CAT 2020 Quant Based LR — Previous Year Question

Rooftop solar power growth has demonstrated an overall positive trend, but this will need to be scaled up massively to achieve the national target.

Assumptions: (I) With ongoing improvements to solar cell efficiency and battery technology, rooftops will only get more attractive in the future. (II) Major solar projects that connect to the grid often face the challenge of land acquisition and transmission connectivity. (III) A survey helps determine usable rooftops, separating them from green spaces, and analyses the quality of the solar resource.
