Ha lefats'e le ntse le tsoela pele ho batla matla a tsitsitseng le a nchafatsoang, matla a letsatsi e se e le tlholisano e kholo peisong ea ho fokotsa mesi e ntšang khabone le ho loantša phetoho ea maemo a leholimo. Bohareng ba sistimi ea letsatsi ho na le filimi ea ethylene vinyl acetate (EVA), e bapalang karolo ea bohlokoa ho sebetseng hantle le ho tšoarelleng ha liphanele tsa letsatsi.
Filimi ea Eva ke copolymer e bonaletsang ea thermoplastic e sebelisoang haholo ho paketeng ea li-module tsa photovoltaic. Mosebetsi oa eona o ka sehloohong ke ho sireletsa lisele tse fokolang tsa letsatsi linthong tse kang mongobo, lerōle le khatello ea mechine, ha ka nako e ts'oanang ho netefatsa hore khanya ea letsatsi e fetisetsoa liseleng tsa letsatsi ka katleho. Karolo ena e habeli e etsa hore lifilimi tsa EVA e be karolo ea bohlokoa tlhahisong ea liphanele tsa letsatsi tsa boleng bo holimo.
E 'ngoe ea melemo e meholo ea lifilimi tsa EVA ke bokhoni ba tsona ba ho eketsa ts'ebetso le bolelele ba liphanele tsa letsatsi. Ka ho koahela lisele tsa letsatsi ka katleho, lifilimi tsa EVA li sebetsa e le tšitiso ho kenelleng ha mongobo, li thibela ho bola le ho hloleha ha motlakase ho ka fokotsang katleho ea liphanele. Ho phaella moo, phetiso e phahameng ea khanya ea lifilimi tsa EVA e lumella ho kenella ha khanya ea letsatsi ka ho fetisisa, ka hona ho ntlafatsa ts'ebetso ea phetoho ea matla ka har'a sele ea letsatsi.
Holim'a moo,Lifilimi tsa Evae bapala karolo ea bohlokoa botsitsong ba mechini ba liphanele tsa letsatsi. Litšobotsi tsa eona tse matla tsa sekhomaretsi li netefatsa hore lisele tsa letsatsi li hokahane ka thata le liphanele esita le tlas'a maemo a thata a tikoloho joalo ka mocheso o feteletseng le moroalo oa moea.

Ntle le mesebetsi ea eona ea tšireletso le ea sebopeho, lifilimi tsa EVA li thusa ho ntlafatsa katleho ea litsamaiso tsa letsatsi ka kakaretso. Ho lumellana ha eona le mefuta e fapaneng ea mahlale a lisele tsa letsatsi le lits'ebetso tsa tlhahiso ho e etsa khetho e feto-fetohang le e theko e tlase bakeng sa ho kenngoa ha liphanele tsa letsatsi. Ho feta moo, tšebeliso ea lifilimi tsa EVA e lumella tlhahiso ea liphanele tsa letsatsi tse bobebe le tse tenyetsehang, e fanang ka menyetla ea ho kenya liphanele tsa letsatsi tse ncha le tse bolokang sebaka.
Tšusumetso ea tikoloho ea lifilimi tsa EVA litsamaisong tsa letsatsi le eona ea bohlokoa ho eloa hloko. Ka ho sireletsa lisele tsa letsatsi le ho atolosa bophelo ba liphanele tsa letsatsi, filimi ea EVA e thusa ho eketsa tlhahiso ea matla ka nako e telele, e fokotsa tlhoko ea ho nkeloa sebaka khafetsa le ho fokotsa litšila. Sena se lumellana le lipheo tsa botsitso tsa Renewable Energy Initiative 'me se totobatsa bohlokoa ba lifilimi tsa EVA ho khanneng phetoho ea matla a hloekileng.
Ho ea pele, lipatlisiso le nts'etsopele e tsoelang pele lefapheng la lifilimi tsa EVA tsa letsatsi li shebane le ho ntlafatsa litšobotsi tsa tsona tsa ts'ebetso, joalo ka ho hanyetsa UV, botsitso ba mocheso le ho sebelisoa hape.
