Tech­nol­ogy: Thin film and crys­talline

Power Watch India - - COVER STORY -

By steadily build­ing some of the coun­try’s largest so­lar ca­pac­i­ties, we are try­ing to prove that green energy is doable and can be made af­ford­able through rapid ex­pan­sion. To achieve this goal we have been part­ner­ing with Tier 1 tech­nol­ogy part­ners. This en­sures that we achieve high level qual­ity bench­marks at our pro­ject sites and touch op­ti­mal plant per­for­mance stan­dards. We have been us­ing both thin film and crys­talline tech­nolo­gies at our pro­ject sites, as both are con­ducive for In­dian cli­matic con­di­tions. Both vari­a­tions of pho­to­voltaic tech­nolo­gies have their own unique ad­van­tages and are cho­sen on the ba­sis of dif­fer­ing fac­tors.

Crys­talline tech­nol­ogy for ex­am­ple, is avail­able with higher DC plate rat­ing there­fore, the num­ber of crys­talline mod­ules used are less. How­ever, thin film of­fers lesser tem­per­a­ture co­ef­fi­cient as com­pared to crys­talline PV mod­ules while the BOS cost per MW in crys­talline tech­nol­ogy is lesser than thin film due to a dif­fer­ence in ef­fi­ciency. A ma­jor im­pact would be on the mount­ing struc­ture cost and it can be ap­prox­i­mately 1.6 times in the case of high ef­fi­ciency thin film PV mod­ule. Thin film of­fers a unique light soak­ing ef­fect and lower tem­per­a­ture co­ef­fi­cient; there­fore higher energy out­put can be ex­pected from mod­ules. - Vi­neet Mit­tal, Vice Chair­man, Wel­spun Re­new­ables
