Pūrere tiaki ngaru rā mono hei tiaki i te pūnaha rā, i te kaitahuri panui rā rānei
He mea nui ngā Pūrere Ārai Ngaru (SPD) hei tiaki i ngā kaitahuri hiko photovoltaic (PV) o te rā mai i ngā ngaru hiko me ngā titaha, inā koa ko ērā e puta mai ana i te uira. I ngā wāhi he nui te mahi a te uira, ka pāngia pea ngā pūnaha PV kāore i tiakina e te kino maha me te kino, ka arahi ki ngā utu whakatikatika nui, te roa o te wā kore mahi, me te ngaronga o ngā moni whiwhi. He mea nui ngā SPD kua tāuta tika hei whakaiti i te pānga o ngā whiunga uira me te tiaki i ngā wāhanga tairongo o ngā pūnaha PV, tae atu ki ngā kaitahuri AC/DC, ngā taputapu aroturuki, me ngā rarangi PV. Mā te haumi ki te tiaki ngaru whai hua, ka taea e koe te whakarite i te roa me te pono o tō pūnaha pūngao rā.
Me pēhea te whiriwhiri i te taputapu tiaki ngaru tika mō tō tono motuhake?
He mea nui te whiriwhiri i te taputapu tiaki ngaru tika (SPD) mō tō tono. Tīmata mā te tautuhi i te momo SPD e hiahiatia ana e koe. He pai te mahi a ngā taputapu T1 i roto i ngā taiao morearea, pērā i ngā wāhi e pāngia ana e te uira tika. He mea noa ēnei i roto i ngā whare ahumahi, i ngā pūnaha photovoltaic rānei. Ka whakamahia ngā taputapu T2 i roto i te whare hei whakahaere i ngā ngaru kore tika, ko ngā taputapu T3 ia e whakarato ana i te tiakitanga tāpiri mō ngā hiko tairongo.
Tirohia te whakatauranga ngaohiko kia tino ōrite ki tō pūnaha. Mō ngā pūnaha DC pērā i ngā tatūnga photovoltaic, he mea nui te whiriwhiri i tētahi taputapu me te ngaohiko tika. Me whakarite hoki ka taea e te kaha tukunga te whakahaere i ngā taumata ngaru e tumanakohia ana. I ngā wāhi morearea nui, he mea nui te kaha teitei ake. Kaua hoki e wareware ki te wā urupare—he mea nui te urupare tere hei tiaki i ngā taputapu tairongo mai i ngā pikinga ngaohiko.
Whakaarohia te taiao e tāutahia ai te SPD. Mena kei roto i ngā āhuatanga kino, whiriwhiria he hoahoa ātete huarere, ātete mura rānei. Mō ngā tono nui, ka whakaratohia e ngā SPD me te aroturuki mamao ngā whakahoutanga mahi wā-tūturu, hei āwhina i te tiaki me te whakakapinga. Hei whakamutunga, kia tino tutuki te SPD i ngā paerewa ahumahi pēnei i te IEC 61643, ā, kei a ia ngā tiwhikete pēnei i te ISO, te CE rānei.
Ka tutuki i ngā SPD o tā mātou wheketere ngā āhuatanga matua katoa e tika ana mō te tiaki pono. Mā te whiriwhiri i ā mātou taputapu tiaki ngaru, ka whakarite koe i te tiakitanga tino pai me te pono mō te wā roa mō ō taputapu.
Me pēhea te whakapai ake i te tiaki ārai ngaru hiko e ngā āheinga aroturuki mamao?
Mā tēnei ka taea te kite wawe i ngā raruraru pea, ka taea ai te tiaki wawe i mua i te puta o ngā hapa. Mā te tautuhi i ngā raruraru i mua i te wā, ka taea e ngā pakihi te whakarite i ngā tirotiro me ngā whakakapinga i te wā tika, ka whakaiti i te mōrearea o te wā kore mahi, te kino rānei o ngā taputapu. Ka whakaitihia hoki e ngā whakatūpato tere ngā aukatinga pūnaha, inā koa i roto i ngā hanganga nui pēnei i ngā pūnaha photovoltaic me ngā whare ahumahi, i ngā wāhi ka puta he mate pūtea nui nā te aukatinga hiko.
Hei tāpiritanga, ka whakaitihia e te aroturuki mamao ngā utu mahi me te tiaki mā te whakakore i ngā tirotiro koretake i te papaanga, me te whakarite kia pai te mahi a ngā taputapu tiaki ngaru. Mō ngā whakaurunga nui ake, ka whakangawarihia te tukanga e te whakahaere pokapū o ngā taputapu maha puta noa i ngā wāhi rerekē, ka whakarite kia pono me te tere o te urupare ki ngā take.
