He māmā noa te ahua o te whakatauranga "120W", engari ka tere te ako a ngā kaihoko ka rerekē te putanga o te ao tūturu i runga i te hihi o te rā, te pāmahana, te koki, me te taputapu e utua ana e koe. Mena kei te hoko koe i tētahiPūrere Rā Whakapiko 120WMō te puni, te haere RV, te taunga whenua, te tautoko ā-whatumanawa rānei, ko te pātai whaihua tēnei: e hia ngā watts me ngā watt-haora ka riro i a koe i te rā—ā, he aha te mea ka taea e tēnā te whakahaere?
Anei tētahi huarahi ngaio, e ahu mai ana i ngā tau, hei whakatau tata i te putanga me te whiriwhiri i te tatūnga tika.
1) He aha te tikanga o te "120 Watts"
Ko te nuinga o ngā panera rā e whakatauria ana kiSTC (Ngā Tikanga Whakamātautau Paerewa): 1000 W/m² te hihi, 25°C te pāmahana pūtau, me te whānuitanga pai rawa atu. I te parae, he onge ngā āhuatanga STC.
He ture pai mō tētahi paparanga takai kounga teitei 120W:
- Mana tūturu noa:~70–100Wi te rā kaha (mārama te rā, pai te koki)
- Ngā tihi pai rawa atu:tera pea ka kite koe i te wa poto110–120Wme te tūnga tino tika me ngā pāmahana matao
- Ngā āhuatanga kino: 10–60Wi ngā rangi kohu, i te atarangi wāhanga, i te koki kino rānei
He nui ake te hiranga o te wera i tā te tini o te tangata e whakaaro nei. I te wera haere o ngā pūtau rā, ka heke te ngaohiko. He maha ngā panera he tauwehenga pāmahana kei te tata ki-0.3% ki te -0.4% ia °C(he rerekē i runga i te momo pūtau). I te rā wera, ka taea e tēnā te whakaheke i te kaha o runga ahakoa i raro i te rā kanapa.
2) Pūngao o ia rā: Tahurihia ngā Watts ki ngā Hāora-Watt
Ko te mea ka taea e koe te whakahaere, kei runga ipūngao ia rā, i inehia i roto i ngā haora-watt (Wh). He whakatau tata māmā:
Wh o ia rā ≈ Ngā watts o te papa × Ngā Hāora Rā Nui × Te whai huatanga o te pūnaha
Ko te whai huatanga noa o te pūnaha (pūmana + taura + ngaronga huringa) mō te pūngao rā kawe he maha tonu te wā70–85%.
Ngā tauira mō tētahi Pūnaha Rā Whakapiko 120W:
- He rā raumati pai (5 ngā hāora tino pai o te rā):
120W × 5h × 0.8 ≈480Wh/rā - Ngā āhuatanga toharite (3.5 ngā hāora pīka o te rā):
120W × 3.5h × 0.8 ≈336Wh/rā - Wā kapua/wā pakihiwi (2 hāora pīkari o te rā):
120W × 2h × 0.8 ≈192Wh/rā
Nō reira, i roto i ngā haerenga tūturu maha, me tumanako pea200–500Wh ia rāi runga i te wāhi me te rangi.
3) He aha te mana ka taea e taua mea?
Anei ngā tauira tūturu e whakamahi ana i~350Wh/rāhei putanga waenga-awhe:
- Te utunga waea (10–15Wh mō ia utunga katoa):~20–30 ngā utu
- Papa (25–35Wh):~10–14 ngā utu
- Pona rorohiko (50–80Wh):~4–6 ngā utu
- Pouaka whakamātao pēhi 12V (300–700Wh/rā te tikanga, i runga i te wera me te huringa mahi):
Tērā pea ka taupokina e te papa hiko 120Wwāhangao te kai o ia rā, ā, ka taea te taupoki katoa i te rangi ngawari me te rā pai—ina koa mēnā ka honoa ki te rokiroki pākahiko e tika ana.
Mō ngā taputapu AC, kia maumahara ka tāpirihia e te inverter ngā mate. Ko te whakahaere i tētahi taputapu 60W mō ngā hāora e 5 he mea nui.300Wh, engari whakamahere kia tata atu ki330–360Whi muri i te koretake o te inverter.
4) He aha i rerekē ai te mahi a ngā kōwae takai i ngā panera pakari
A Pūrere Rā Whakapiko 120Whe mea hanga mō te kawe ngāwari, ehara i te mea he tino pai te whakairi ki te tuanui. Ngā āhuatanga matua e pā ana ki te mahi hei tirotiro māu:
- Ngā pūtau tino whai hua:he maha ngā panera kawe utu nui e whakamahi ana i ngā pūtau mono huri noa20–23%te whai huatanga, e āwhina ana i te iti o te horahanga o te mata.
- Momo kaiwhakahaere: MPPThe nui ake te kaha e kohia ana i te PWM, he maha tonu ngā wā10–25% ngā huai te rangi makariri, i te wā rānei he nui ake te ngaohiko o te panera i te ngaohiko o te pākahiko.
- Ngā tūnga whana / te whakatikatika koki:mā te arotahi ki te papaaho ka taea te whakapai ake i te putanga mā te20–40%hei whakataurite ki te whakatakoto papatahi.
- Te ātete ki te atarangi:Ahakoa te atarangi iti, ka taea e ia te whakaiti nui i te hiko. He ngāwari ake te whakamahi i ngā panera me te whakatakotoranga aho ātaahua, engari he tino pai tonu te atarangi.
5) Rārangi Arowhai Kaihoko Tere
Hei hanga i tētahi mahere hoko pono:
- Kōwhiria te atanga putanga tika:MC4mō ngā whakaputa hiko/pūmana pūngao rā; USB-C PD mēnā ka utua tika e koe ngā taputapu.
- Whakamahia ngā taura poto, matotoru hei whakaiti i te hekenga ngaohiko (ina koa i ngā panera 12–20V).
- Tāpirihia ki te pākahiko: he wā poto te whakamahinga o te hiko o te rā; ka taea te whakamahi i roto i te rokiroki.
- Whakaritea te koki me te tūnga matua: kaua e whakamarumaruhia, ka anga anō kia 2–3 ngā wā i te rā kia pai ai te hua.
Raina Matua
Ka taea e te papa rā 120W te whakaputatae atu ki te 120Wi roto i ngā āhuatanga tino pai, engari me tumanako te nuinga o ngā kaiwhakamahi70–100Wi te wā e kaha ana te rā, me te tata ki200–500Wh ia rāi runga i ngā hāora pīka o te rā me ngā ngaronga o te pūnaha. Mēnā ka kōrero mai koe ki ahau i tō wāhi/wā, he aha tāu e hiahia ana ki te whakahaere (pouaka whakamātao, pona, tauira teihana hiko), me te mea ka whakamahia e koe te MPPT, ka taea e au te whakatau tata i tō pūngao o ia rā me te tūtohu atu mēnā he nui te 120W, mēnā rānei me whakanui ake te rahi.
