Nekukura kuri kuita sainzi netekinoroji nekukurumidza, tekinoroji yekugadzira magetsi emagetsi ezuva yave ichishandiswa zvakanyanya munyika nekune dzimwe nyika, mumhando dzakasiyana-siyana uye munzvimbo dzakasiyana-siyana, kunyanya kumafekitori makuru emagetsi ezuva, zvivakwa zvekugara nemabhizimisi, matenga, kubatanidzwa kwezvivakwa zvezuva, marambi emugwagwa ezuva nezvimwewo. Zvivako, mumvuri, chimney, guruva, makore, nezvimwe zvinhu zvichazopedzisira zvavhara ma solar modules munzvimbo dzakati. Nekuda kweizvozvo, vazhinji vanonetseka nezvekuti zviitiko zvakadaro zvinokanganisa sei kushanda kwemagetsi ezuva uye kuti zvingagadziriswa sei.
Mukuita, masero ezuva anowanzo umbwa nemamodule akawanda akabatana mu series kana parallel kuti abudise voltage kana current inodiwa. Kuti uwane high photovoltaic conversion efficiency, sero rega rega riri mumodule rinofanira kuva nemabasa akafanana. Munguva yekushandiswa, sero rimwe chete kana akawanda anogona kusawirirana, semuenzaniso, nekuda kwekutsemuka, kutadza kubatana kwemukati, kana mumvuri, zvichikonzera kusawirirana pakati pehunhu hwavo nehwese.
Mune mamwe mamiriro ezvinhu, module yesolar cell ine mumvuri muchikamu chebazi rakatevedzana inoshanda semutoro, ichidya simba rinogadzirwa nemamwe mamodule ezuva nechiedza. Module yesolar cell ine mumvuri ichapisa panguva ino, zvichikonzera mhedzisiro yenzvimbo inopisa. Kukanganisa uku kunogona kukonzera kukuvara kukuru kune solar cell. Masero ane mumvuri anogona kushandisa rimwe resimba rinogadzirwa nemasero ezuva ane mwenje. Kuti udzivise solar cell kuti isakuvadzwe nemhedzisiro yenzvimbo inopisa, batanidza bypass diode iri pakati penzvimbo dzakanaka nedzisina kunaka dze solar cell module. Izvi zvinodzivirira simba rinogadzirwa ne light-illuminated module kuti risapedzwe ne shading module.
Nezvezvikonzero zvinokonzera hot spot, kwakabva masero edambudziko, uye matanho ekudzivirira.
Chinhu chikuru chePV module i solar cell. Kazhinji, hunhu hwemagetsi hwe solar cells dzinoshandiswa mumodule yega yega hunofanira kunge hwakafanana; zvikasadaro, mhedzisiro inonzi hot spot ingangoitika pamasero asina kushanda zvakanaka kwemagetsi kana kuti ane mumvuri (problem cells).
Kuti risanyanya kupisa, sero rega rega rinofanira kubatanidzwa pamwe chete ne bypass diode; kana bhatiri rikakundikana kana kuti maseru akaiswa mumvuri, bypass diode ichapfuura maseru ane dambudziko.
Hazvigoneki kubatanidza diode iri pamwe chete nesero rega rega. Kazhinji, gungano rine masero gumi nemasere (36 kana 54 ari munhevedzano) kana makumi maviri nemana (masero makumi manomwe nemaviri ari munhevedzano) ari munhevedzano ne diode iri munhevedzano.
Zvinogoneka kuti kana magetsi anogadzirwa mumasero aya gumi nemasere kana makumi maviri nemana asingawirirane, kureva kuti, kana paine sero rine dambudziko, magetsi ari pamusoro petambo anokonzera nzvimbo dzinopisa pasero rine dambudziko. Kana magetsi achisiyana kubva pane tambo kuenda kune imwe, nhanho yedanho kana curve isina kujairika ichaonekwa pamodule's characteristic curve ne bypass diode yakabatana.
Kana mashandiro emasero ezuva ari mumodule asingaenderane, nzvimbo dzinopisa dzichaitika zvechokwadi. Zvinhu zvinopisa zvinogona kuonekwa uchishandisa curve yemumodule uye infrared imaging.
Kana kusashanda zvakanaka kwemasero ezuva mumodule kukakonzerwa nekurasikirwa nekushanda zvakanaka mushure mekudzikira kwechiedza chemasero ezuva, tinogona kuona dambudziko renzvimbo inopisa tichishandisa curve yemhando yemodule uye infrared imaging. Tinogona kuenzanisa curve yemhando yemodule isati yadzikira uye yapera, pamwe nekushandisa infrared imaging kuti tione kuti inochinja sei isati yadzikira uye yapera.
Kana module isina kubatana ne bypass diode, kunyangwe paine dambudziko riripo, curve inobuda yemodule haigone kuona nhanho ye curve, asi short-circuit current inofanira kunge iri diki pane yakajairika module, izvo zvinoratidza kuti hot spot phenomenon iripo.
