E nānā i kēia alakaʻi no ke aʻo ʻana pehea e hoʻokō ai nā cell solar i kāu ʻōnaehana solar, a me ke aʻo ʻana e pili ana i ke kumukūʻai, nā ʻano pākaukau a me nā mea hou aku.
Hiki i ka panela lā ke ho'ōla iā ʻoe i nā kaukani kālā i nā bila ikehu i kona wā e ola ana, akā e hoʻoulu wale kāu mau panela i ka uila i ka lā.Hoʻopau nā panela solar i kēia palena ma o ka hāʻawi ʻana i kahi ʻōnaehana mālama ikehu hiki iā ʻoe ke hilinaʻi i nā lā ao a me ka pō.
ʻO nā panela solar off-grid kahi hoʻopukapuka maikaʻi loa, akā hiki i nā ʻeke pākaukau ke hoʻomaikaʻi i kā lākou hana.Ma kēia ʻatikala, wehewehe mākou ma ka hui Guides Home i nā mea āpau e pono ai ʻoe e ʻike e pili ana i nā panela lā, me nā ʻano like ʻole a me ke ʻano o ka hana ʻana, ke kumukūʻai, a pehea e koho ai i kahi pākaukau no kāu ʻōnaehana solar.
ʻO ka panela lā he mea ia e mālama ai i ka hoʻoili uila ma ke ʻano kemika, a hiki iā ʻoe ke hoʻohana i kēia ikehu i kēlā me kēia manawa, ʻoiai inā ʻaʻole hoʻohua ka uila i kāu panela lā.ʻOiai i ʻōlelo pinepine ʻia ʻo ia me nā pūnaewele solar i hui pū ʻia me nā panela solar, hiki i nā ʻōnaehana pākaukau hoʻihoʻi ke mālama i ka uku mai kekahi kumu.'O ia ho'i, hiki iā 'oe ke ho'ohana i ka mānoanoa e ho'opa'a i kou mau 'a'a i ka wā 'a'ole e hana ana kāu mau panela lā, a i 'ole hiki iā 'oe ke ho'ohana i nā kumu ikehu hou e like me nā turbine makani.
Aia nā ʻano like ʻole o nā kemika pākaukau, kēlā me kēia me kona pono ponoʻī a me nā palena.ʻO kekahi mauʻano o nā pila he kūpono no nā noi e pono ai ke hāʻawi i ka mana nui no ka manawa pōkole, aʻo nā mea'ē aʻe e kūpono i nā noi e koi ana i ka mana paʻa no ka manawa lōʻihi.ʻO kekahi mau kemika maʻamau i hoʻohana ʻia i loko o nā pūnaewele solar e komo pū me ka waikawa lead, lithium ion, nickel cadmium, a me redox fluxes.
I ka hoʻohālikelike ʻana i nā pūnaewele lā, pono e noʻonoʻo ʻia nā mana mana (kilowatt a i ʻole kW) a me ka hiki ke mālama i ka ikehu (kilowatt hola a i ʻole kWh).Hōʻike ka helu mana iā ʻoe i ka nui o ka ukana uila e hiki ke hoʻopili ʻia i ka pākaukau, a ʻo ka hiki ke mālama iā ʻoe i ka nui o ka mana e hiki ke paʻa i ka pā.No ka laʻana, inā he 5 kW ka mana o ka solar cell a me ka hiki ke mālama i 10 kWh, hiki ke manaʻo ʻia:
Pono e hoʻomaopopo ʻia ʻaʻole i hoʻolālā ʻia nā panela solar a me nā ʻōnaehana mālama pākaukau no ka mana like.No ka laʻana, loaʻa paha iā ʻoe kahi ʻōnaehana solar home 10 kW me kahi pākaukau 5 kW a me kahi pākaukau 12 kWh.
