Pehea ka lōʻihi o ka noho ʻana o nā mea hoʻohuli lā?

Ma ka hapa mua o kēia moʻo, ua nānā ka makasina pv i kahuahua ola o ka solar panels, he mea hiki ke paa. Ma kēia ʻāpana, nānā mākou i nā mea hoʻohuli solar hale i ko lākou mau ʻano like ʻole, pehea ka lōʻihi o lākou, a pehea ke kūpaʻa.

ʻO ka inverter, kahi mea e hoʻohuli ai i ka mana DC i hana ʻia e nā panela lā i ka mana AC hiki ke hoʻohana ʻia, hiki ke hele mai i kekahi mau hoʻonohonoho like ʻole.

ʻO nā ʻano mea nui ʻelua o nā inverters i nā noi noho he string inverters a me microinverters. I kekahi mau noi, ua hoʻolako ʻia nā mea hoʻohuli kaula me nā module-level power electronics (MLPE) i kapa ʻia ʻo DC optimizers. Hoʻohana maʻamau nā Microinverters a me DC optimizers no nā hale me nā kūlana pale a i ʻole ka hoʻonohonoho sub-optimal (ʻaʻole i ke alo hema).

Ma nā noi i loaʻa i ka hale kahi azimuth maikaʻi (ka hoʻonohonoho ʻana i ka lā) a me nā pilikia ʻole o ka pale ʻana, hiki i kahi mea hoʻohuli kaula ke lilo i mea hoʻonā maikaʻi.

Hele mai nā string inverters me nā wili maʻalahi a me kahi wahi kikowaena no ka hoʻoponopono maʻalahi e nā ʻenehana solar.ʻO ka mea maʻamau, emi ke kumukūʻai,wahi a Solar Reviews. Hiki i nā Inverters ke kūʻai maʻamau i ka 10-20% o ka nui o ka hoʻonohonoho ʻana o ka panel solar, no laila he mea nui ke koho ʻana i ka mea kūpono.

Pehea ka lōʻihi o lākou?

ʻOiai hiki i nā panela lā ke lōʻihi i 25 a 30 mau makahiki a ʻoi aku paha, ʻoi aku ka pōkole o ke ola o nā mea hoʻohuli, ma muli o nā mea ʻelemakule wikiwiki. ʻO kahi kumu maʻamau o ka hāʻule ʻole i nā inverters ʻo ia ka lole electro-mechanical ma ka capacitor i ka inverter. ʻOi aku ka pōkole o nā capacitors electrolyte a ʻoi aku ka wikiwiki o ka makahiki ma mua o nā mea maloʻo.wahi a Solar Harmonics.

Ua ʻōlelo ʻo EnergySageʻO kahi typical centralized residential string inverter e mau ma kahi o 10-15 mau makahiki, a no laila pono e hoʻololi ʻia i kekahi manawa i ke ola o nā panels.

Nā mea hoʻohuli aholoaʻa maʻamaunā palapala hōʻoia maʻamau mai 5-10 mau makahiki, he nui me ke koho e hoʻonui i 20 mau makahiki. ʻO kekahi mau ʻaelike solar ka mālama manuahi a me ka nānā ʻana ma o ka manawa o ka ʻaelike, no laila he mea naʻauao e loiloi i kēia ke koho ʻana i nā inverters.

ʻOi aku ka lōʻihi o ke ola o nā Microinverters, ua ʻōlelo ʻo EnergySage hiki iā lākou ke hoʻomau pinepine i 25 mau makahiki, kokoke i ka lōʻihi o ko lākou mau hoa panel. Ua ʻōlelo ʻo Roth Capital Partners e hōʻike pinepine ana kāna mau pilina ʻoihana i nā hemahema microinverter ma kahi haʻahaʻa haʻahaʻa ma mua o nā string inverters, ʻoiai ʻoi aku ka kiʻekiʻe o ke kumu kūʻai mua i nā microinverters.

Loaʻa i nā Microinverters kahi palapala hōʻoia maʻamau 20 a 25 mau makahiki. Pono e hoʻomaopopo ʻia ʻoiai ʻo ka microinverters he palapala hōʻoia lōʻihi, he ʻenehana hou lākou mai nā makahiki he ʻumi i hala aku nei, a ke ʻike ʻia inā e hoʻokō nā mea hana i kāna ʻōlelo hoʻohiki 20+ makahiki.

