Solar PV power is the only source of green energy

Solar pv power is the only source of green energy and to remain till the day of judgment or till the end of the WORLD as all segments of religious way of life!
why India so slow with all tropical climate conditions more suitable for solar than any other countries but even coldest country like Switzerland /other countries hurrying in switching over solar an ultimate energy source !
India estimates 1,00,000 MW by 2020 and 2030 2 lakhs MW with a duration of 6 and 16 years respectively. one side domestic content in enjoying additional advantages from GOVT and other installations.

Considering solar pv production line in India (may consider max 500 MW per annum),in 16 years available panels in India based on 500 mw per annum = 8,000MW only.

Let us assume that in 16 years another 1000mw solar pv production line is added it is another 16,000 MW only total 16,000+ 8.000= 24,000 MW only, rest of panels from out source 3,00,000 mw minus 24,000 = 2,76,000 MW is to be imported and this 2,76,000MW should be available within 2030 with all requisite efficiency to meet the generation assured is another problem? besides implementation of 3,00,000 mw within 2030 with all modality of bidding process which is very cumbersome and no transparency as the conditions imposed by bidding authorities leads an opportunity only to either grown MNC's or bureaucracy even 10,000 mw per annum ,will take another 30 years? how come within 16 years 3,00,000 mw of solar pv power plants completion is possible is another?
A forecast on energy generation by Hydro, Thermal, Wind and nuclear may become obsolete over a period purely on environmental and other aspects by then if you are not ready with an assured alternate source of solar based energy.
