Mu myaka ya vuba aha, uturere two mu majyepfo y'uburasirazuba bw'Ubushinwa tw’inkengero z'uburasirazuba twahuye n'ingaruka z'inkubi z'umuyaga, aho ikirere cyagize ingaruka zikomeye ku bukungu bw'umusaruro wo mu gace ndetse n'ubuzima bwa buri munsi. Ihindagurika ry'ikirere ryatumye inkubi z'umuyaga ziyongera cyane ndetse n'ibihe bikomeye by'ikirere, bigatuma habaho ibibazo byinshi byo kwangirika kw'inyubako z'amashanyarazi ya photovoltaic (PV), guhindagura module, no kwangirika kw'ibice bitewe n'"imivuniko yihishe." Bitewe n'impinduka nko kwiyongera kw'ingano ya module n'umuvuduko wo gukoresha neza ibiciro, kudakomera k'umuvuduko w'amashanyarazi no kwizera igihe kirekire kwa module za PV biri guhura n'imbogamizi ziyongera. Kubera iyo mpamvu, kubahiriza amahame agenga umuvuduko w'amashanyarazi byabaye ingenzi mu kwemeza umutekano w'igihe kirekire n'imikorere y'ingufu zikomoka ku mirasire y'izuba.
Muri iki gihe, imiterere y’imikorere ya sitasiyo z’amashanyarazi za PV mu turere duhura n’umuyaga mwinshi irimo kugenda irushaho kuba itandukanye kandi igoranye, kuva mu turere twibasirwa n’inkubi z’umuyaga ku nkombe kugeza ku nzira z’umuyaga wo mu gihugu, buri imwe igaragaza imiterere y’ikirere itandukanye. Dukurikije ibipimo bya IEC 61215 bihari—bigaragaza imiterere y’igerageza rya ± 1000 Pa ku ngendo 1.000—ubushobozi bwo kurwanya umuyaga bwa module za PV bungana hafi n’umuvuduko w’umuyaga wa kilometero 130 ku isaha (36.1 m/s), bingana n’inkubi y’umuyaga yo mu cyiciro cya 12 ku gipimo cya Saffir-Simpson. Ariko, mu bihe by’inkubi z’umuyaga, umuyaga mwinshi uhoraho hafi y’aho inkubi y’umuyaga iherereye ushobora kugera ku byiciro 14-15. Kubera iyo mpamvu, amabwiriza y’igerageza ariho ubu ntakora neza mu kwigana umunaniro w’umuyaga uhoraho mu isi nyayo no guhuza ingaruka z’umuyaga n’imitingito. Ndetse na module zatsinze icyemezo cya IEC zishobora kwangirika mu bihe by’umuyaga ukabije.
Byongeye kandi, ibizamini bihoraho n'ibisanzwe bikoreshwa mu bipimo ngenderwaho bya IEC bikora nk'uburyo bw'ibanze bwo gusuzuma kandi ntibigaragaza neza ingaruka z'umunaniro uterwa no guhura n'umuyaga mwinshi igihe kirekire mu gihe cyose cy'akazi ka module. Ibi bizamini birimo urwego ruto rw'imihangayiko n'umubare muto w'ingendo, ntibibarwe ku mubare w'umuyaga ukabije n'ibisabwa mu gihe kirekire mu gihe cy'imyaka 25 cyangwa irenga yo gukora. Iki cyuho gishyira ingaruka zishobora guterwa n'ubwiza zishobora kwangiza imikorere myiza kandi yizewe ya sisitemu za PV mu gihe cyose cy'ubuzima bwazo, amaherezo bigira ingaruka ku gaciro k'umukoresha n'inyungu ku ishoramari.
Bitewe n’ihindagurika ry’imiterere y’umuyaga mu turere dutandukanye tw’isi, hari hakenewe byihutirwa kongera ubushobozi bwo gutwara imizigo bwa module za PV. Igitekerezo gakondo cy’"igipimo kimwe cyo kwirinda umuyaga" ntikigihagije kugira ngo gikoreshwe mu buryo butekanye mu bihe bitandukanye byo gukoreshwa. Ahubwo, amanota y’imizigo ya module agomba gutandukana cyane hashingiwe ku miterere yihariye y’ibidukikije n’imiterere y’ibyago byo mu karere.
Mu rwego mpuzamahanga, ibihugu birimo Leta Zunze Ubumwe za Amerika, ibihugu by'i Burayi, n'Ubuyapani byashyize mu bikorwa ibisabwa bikomeye byo gutwara amashanyarazi mu turere duhura n'umuyaga mwinshi. Urugero, sisitemu yo gutanga icyemezo cya UL muri Amerika isaba ko hakorwa ibizamini by'inyongera bya ± 1500 Pa ku nshuro 10.000 ku turere nka Florida na Gulf Coast, aho umuyaga ukunze kugaragara mu nkubi y'umuyaga. Mu buryo nk'ubwo, gahunda ya TÜV Rheinland yo Gupima Ubuziranenge (ERT) ikubiyemo ibizamini byo kongera imbaraga mu gutwara amashanyarazi—nk'aho ± 1600 Pa ku nshuro 12.000—byagenewe gukoreshwa mu turere twibasirwa n'inkubi y'umuyaga mwinshi nko ku nkombe z'inyanja ya Ruguru n'inyanja ya Baltique mu Burayi. Ibimenyetso bigaragaza ko gushyiraho amahame yo hejuru y'imbaraga mu gutwara amashanyarazi—ubusanzwe ± 1500 Pa ku nshuro 10.000—muri utu turere byagabanyije cyane igipimo cyo kwangirika no kwangirika kw'ubutaka, bityo bikongera umutekano muri rusange mu mikorere no kuramba kw'ibikoresho bya PV.
Muri iki gihe, imihindagurikire y’ikirere ku isi ikomeje kwiyongera, ubushobozi bwo kwihanganira imitwaro ya PV ntabwo bukiri ikintu cy’ingenzi mu bya tekiniki ahubwo ni ikintu cy’ingenzi kigena umutekano w’inganda n’imikorere yazo mu gihe cyose. Kugira ngo ibyo inganda zisaba bihuze n’iterambere, guhanga udushya mu ikoranabuhanga no kunoza amahame mpuzamahanga ni ngombwa. Ni mu kunoza ubwiza bw’ibicuruzwa no gupima neza, aho ingufu za PV zishobora kugumana ubuziranenge bw’imiterere n’ubwizigirwa mu mikorere ahantu hadateganyijwe, bityo bigatanga agaciro gahoraho kandi k’igihe kirekire ku bakiriya bazo.
