ʻO nā ʻano nui ʻekolu o nā ʻōnaehana mana solar: On-Grid, Off-Grid a me Hybrid

ʻO nā ʻano nui ʻekolu o nā ʻōnaehana mana lā

1. On-grid - ʻike ʻia hoʻi he grid-tie a grid-feed solar system

2. Off-grid - ʻike ʻia hoʻi he ʻōnaehana mana kū hoʻokahi (SAPS)

3. Huinaʻi - ʻōnaehana solar pili i ka grid me ka waiho ʻana i nā pākaukau

Nā Mea Nui o ka Pūnaehana Lā

Nā Panela Lā

ʻO ka hapa nui o nā panela lā o kēia wā he nui nā kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻekiʻe. ka mea e hoʻoulu ai i ka uila o ke au pololei (DC) mai ka lā. ʻO nā panela lā, ʻike ʻia hoʻi ʻo nā modula lā, ua hoʻopili maʻamau ʻia i loko o 'nā kaula' no ka hana ʻana i ka mea i ʻike ʻia he ʻano lā. ʻO ka nui o ka ikehu o ka lā i hana ʻia ma muli o nā kumu he nui, ʻo ia hoʻi ka hoʻonohonoho ʻana a me ke kihi kihi o nā panela solar, ka pono o ka panela solar, a me nā poho ma muli o ka malu, ka lepo a me ka wela ambient.

Hiki i nā panela o ka lā ke hoʻoulu i ka ikehu i ka wā ʻohu a me ka pōʻeleʻele, akā pili ka nui o ka ikehu i ka 'mānoanoa' a me ke kiʻekiʻe o nā ao, kahi e hoʻoholo ai i ka nui o ka mālamalama e hiki ke hele. ʻO ka nui o ka ikehu māmā ʻike ʻia ʻo ia ka lā irradiation a maʻa mau ʻia i ka lā holoʻokoʻa me ka hoʻohana ʻana i ka huaʻōlelo Peak Sun Hours (PSH). ʻO ka PSH a i ʻole ka awelika o nā hola o ka lā o kēlā me kēia lā e hilinaʻi nui ʻia i ka wahi a me ka manawa o ka makahiki.

Mea hoʻohuli lā

Hoʻopuka nā panela i ka uila DC, pono e hoʻololi ʻia i ka uila alternating current (AC) no ka hoʻohana ʻana i ko mākou mau home a me nā ʻoihana. ʻO kēia ke kuleana nui o ka mea hoʻohuli lā. I loko o kahi 'string' inverter nenoaiu, ua hoʻopili pū ʻia nā panela lā i ka moʻo, a lawe ʻia ka uila DC i ka inverter, kahi e hoʻohuli ai i ka mana DC i ka mana AC. Ma kahi ʻōnaehana microinverter, loaʻa i kēlā me kēia panel kona micro-inverter i hoʻopili ʻia ma ka ʻaoʻao hope o ka panel. Hoʻopuka mau ka panel i ka DC akā ua hoʻololi ʻia i AC ma luna o ka hale a hānai pololei ʻia i ka papa hoʻololi uila.

Aia kekahi mau ʻōnaehana hoʻohuli kaula ʻoi aku ka maikaʻi e hoʻohana ana i nā mea hoʻopono mana liʻiliʻi i hoʻopili ʻia ma hope o kēlā me kēia panel solar 

ʻO nā ʻanuʻu

Loaʻa nā ʻuala i hoʻohana ʻia no ka mālama ʻana i ka ikehu lā i ʻelua ʻano nui: kēpau-ʻakika (AGM & Gel) a me ka lithium-ion. Loaʻa kekahi mau ʻano ʻē aʻe, e like me ka redox flow batteries a me ka sodium-ion, akā e nānā mākou i nā mea maʻamau ʻelua. ʻO ka hapa nui o nā ʻōnaehana mālama ikehu hou e hoʻohana ana i nā ʻona lithium-ion rechargeable a loaʻa i nā ʻano like ʻole a me nā nui, hiki ke hoʻonohonoho ʻia ma nā ʻano he nui i wehewehe ʻia ma nā kikoʻī hou aku ma aneʻi.

Hoʻohālikelike ʻia ka nui o ka pākaukau ma ke ʻano he mau hola Amp (Ah) no ka waikawa lead a i ʻole kilowatt hola (kWh) no ka lithium-ion. Eia naʻe, ʻaʻole hiki ke hoʻohana ʻia nā mana a pau. Hiki ke hāʻawi maʻamau i nā pākaukau Lithium-ion a hiki i 90% o ko lākou hiki ke loaʻa i kēlā me kēia lā. I ka hoʻohālikelike ʻana, hāʻawi maʻamau nā pākaʻi lead-acid i ka 30% a i ka 40% o ko lākou mana piha i kēlā me kēia lā e hoʻonui i ke ola pākaukau. Hiki ke hoʻokuʻu piha ʻia nā pākaʻi lead-acid, akā pono e hana ʻia kēia i nā kūlana hoʻihoʻi pilikia.
