ʻEhia ka mana e hana ʻia e kahi panela solar 120 Watt?

 

1) He aha ka manaʻo maoli o "120 Watts"

Ua helu ʻia ka hapa nui o nā panela solar maSTC (Nā Kūlana Hoʻāʻo Maʻamau): 1000 W/m² irradiance, 25°C cell temperature, a me ka spectrum kūpono. Ma ke kula, ʻaʻole pinepine nā kūlana STC.

He lula maikaʻi no kahi panela hiki ke pelu ʻia 120W:

• Mana manawa maoli maʻamau:~70–100Wi ka lā ikaika (awakea, kihi kūpono)
• Nā piko kūlana maikaʻi loa:hiki iā ʻoe ke ʻike no ka manawa pōkole110–120Wme ke kūlike kūpono a me nā mahana anuanu
• Nā kūlana maikaʻi ʻole: 10–60Wi nā lani noe, malu hapa, a i ʻole ke kihi maikaʻi ʻole

ʻOi aku ka nui o ka wela ma mua o ka mea i manaʻo ʻia e ka poʻe he nui. Ke wela nā cell solar, hāʻule ka voltage. He nui nā panela he coefficient mahana a puni-0.3% a i -0.4% no kēlā me kēia °C(ʻokoʻa ia ma muli o ke ʻano o ke kelepona). I kahi lā wela, hiki i kēlā ke kahili i ka mana i ʻike ʻia mai luna mai ʻoiai ma lalo o ka lā ʻālohilohi.

2) Ikehu i kēlā me kēia lā: Hoʻololi i nā Watts i nā Watt-Hours

ʻO ka mea hiki iā ʻoe ke holo ma muli oikehu i kēlā me kēia lā, i ana ʻia ma nā watt-hola (Wh). He kuhi maʻalahi:

ʻO ka Wh i kēlā me kēia lā ≈ Watts Panel × Nā hola Lā Kiʻekiʻe × Ka pono o ka ʻōnaehana

ʻO ka pono maʻamau o ka ʻōnaehana (mea hoʻokele + kaula + pohō hoʻololi) no ka lā lawe lima pinepine pinepine70–85%.

Nā hiʻohiʻona hoʻohālike no kahi Module Solar Foldable 120W:

• Lā kauwela maikaʻi (5 mau hola lā kiʻekiʻe):
  120W × 5h × 0.8 ≈480Wh/lā
• Nā kūlana awelika (3.5 mau hola lā kiʻekiʻe):
  120W × 3.5h × 0.8 ≈336Wh/lā
• Kau ao/poʻohiwi (2 hola lā kiʻekiʻe):
  120W × 2h × 0.8 ≈192Wh/lā

No laila, i nā huakaʻi maoli he nui, e manaʻo ma kahi o200–500Wh i kēlā me kēia lāma muli o ka wahi a me ke aniau.

3) He aha ka mea hiki i kēlā mana?

Eia nā hiʻohiʻona maoli e hoʻohana ana~350Wh/lāma ke ʻano he hoʻopuka waena waena:

• Hoʻouka kelepona (10–15Wh no kēlā me kēia hoʻouka piha):~20–30 mau uku
• Papa (25–35Wh):~10–14 mau uku
• Kamepiula lawe lima (50–80Wh):~4–6 mau uku
• Pahu hau compressor 12V (maʻamau 300–700Wh/lā ma muli o ka wela a me ke kaʻina hana):
  Hiki i kahi panela 120W ke uhiʻāpanao ka hoʻohana ʻana i kēlā me kēia lā, a hiki ke uhi piha iā ia i ke aniau mālie me ka lā maikaʻi—ʻoiai inā i hui pū ʻia me ka waihona pila kūpono.

No nā mīkini AC, e hoʻomanaʻo i ka hoʻohui ʻana o ka inverter i nā pohō. ʻO ka holo ʻana i kahi hāmeʻa 60W no 5 mau hola he300Wh, akā e hoʻolālā kokoke i330–360Whma hope o ka hana pono ʻole o ka inverter.

4) No ke aha e hana pinepine ai nā Modula Foldable ma mua o nā Panel Rigid

A Modula Lā Hiki ke Pelu ʻia 120Wua kūkulu ʻia no ka lawe lima ʻana, ʻaʻole no ka hemolele ma luna o ka hale. Nā hiʻohiʻona pili i ka hana koʻikoʻi e nānā ai:

• Nā pūnaewele hana kiʻekiʻe:hoʻohana ka nui o nā panela lawe lima premium i nā mono cell a puni20–23%ka pono, kahi e kōkua ai i ka ʻilikai i kaupalena ʻia.
• ʻAno mea hoʻokele: MPPTʻohi pinepine i ka ikehu ma mua o PWM, pinepineLoaʻa 10–25%i ke aniau anuanu a i ʻole ke kiʻekiʻe loa o ka voltage o ka panela ma mua o ka voltage o ka pila.
• Nā kū hoʻopaʻa / hoʻoponopono kihi:hiki i ka kuhikuhi ʻana i ka panela ke hoʻomaikaʻi maʻalahi i ka hopena ma o20–40%e kūʻē i ke kau ʻana iā ia palahalaha.
• Ka hoʻomanawanui o ka malu:hiki i ka malu hapa ke hōʻemi nui i ka mana. Hiki i nā panela me ka hoʻonohonoho kaula noʻonoʻo ke kala aku, akā he kūleʻa nui ka malu.

5) Papa Inoa Kūʻai wikiwiki

No ke kūkulu ʻana i kahi hoʻolālā kūʻai hilinaʻi:

• E koho i ka ʻaoʻao hoʻopuka kūpono:MC4no nā mea hana uila/mea hoʻokele ikehu lā; USB-C PD inā ʻoe e hoʻopiʻi pololei i nā hāmeʻa.
• E hoʻohana i nā kaula pōkole a mānoanoa e hōʻemi i ka hāʻule ʻana o ke volta (ʻoi aku hoʻi ma nā panela 12–20V).
• E hoʻohui me kahi pila: he wā pōkole ka lā; ʻo ka mālama ʻana he mea hiki ke hoʻohana ʻia.
• E hoʻonohonoho i ke kihi a me ke kau ʻana: e mālama i ka malu ʻole a kuhikuhi hou iā ia 2-3 mau manawa i ka lā no ka loaʻa ʻana o ka hua maikaʻi loa.

Ka Laina Lalo

Hiki i kahi panela solar 120W ke hana i nāa hiki i 120Wma nā kūlana kūpono, akā pono ka hapa nui o nā mea hoʻohana e manaʻo70–100Wi ka wā o ka lā ikaika a ma kahi o200–500Wh i kēlā me kēia lāma muli o nā hola lā kiʻekiʻe a me nā pohō ʻōnaehana. Inā ʻoe e haʻi mai iaʻu i kou wahi/kau, nā mea āu e makemake ai e holo (pahu hau, kamepiula lawe lima, kumu hoʻohālike kikowaena mana), a inā ʻoe e hoʻohana iā MPPT, hiki iaʻu ke kuhi pololei i kou ikehu i kēlā me kēia lā a paipai inā lawa ka 120W a inā paha e pono ʻoe e hoʻonui i ka nui.
