  4. Dear sir,
    Please tell me which type of solar cells are more profitable when we consider efficency ,cost and life for 1MW solar power plant.
    Please tell me about most commonly used solar cells for solar power plant.
    Is thin film will give better results than crytline silicon cell?
    Which is better from thin film and crytline silicon?
    And also tell me cost per 1MW of simple crytline silicon and multilayered crytline silicon cell?


  5. In general crystalline Silicon PV Modules have higher efficiency compare to thin film, but in Indian context thin film performs better in hotter states such as Gujarat and Rajasthan, also thin film modules require more space than crystalline

    from a cost perspective chines based crystalline modules are cheaper than US/CAN based thin film modules, So thin-film does not necessarily have competitive price advantage over crystalline

    Thin film is only recommended for commercial applications

    So there is no straight forward answer, it really depends on where your project is located and from where you are sourcing your modules
