Ha ho batloa litharollo tsa matla a tsitsitseng, matla a letsatsi a hlahile e le mokhoa o mong o tšepisang ho feta mafura a setso a mesaletsa ea lintho tsa khale. E 'ngoe ea likarolo tsa bohlokoa tlhahisong ea liphanele tsa letsatsi ke tšebeliso ea filimi ea ethylene vinyl acetate (EVA). Thepa ena e ncha e bapala karolo ea bohlokoa ho eketseng bokhoni le ho tšoarella ha liphanele tsa letsatsi, e leng se etsang hore e be karolo ea bohlokoa ho sebeliseng matla a letsatsi.
Filimi ea letsatsi ea EVA ke thepa ea thermoplastic e sebelisetsoang ho koahela lisele tsa letsatsi ka har'a li-module tsa photovoltaic. Mosebetsi oa eona o ka sehloohong ke ho sireletsa lisele tsa letsatsi linthong tse kang mongobo, lerōle le mahlaseli a UV, ha ka nako e ts'oanang e fana ka ho thibela motlakase le ho ntlafatsa phetiso ea leseli ea module. Sena se eketsa tlhahiso ea matla le ho lelefatsa bophelo ba liphanele tsa hau tsa letsatsi.
E 'ngoe ea melemo e meholo ea ho sebelisa filimi ea letsatsi ea EVA ke bokhoni ba eona ba ho ntlafatsa ts'ebetso eohle ea phanele ea letsatsi. Ka ho koahela lisele tsa letsatsi ka katleho, filimi e thusa ho boloka botšepehi ba module, e netefatsa hore e ka mamella maemo a leholimo a thata le ho pepesehela khanya ea letsatsi nako e telele. Sena se lumella liphanele tsa letsatsi ho hlahisa tlhahiso ea matla e tšepahalang le e sebetsang haholoanyane, e leng se etsang hore e be tharollo ea matla e sebetsang le e tšoarellang.
Ntle le thepa ea eona ea tšireletso,lifilimi tsa letsatsi tsa EVAho kenya letsoho ho tšoarelleng ha tlhahiso ea matla a letsatsi. Ho sebelisa thepa ena tlhahisong ea liphanele tsa letsatsi ho thusa ho fokotsa tšusumetso ea tikoloho ea tlhahiso ea matla ka ho sebelisa mehloli ea matla a nchafatsoang le a hloekileng. Sena se tsamaisana le boiteko ba lefats'e ba ho fokotsa phetoho ea tlelaemete le ho fokotsa mesi e ntšang khabone, e leng se etsang hore lifilimi tsa letsatsi tsa EVA e be karolo ea bohlokoa ea phetoho ho ea bokamosong ba matla a tsitsitseng haholoanyane.
Ho phaella moo, ho tšoarella le ho phela nako e telele ha lifilimi tsa EVA tsa letsatsi ho kenya letsoho ho etseng hore litsamaiso tsa letsatsi li sebetse hantle ka kakaretso. Ho sebelisa filimi ea EVA ho thusa ho eketsa phaello ea matsete a merero ea letsatsi ka ho netefatsa botšepehi ba nako e telele le ts'ebetso ea liphanele tsa letsatsi. Sena se etsa hore letsatsi e be khetho e sebetsang moruong bakeng sa lits'ebetso tsa bolulo le tsa khoebo, e leng se etsang hore ho amoheloe litharollo tsa matla a nchafatsoang.
Ha tlhoko ea matla a hloekileng le a nchafatsoang e ntse e tsoela pele ho hola, karolo ea lifilimi tsa EVA tsa letsatsi tlhahisong ea liphanele tsa letsatsi e ntse e e-ba ea bohlokoa haholo. E eketsa bokhoni, ho tšoarella le botsitso ba litsamaiso tsa letsatsi, e leng se etsang hore e be karolo ea bohlokoa phetohong ea ho ea sebakeng sa matla se tsitsitseng le se mosa tikolohong.
Ka kakaretso,lifilimi tsa letsatsi tsa EVAli bapala karolo ea bohlokoa tšebelisong ea matla a letsatsi 'me li thusa ho ntlafatsa bokhoni, ho tšoarella le botsitso ba liphanele tsa letsatsi. Ha lefats'e le ntse le batla ho fokotsa ho itšetleha ha lona ka mafura a mesaletsa ea lintho tsa khale le ho fetohela mehloling e hloekileng ea matla, tšebeliso ea lifilimi tsa EVA tlhahisong ea liphanele tsa letsatsi e tla tsoela pele ho ba matla a susumetsang nts'etsopele ea litharollo tsa matla a tsitsitseng. Ka ho sebelisa matla a lifilimi tsa EVA tsa letsatsi, re ka bula tsela bakeng sa bokamoso bo khanyang le bo tsitsitseng bo tsamaisoang ke matla a letsatsi.
