻoe ke uku no ia mea ma mua o kāu loaʻa ma ka hānai ʻana iā ia i loko o ka pā. Eia kekahi, ua hoʻokumu ʻia kāu loaʻa kālā mai ka uku hānai ma nā kānāwai kānāwai, hiki ke hoʻololi a hoʻopau ʻia paha i kēlā me kēia manawa. Eia kekahi, uku wale ʻia ka uku hānai no ka manawa o 20 mau makahiki. Ma hope o kēlā, pono ʻoe e kūʻai aku i kāu uila iā ʻoe iho ma o nā brokers. ʻO ke kumukūʻai makeke no ka mana solar i kēia manawa ma kahi o 3 keneta no ka hola kilowatt. No laila, pono ʻoe e hoʻāʻo e hoʻohana i ka nui o kou mana solar e like me ka hiki iā ʻoe iho a no laila e kūʻai liʻiliʻi i ka hiki. Hiki iā ʻoe ke hoʻokō i kēia me kahi ʻōnaehana mālama pākaukau home e kūlike i kāu photovoltaics a me kāu pono uila. He aha ka manaʻo o ka helu kWh e pili ana i ka mālama ʻana i ka pā hale solar? ʻO ka hola kilowatt (kWh) he ʻāpana o ke ana o ka hana uila. Hōʻike ia i ka nui o ka ikehu i hana ʻia e kekahi mea uila (generator) a i ʻole e ʻai ai (mea kūʻai uila) i hoʻokahi hola. E noʻonoʻo i kahi ʻōpuʻu kukui me ka mana o 100 watts (W) e ʻā ana no 10 mau hola. A laila ua hopena kēia: 100 W * 10 h = 1000 Wh a i ʻole 1 kWh. No nā ʻōnaehana mālama pākaukau home, e haʻi kēia kiʻi iā ʻoe i ka nui o ka ikehu uila hiki iā ʻoe ke mālama. Inā hōʻike ʻia kēlā ʻōnaehana mālama pākaukau home he 1 kilowatt hola, hiki iā ʻoe ke hoʻohana i ka ikehu i mālama ʻia e hoʻomau i ka ʻā ʻana o ka ʻōpuʻu kukui 100-watt i ʻōlelo ʻia ma luna no 10 mau hola. Akā ʻo ka manaʻo, pono e hoʻopiha piha ʻia ka mālama ʻana o ka pā hale solar! I ka manawa hea e pono ai ka ʻōnaehana hoʻihoʻi pākaukau no ka home? E like me nā haʻawina i hōʻike ʻia, hiki iā ʻoe ke hoʻohana wale i ka 30% o ka uila i hana ʻia e kāu ʻōnaehana photovoltaic iā ʻoe iho. Me ka hoʻohana ʻana i kahipanakō pilaki home solar, piʻi kēia waiwai i 70% - 80 %. I mea e loaʻa ai ka waiwai, ʻaʻole pono e ʻoi aku ke kumukūʻai o ka hola kilowatt mai kāu waihona pākaukau home solar ma mua o ka hola kilowatt i kūʻai ʻia mai ka pā lehulehu. Pūnaehana Photovoltaic me ka ʻole o ka waihona pākaukau home solar No ka hoʻoholo ʻana i ka amortization o kahi ʻōnaehana photovoltaic me ka ʻole o ka waihona pākaukau home solar, hoʻohana mākou i kēia mau hiʻohiʻona waiwai: ●Ke kumu kūʻai o nā modula lā me 5 kilowatt peak (kWp) puka: 7500 kālā. ●Nā koina hou (no ka laʻana pili o ka ʻōnaehana): 800 kālā. ●Ka huina o na koina no ke kuai ana: 8300 dala ʻO nā modula o ka lā me ka huina o ka 1 kilowatt peak e hoʻopuka ma kahi o 950 kilowatt hola i kēlā me kēia makahiki. No laila, ʻo ka huina o ka hua no ka ʻōnaehana he 5 kilowatt peak (5 * 950 kWh = 4,750 kWh i kēlā me kēia makahiki). Ua like kēia me nā pono uila makahiki o kahi ʻohana o 4. E like me ka mea i ʻōlelo mua ʻia, hiki iā ʻoe ke hoʻopau wale ma kahi o 30% a i ʻole 1,425 kilowatt hola iā ʻoe iho. ʻAʻole pono ʻoe e kūʻai i kēia nui o ka uila mai ka lehulehu. Ma ke kumu kūʻai o 30 keneta no ka hola kilowatt, mālama ʻoe i 427.5 kālā i nā koina uila makahiki (1,425 * 0.3). Ma luna o kēlā, loaʻa iā ʻoe he 3,325 kilowatt-hola ma ka hānai ʻana i ka uila i loko o ka pā (4,750 - 1,425). Ke emi nei ka uku hānai i kēlā me kēia mahina ma ka pākēneka o 0.4 pakeneka. No ka manawa kōkua o 20 mau makahiki, pili ka uku hānai no ka mahina i hoʻopaʻa inoa ʻia ai ka mea kanu a kau ʻia. I ka hoʻomaka ʻana o 2021, ʻo ka uku hānai ma kahi o 9 keneta no ka kilowatt-hola. 