Solar PV has great future potential. Perhaps by 2030, solar PV will rule. But 2030 is a far distance away. Until then, how can the world overcome the key bottlenecks presented by solar PV based power generation?
Here is a post from EAI that discusses this, especially in the context of India.
In a way, as the blog post also discusses, it is always a chicken-egg story; if solar PV is used on massive scales, costs will come down significantly and for solar PV to be used on large scales, it needs lower costs. Rather than trying to figuring out which comes first, I think we should probably start doing both - through a mix of government incentives and private initiatives.
What do you think?
