Not exactly, you can't do that kind of calculation. Solar panels work only in full sunlight, and only during the day. When there's cloud coverage, the electricity production goes down drastically. I was giving Topaz solar farm in California as a reference, because it's a solar plant of the same magnitude, in about the same sunlight conditions as India. There's about 3 years of track record for Topaz, and so far its best year (2015), it generated 1.3 TWh/year. We're far from the 5.67 TWh/year that you mention. The best upper limit (theoretical) in a solar farm is about 7 hours of sunlight/day, but that's just the theory. In practice it's always lower.