'O ia ho'i, he 299,25 dala (3,325 kWh * 0,09 euros) ka loa'a 'ana mai o ka uku hānai. No laila, ʻo 726.75 kālā ka nui o ka mālama ʻana i nā kumukūʻai uila. No laila, ʻo ka hoʻokomo ʻana i ka mea kanu e uku iā ia iho ma kahi o 11 mau makahiki. Eia naʻe, ʻaʻole kēia e noʻonoʻo i nā kumukūʻai mālama makahiki no ka ʻōnaehana o approx. 108.53 euros. Pūnaehana Photovoltaic me ka mālama ʻana i ka pā hale lā Manaʻo mākou i ka ʻikepili kanu like i ʻōlelo ʻia ma ka helu mua. Wahi a kekahi lula o ke koʻokoʻo, pono e loaʻa ka mana o ka ʻōnaehana kiʻi kiʻi kiʻi i ka lithium ion solar battery bank. No laila, ʻo kā mākou ʻōnaehana me 5 kilowatts peak e loaʻa i kahi hoʻihoʻi ʻana o ka pā uila home me ka mana o 5 kilowatts peak. Wahi a ke kumu kūʻai maʻamau o 800 kālā no ka kilowatt-hola o ka hiki ke mālama ʻia i ʻōlelo ʻia ma luna nei, ʻo ke kumukūʻai o ka waihona he 4000 kālā. ʻO ke kumu kūʻai no ka mea kanu ke piʻi nei i ka huina o 12300 kālā (8300 + 4000). I kā mākou hiʻohiʻona, e like me ka mea i haʻi mua ʻia, hana ka mea kanu i 4,750 kilowatt-hola i kēlā me kēia makahiki. Eia nō naʻe, me ke kōkua o ka pahu mālama, hoʻonui ka hoʻohana ponoʻī iā 80 % o ka nui o ka uila i hana ʻia a i ʻole 3800 kilowatt-hola (4,750 * 0.8). No ka mea ʻaʻole pono ʻoe e kūʻai i kēia nui o ka uila mai ka lehulehu, e mālama ʻoe i kēia manawa he 1140 kālā i nā kumukūʻai uila ma ke kumukūʻai uila o 30 keneta (3800 * 0.3). Ma ka hānai ʻana i ke koena 950 kilowatt-hola (4,750 – 3800 kWh) i loko o ka pā, loaʻa iā ʻoe kahi 85.5 kālā hou i kēlā me kēia makahiki (950 * 0.09) me ka uku hānai i ʻōlelo ʻia ma mua o 8 keneta. He 1225.5 kālā kēia e ho'ōla ai i ka makahiki. E uku ka mea kanu a me ka ʻōnaehana mālama iā lākou iho ma kahi o 10 a 11 mau makahiki. Eia hou, ʻaʻole mākou i noʻonoʻo i nā kumukūʻai mālama makahiki. He aha kaʻu e hoʻolohe ai i ke kūʻai ʻana a me ka hoʻohana ʻana i nā pākahi solar home? Ma muli o ka ʻoi aku ka maikaʻi a me ka lōʻihi o ke ola ʻana ma mua o nā pākaukau alakaʻi, pono ʻoe e kūʻai i kahi waiho ʻana o ka pā hale me nā pā lithium-ion. E hōʻoia i hiki i ka pā hale lā ke kūpaʻa ma kahi o 6,000 mau pōʻaiapili a loaʻa nā makana mai nā mea hoʻolako. Nui nō hoʻi nā ʻokoʻa kumu kūʻai no nā ʻōnaehana mālama pākaukau o kēia wā. Pono ʻoe e hoʻokomo i ka waihona pākaukau solar home ma kahi anuanu i loko o ka hale. Pono e hōʻalo ʻia nā wela ma luna o 30 degere Celsius. ʻAʻole kūpono nā mea hana no ka hoʻokomo ʻana ma waho o ka hale. Pono ʻoe e hoʻopau i kalithium ion solar bateriamau. Inā noho lākou ma lalo o ka uku piha no ka manawa lōʻihi, he hopena maikaʻi kēia i ko lākou ola. Inā ʻoe e hahai i kēia mau ʻōlelo aʻoaʻo, ʻoi aku ka lōʻihi o ka waihona pākaukau solar home ma mua o ka manawa hoʻohiki 10 makahiki i hāʻawi mau ʻia e nā mea hana. Me ka hoʻohana kūpono, 15 mau makahiki a ʻoi aku ka mea maoli.