Ma muli o ka nui a me nā mea ʻē aʻe e like me kou wahi, hiki iā ʻoe ke uku ma waena o $25,000 a me $35,000 no ka ʻōnaehana solar a me nā ʻāpana, e like me ka US Energy Efficiency and Renewable Energy Administration.ʻOi aku ka maʻalahi (a maʻalahi hoʻi) ke hoʻokomo ʻana i nā panela lā a me nā pila i ka manawa like – inā koho ʻoe e kūʻai i kahi waiho ma hope o ka hoʻokomo ʻia ʻana o nā panela lā, hiki ke kūʻai ʻia nā pila ma waena o $12,000 a me $22,000.
Ma ke ʻano o ka hana, ua manaʻo ʻia nā pā lithium-ion i koho maikaʻi loa no nā noi hale e koi ana i ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i kēlā me kēia lā.
Mahalo i ke Inflation Reduction Act i hoʻoholo ʻia ma ʻAukake 2022, hiki i nā panela solar ke loaʻa i kahi hōʻaiʻē ʻauhau federal 30%.ʻO kēia ka hōʻaiʻē ʻauhau kālā federal hiki iā ʻoe ke loaʻa no ka makahiki āu i kūʻai ai i kāu ʻōnaehana solar.No ka laʻana, inā kūʻai ʻoe i nā waiwai he $10,000, hiki iā ʻoe ke koi i kahi hōʻemi ʻauhau $3,000.ʻOiai hiki iā ʻoe ke noi no kahi hōʻaiʻē hoʻokahi wale nō, inā ʻaiʻē ʻoe i ka ʻauhau ma mua o kāu hōʻaiʻē, hiki iā ʻoe ke ʻōwili iā ia i ka makahiki e hiki mai ana.
Hōʻike ka papa ma lalo nei i nā hiʻohiʻona nui o nā pūnaewele solar maʻamau, a me ke kumukūʻai maʻamau o kēlā me kēia ma nā noi noho.
Hoʻopuka ka National Renewable Energy Laboratory (NREL) i nā hōʻike i kēlā me kēia manawa e loaʻa ana ka ʻikepili kumu kūʻai hou loa no ka lā a me nā ʻōnaehana pākaukau ma nā hale noho, ʻoihana a me nā papahana grid.Mālama ʻo Pacific Northwest National Laboratory (PNNL) i kahi waihona like e uhi ana i kekahi mau ʻenehana pākaukau ma nā noi megawatt (ma luna o 1000 kW).
Loaʻa i nā pūnaewele solar ka hana maʻamau like, akā kūpono kēlā me kēia ʻano no nā noi like ʻole.Ke kūpono ka kemika o kāu mau pūnaewele lā no kahi noi kikoʻī, e hāʻawi ana kāu mau pūniu lā i ka hilinaʻi kiʻekiʻe aʻe a hoʻihoʻi i ka hoʻopukapuka.
No ka laʻana, uku kekahi mau mea kūʻai uila i nā kumukūʻai kiʻekiʻe i kēlā me kēia kilowatt-hola i kekahi mau manawa o ka lā a i ʻole e uku hou aku no ka piʻi ʻana o ka uila.I kēia hihia, pono ʻoe i kahi pākaukau e hiki ke hāʻawi i ka mana nui no kahi manawa pōkole.He kūpono nā ʻenekini Lithium-ion no kēia hana, akā ʻaʻole pono nā pihi kahe redox.
Ma waho o ke ʻano o ka pākaukau, pono ʻoe e noʻonoʻo i ka hohonu o ka hoʻokuʻu ʻana (DoD), e hōʻike ana i ka hiki ke hoʻohana ʻia o ka pā.Inā ʻoi aku ka DoD, e hoʻemi nui ʻia ke ola pākaukau a hiki i kēia ke hopena i ka pōʻino mau loa.No ka laʻana, ʻae ʻia no ka cell solar me 80% DoD e hoʻohana i 70% o ka ikehu i mālama ʻia, akā ʻaʻole no ka cell w.
