Mumakore achangopfuura, matunhu ekumaodzanyemba kwakadziva kumabvazuva kweChina akasangana nekukanganiswa nemadutu, nemamiriro ekunze akaipisisa zvichikonzera kurasikirwa kukuru kwehupfumi kuzvigadzirwa zvemuno nehupenyu hwezuva nezuva. Kuchinja kwemamiriro ekunze kwakakonzera kuwedzera kwezviitiko zvemadutu ane simba guru uye zviitiko zvemamiriro ekunze akasimba, zvichikonzera zviitiko zvakawanda zvekukundikana kwechimiro chemagetsi ezuva (PV), kupidigurwa kwemamodule, uye kuora kwezvikamu nekuda kwe "kutsemuka kwakavanzika." Zvichiwedzerwa nemafambiro akadai sekuwedzera kwehukuru hwemamodule uye kumanikidzwa kwekugadzirisa mitengo, kuramba kwemutoro wemakanika uye kuvimbika kwenguva refu kwemamodule ePV kuri kusangana nematambudziko ari kukura. Nekuda kweizvozvo, kutevedzera mitemo yemutoro unoshanduka kwave kwakakosha pakuona kuchengetedzeka kwenguva refu uye mashandiro ekuisa solar.
Parizvino, nzvimbo dzekushanda kwezviteshi zvemagetsi zvePV munzvimbo dzine mhepo ine simba dziri kuramba dzichiwedzera kusiyana-siyana uye dzakaoma, kubva kunzvimbo dzinoitika madutu egungwa kusvika kunzvimbo dzemhepo dziri mukati menyika, imwe neimwe ichiratidza mamiriro ekunze akasiyana. Pasi pemutemo weIEC 61215 uripo—uchitsanangura mamiriro ekuyedza e±1000 Pa kwema cycles chiuru—kukwanisa kwePV modules kudzivirira mhepo kunoenderana nekumhanya kwemhepo kwe130 km/h (36.1 m/s), kwakaenzana neDutu reChikamu 12 pachikero cheSaffir-Simpson. Zvisinei, muzviitiko zvedutu remhepo chaiyo, mhepo dzakasimba kwazvo dziri pedyo nenzvimbo ine dutu dzinogona kusvika kuCategories 14–15. Nekuda kweizvozvo, maitiro ekuyedza aripo anokundikana mukudzokorora kuneta kwemhepo inochinja-chinja uye mhedzisiro yekubatana kwemhepo nemhepo. Kunyangwe mamodules anopfuura chitupa cheIEC anogona kuramba achikuvara mumamiriro ekunze akaipisisa.
Uyezve, bvunzo dzinoshanda nguva dzose uye dzemazuva ano dzinotsanangurwa muIEC standards dzinoshanda senzira yekutanga yekuongorora uye hadzitevedzere zvakakwana mhedzisiro yekuneta inokonzerwa nekusangana nemhepo ine simba kwenguva refu muhupenyu hwese hwemodule. Miedzo iyi inosanganisira mazinga ekushushikana akaderera uye kuverengerwa kwema cycles mashoma, zvichitadza kufunga nezvemhepo yakawandisa uye zvinodiwa zvekugara kwenguva refu mukati memakore makumi maviri nemashanu kana kupfuura ekushanda. Musiyano uyu unounza njodzi dzinogona kuitika dzemhando yepamusoro dzingakanganisa mashandiro akachengeteka uye akavimbika ema PV systems muhupenyu hwavo hwese, zvichizopedzisira zvakanganisa kukosha kwemushandisi wekupedzisira uye kudzoka kwemari yaanoisa.
Zvichienderana nekusiyana kwemamiriro emhepo munzvimbo dzakasiyana-siyana, pane chikonzero chekukurumidzira chekuwedzera kugona kwePV modules kutakura mutoro. Pfungwa yechinyakare ye "mhepo inodzivisa mwero" imwe chete haichakwani kuve nechokwadi chekuti kuiswa kwakachengeteka munzvimbo dzakasiyana siyana dzekushandisa. Pane kudaro, ma module load ratings anofanirwa kupatsanurwa zvakanyanya zvichienderana nemamiriro chaiwo ezvakatipoteredza uye ma profiles enjodzi dzenharaunda.
Pasi rose, nyika dzinosanganisira United States, nyika dzeEurope, neJapan dzakaisa zvinodiwa zvakanyanya zve dynamic load munzvimbo dzine mhepo ine simba. Semuenzaniso, sisitimu yeUL certification muUS inokurudzira mamwe ma parameter ekuyedza e ±1500 Pa yema cycles 10,000 munzvimbo dzakadai seFlorida neGulf Coast, uko mhepo dzemadutu dzinowanzoitika. Saizvozvowo, chirongwa cheTÜV Rheinland cheExtended Reliability Testing (ERT) chinosanganisira bvunzo dze dynamic load dzakavandudzwa—dzakadai se ±1600 Pa yema cycles 12,000—dzakagadzirirwa kushandiswa munzvimbo dzine mhepo ine simba ine simba seNorth Sea neBaltic Sea muEurope. Humbowo hwechokwadi hunoratidza kuti kushandisa mwero we dynamic load wakakwira—kazhinji ±1500 Pa yema cycles 10,000—munzvimbo idzi kwakaderedza zvakanyanya kutadza kushanda zvakanaka uye kukuvara, nokudaro zvichivandudza kuchengetedzeka kwekushanda uye hupenyu hwema PV installations.
Mumamiriro ekunze epasi rose anochinja-chinja, kusimba kwesimba rePV modules hakusisiri chinhu chehunyanzvi chinosarudzwa asi chinhu chikuru chinoratidza kuchengetedzeka kwemiti uye mashandiro emari muhupenyu hwese. Kuti zvizadzise zvinodiwa neindasitiri, kuvandudzwa kwetekinoroji kunoramba kuripo uye kuvandudzwa kwemitemo yepasi rose kwakakosha. Kuburikidza nekuvandudzwa kwakakwana kwemhando yechigadzirwa uye kuoma kwekuyedza chete, zviteshi zvemagetsi zvePV zvinogona kuchengetedza kusimba kwechimiro uye kuvimbika kwekushanda munzvimbo dzisingatarisirwi, nokudaro zvichipa kukosha kwakasimba uye kwenguva refu kune vatengi vekupedzisira.