Pela no ka DC optimizers, ka mea maʻamau i hui pū ʻia me ka inverter string centralized. Hoʻolālā ʻia kēia mau ʻāpana no 20-25 mau makahiki a loaʻa iā ia kahi palapala hōʻoia e hoʻohālikelike i kēlā manawa.

No nā mea hoʻolako inverter, paʻa kekahi mau hōʻailona i ka māhele mākeke. Ma ʻAmelika Hui Pū ʻIa, Enphase ke alakaʻi mākeke no nā microinverters, ʻoiai ke alakaʻi nei ʻo SolarEdge i nā inverters string. Ke hana nei ʻo Tesla i nā nalu i loko o ke keʻena inverter string noho, e lawe ana i ka māhele mākeke, ʻoiai ke ʻike ʻia nei ka nui o ka hopena o ke komo ʻana o ka mākeke o Tesla, wahi a kahi moʻolelo ʻoihana mai Roth Capital Partners.

(Heluhelu: “Hoʻopaʻa inoa nā mea hoʻonoho lā o US i nā Qcells, Enphase ma ke ʻano he mau hōʻailona kiʻekiʻe“)

Nā hāʻule

Ua ʻike ʻia kahi noiʻi ʻana e kWh Analytics he 80% o nā hemahema o ka lā ma ka pae inverter. Nui nā kumu o kēia.

Wahi a Fallon Solutions, hoʻokahi kumu ʻo ka hewa grid. Hiki ke ho'ōki i ka hana ʻana o ka mea hoʻohuli a i ʻole ka haʻahaʻa ma muli o ka hewa grid, a hiki ke hoʻāla ʻia nā mea hoʻokele kaapuni a i ʻole fuses no ka pale ʻana i ka inverter mai ka hāʻule ʻana o ka uila kiʻekiʻe.

I kekahi manawa hiki ke hoʻokō ʻia i ka pae MLPE, kahi e hōʻike ʻia ai nā ʻāpana o ka mana optimizers i nā wela kiʻekiʻe ma luna o ka hale. Inā ʻike ʻia ka hoʻemi ʻana o ka hana, he hewa paha ia i ka MLPE.

Pono e hana pono ʻia ke kau ʻana. E like me ke kānāwai o ka manamana nui, ua ʻōlelo ʻo Fallon e piʻi ka mana o ka panel solar i 133% o ka mana inverter. Inā ʻaʻole i hoʻohālikelike pono ʻia nā panela i kahi mea hoʻohuli kūpono, ʻaʻole lākou e hana maikaʻi.

Ka malama ana

No ka mālama pono ʻana i kahi inverter no ka manawa lōʻihi, ʻo iapaipai ʻiae hoʻokomo i ka mea hana ma kahi maloʻo a maloʻo me ka nui o ka ea hou. Pono nā mea hoʻokomo e pale i nā wahi me ka mālamalama o ka lā, ʻoiai ua hoʻolālā ʻia nā hōʻailona kikoʻī o nā mea hoʻohuli waho e pale aku i ka lā ma mua o nā mea ʻē aʻe. A, i ka nui-inverter hoʻonoho, he mea nui e hōʻoiaʻiʻo aia i ka pono hoʻomaʻemaʻe ma waena o kēlā me kēia inverter, no laila, ʻaʻohe wela ma waena o nā inverters.

He hana maikaʻi loa ka nānā ʻana i waho o ka inverter (inā hiki ke loaʻa) i kēlā me kēia hapaha makahiki, e hōʻoia ʻaʻole ʻaʻohe hōʻailona kino o ka pōʻino, a ʻaʻohe lepo a me ka lepo nā puka makani a me nā ʻili hoʻomaha.

Manaʻo ʻia hoʻi e hoʻonohonoho i kahi nānā ʻana ma o kahi mea hoʻonohonoho solar laikini i kēlā me kēia ʻelima makahiki. He $200-$300 ke kumu kūʻai o ka nānā ʻana, ʻoiai ua loaʻa i kekahi mau ʻaelike solar ka mālama manuahi a me ka nānā ʻana no 20-25 mau makahiki. I ka wā o ka nānā ʻana, pono e nānā ka mea nānā i loko o ka inverter no nā hōʻailona o ka corrosion, pōʻino, a i ʻole nā ​​​​pests.
