2. No. No. na bangarorin hasken rana a cikin jerin abubuwa:
A lokacin da bangarorin hasken rana suna wired a cikin jerin kirtani (wannan shine tabbataccen ɓangaren guda ɗaya da mummunan kwamitin na gaba), ƙarfin lantarki na kowane panel da aka ƙara tare don ba da jimlar igiyar wutar lantarki. Saboda haka muna buƙatar sanin adadin sassan hasken rana da kuka yi niyyar waya a cikin jerin.
Lokacin da kuke da duk bayanan da kuka shirya don shigar da shi cikin waɗannan garken hasken rana masu zuwa da lissafin Sizing na yanzu don ganin ko ƙirar Panel na yanzu zai dace da bukatun ku.

3. Misali:
Curitiba, Birnin Brazil, abokin ciniki a shirye yake don shigar da wutar Renac guda 5kW, Matsakaicin zafin rana na birni shine 160VPLETHETER RANA NE 160VETH, IN90VERPLOTGAGEERE NE -3 1000v.
Inverter da datatset:
SOLAR Panel ditheet:
A) Sizing Voltage
A mafi ƙasƙanci zazzabi (wurin dogara, anan -3 ℃), bude-masauki vc na many a cikin kowane igiyar dole ne ya wuce iyakar shigarwar injin (1000 v):
1) lissafin bude ido a -3 ℃:
Voc (-3 ℃) = 45.5 * (1 + (- 3-25) * (- 0.33%) = 49.7 volt
2) lissafin n matsakaicin adadin kayayyaki a cikin kowane kirtani:
N = max shigar da wutar lantarki (1000 v) /49.7 volt = 20.12 (koyaushe kewaye)
Yawan bangarorin PV a cikin kowane zaren dole ne ya wuce kayayyaki 20 baicin, a kan mafi girman zafin jiki (a nan kuma MPP voltage ta kasance a cikin kewayen MPL Power (160v-950v):
3) lissafin matsakaicin ƙarfin wutar lantarki VMPP a 35 ℃:
Vmpp (35 ℃) = 45.5 * (1+ (35-25) * (- 0.33%) = 44 volt
4) lissafin mafi karancin adadin medules m a kowane kirtani:
M = min mPpp voltage (160 v) / 44 vPT = 3.64 (koyaushe yana zagaye)
Yawan bangarorin kwallon kafa na rana a kowane igiyar dole ne su kasance aƙalla 4.
B) Sizing na yanzu
A takaice Circuit na yanzu na sc na PV ɗin dole ne ya wuce mafi ƙarancin shigarwar yanayin da Inverter Ikler:
1) lissafin matsakaicin halin yanzu a 35 ℃:
Isc (35 ℃) = ((1+ (10+ (TCSC / 100)) * ISC) * ISC) = 9.22 (1) (0+ (0)) = 9.1.06%)) = 9.10)
2) lissafin p matsakaicin adadin kirtani:
P = mafi girman shigarwar yanzu (12,9A) /9.16 a = 1.36 kirji (koyaushe ƙasa)
PV da PV dole ne ya wuce kirtani ɗaya.
Sha'awar:
Ba a buƙatar wannan matakin don inverter mpp da kirtani ɗaya kawai.
C) Kammalawa:
1zaren daya, wanda aka haɗa da mai lamba uku na 5kW.
2A tsakanin meduka 4-20.
Sha'awar:
Tun da kyau mafi kyawun ƙwayoyin injiniya uku yana kusa da 630v (mafi kyawun daskararren ƙwayoyin injiniya na kusan 360v), ingantaccen aiki na inverter shine mafi girma a wannan lokacin. Don haka ana bada shawarar yin lissafin adadin kayayyakin hasken rana bisa ga mafi kyawun ƙwayoyin sanyi:
N = mafi kyau mppt voc / voc (-3 ° C) = 756v / 49.7v = 15.21
Single Crystal Panel kyau mafi kyau m mpp = mafi kyau mppt Voltage x 1.2 = 630 × 1.2 = 756v
Polycrystal Panel ya fi dacewa da MPP
Don haka ga Renac uku na R3-5k-DT da aka ba da shawarar hasken rana na rana 16x330W = 5280W = 5280w.
4. Kammalawa
Inverter shigar da bangarorin hasken rana ya dogara da yawan dabbobi da zazzabi mai inganci. Mafi kyawun aikin ya dogara ne akan mafi kyawun MPP wutan lantarki.
