Panou fotovoltaic policristalin 185 W/24V. NOU, sigiliu fabrica cu factura si garantie. Nu cumpara second hand sau fara acte. Poti lua plasa.

Panourile fotovoltaice sunt dispozitive de inalta tehnologie, care prin natura lor isi pierd in timp caracteristicile de performanta. Dupa 20-25 de ani de exploatare, ele trebuiesc inlocuite datorita randamentului scazut la care ajung dupa acest timp. Este lesne de inteles ca pentru a rezolva corect problema producerii energiei electrice cu ajutorul lor, trebuie sa ne orientam catre produse noi care desi sunt mai scumpe decat cele second-hand, pe termen lung sunt de preferat. Cumparand un produs folosit nu putem sti cat si in ce conditii a fost folosit, deci, nu avem garantia unei utilizari de lunga durata. Este asemenea masinilor: Poti cumpara o masina cu bani putini, dar aceasta te poate "lasa" oricand si vei investi alte sume pentru reparatii. Judecand dupa acest rationament, specialistii in domeniu recomanda instalarea panourilor noi atunci cand se doreste instalarea unei surse de curent fotovoltaic.
