Ukuba indlu inophahla lwesamente, ijonge empuma ukuya entshona okanye entshona ukuya empuma.Ngaba iiphaneli zelanga zicwangciswe zijonge emazantsi, okanye ngokwendawo yendlu?

Ukulungelelaniswa ngokwendlela yokuqhelaniswa nendlu ngokuqinisekileyo buhle ngakumbi, kodwa kukho umahluko othile kwisizukulwana samandla ukusuka kwilungiselelo elijonge ngasezantsi.Ungakanani umahluko othile wokuvelisa amandla?Sihlalutya kwaye siphendule lo mbuzo.

01

Isishwankathelo seProjekthi

Ukuthatha isiXeko saseJinan, kwiPhondo laseShandong njengesalathiso, isixa sonyaka semitha yi-1338.5kWh/m²

Thatha uphahla lwesamente yendlu njengomzekelo, uphahla luhlala ngasentshonalanga ukuya empuma, i-48pcs ye-450Wp iimodyuli ze-photovoltaic zingafakwa, kunye nomthamo opheleleyo we-21.6kWp, usebenzisa i-GoodWe GW20KT-DT inverter, iimodyuli zepv zifakwe ngasezantsi. , kunye ne-angle yokuthambekela yi-30 °, njengoko kuboniswe kumzobo ongezantsi.Umahluko kumbane wokuvelisa kwi-30°/45°/60°/90° kumzantsi ngempuma kunye ne-30°/45°/60°/90° kumzantsi ngentshona ulinganisiwe ngokulandelelanayo.

02

I-Azimuth kunye ne-Irradiance

I-angle ye-azimuth ibhekisela kwi-angle phakathi kwe-orientation ye-photovoltaic array kunye ne-direct direction esezantsi (kungakhathaliseki ukuba i-declination magnetic).Ii-angles ze-azimuth ezahlukeneyo zihambelana nezixa ezahlukeneyo zemitha efunyenweyo.Ngokwesiqhelo, uluhlu lwephaneli yelanga lujongiswe kwicala lokuqhelaniswa nelona xesha lide lokuvezwa.i-angle njengeyona azimuth ilungileyo.

Nge-angle yokuthambekela esisigxina kunye nee-angles ze-azimuth ezahlukeneyo, i-radiation eyongezelelweyo yonyaka yesikhululo samandla.

Cukuqukwa:

• Ngokunyuka kwe-angle ye-azimuth, i-irradiance iyancipha ngokulandelelana, kwaye i-irradiance ngenxa yezantsi iyona inkulu.

• Kwimeko ye-angle ye-azimuth efanayo phakathi komzantsi-ntshona kunye nomzantsi-mpuma, kukho umehluko omncinci kwixabiso le-irradiance.

I-Azimuth kunye ne-inter-array shadows

(1) Ngenxa yoyilo lwesithuba esisemazantsi

Umgaqo oqhelekileyo wokumisela isithuba se-array kukuba i-photovoltaic array akufanele ivalwe ngexesha lexesha ukusuka kwi-9: 00 ukuya kwi-15: 00 ntambama kwi-solstice yasebusika.Kubalwa ngokwefomula ilandelayo, umgama othe nkqo phakathi komgama phakathi koluhlu lwe-photovoltaic okanye indawo yokuhlala enokwenzeka kunye nomda ongezantsi woluhlu akufanele ube ngaphantsi kwe-D.

Kubalwe D≥5 m

(2) Ukulahleka komthunzi kwii-azimuth ezahlukeneyo (ukuthatha umzantsi ngempuma njengomzekelo)

Kwi-30 ° empuma ukuya ngasemazantsi, kubalwa ukuba ilahleko yokuvala ithunzi ngaphambili nangasemva kwenkqubo kwi-solstice yasebusika yi-1.8%.

Kwi-45 ° empuma ukuya ngasemzantsi, kubalwa ukuba ilahleko yokuvala ithunzi ngaphambili nangasemva kwenkqubo kwi-solstice yasebusika yi-2.4%.

Kwi-60 ° empuma ukuya ngasemazantsi, kubalwa ukuba ilahleko yokuvala ithunzi ngaphambili nangasemva kwenkqubo kwi-solstice yasebusika yi-2.5%.

Kwi-90 ° empuma ukuya ngasemazantsi, kubalwa ukuba ilahleko yokuvala ithunzi ngaphambili nangasemva kwenkqubo kwi-solstice yasebusika yi-1.2%.

Ngaxeshanye ukulinganisa ii-engile ezine ukusuka emzantsi ukuya entshona ufumana le grafu ilandelayo:

Isiphelo:

Ukulahlekelwa kwe-shading ye-front and back arrays ayibonisi ubudlelwane bomgca kunye ne-azimuth angle.Xa i-angle ye-azimuth ifikelela kwi-angle ye-60 °, ilahleko ye-shading ye-front and back arrays iyancipha.

Ukulinganisa ukulinganisa ukuveliswa kwamandla

Kubalwa ngokomthamo ofakiweyo we-21.6kW, usebenzisa amaqhekeza angama-48 eemodyuli ezingama-450W, umtya we-16pcsx3, usebenzisa i-inverter eyi-20kW

Ukulinganisa kubalwa kusetyenziswa i-PVsyst, ukuguquguquka kuphela yi-angle ye-azimuth, abanye bahlala bengatshintshi:

Isiphelo:

• Njengoko i-angle ye-azimuth ikhula, ukuveliswa kwamandla kuyancipha, kwaye ukuveliswa kwamandla kwi-0 degrees (ngenxa yezantsi) kukhulu.
• Kwimeko ye-angle ye-azimuth efanayo phakathi komzantsi-ntshona kunye nomzantsi-mpuma, kukho umehluko omncinci kwixabiso lokuvelisa amandla.
• Ngokuhambelana nentsingiselo yexabiso le-irradiance

Ukuqukumbela

Enyanisweni, ukucinga ukuba i-azimuth yendlu ayihambelani ne-orientation yasezantsi, indlela yokulinganisa ukuveliswa kwamandla kunye ne-aesthetics yokudibanisa isikhululo samandla kunye nendlu kufuneka iqulunqwe ngokweemfuno zayo.
