According to a research report from PV Tech, the big-six c-Si module suppliers in the solar PV industry today – Canadian Solar, Hanwha Q CELLS, JA Solar, JinkoSolar, Trina Solar and Yingli Green – are forecast to increase market share again in 2016, taking their collective market share of global module supply to almost 50%.

This inference is based on new research undertaken by the Solar Intelligence research team, that had fully modelled out the expected capacity, production and shipment forecasts for each of the these companies to the end of 2016.

Now, I am not entirely sure if such an oligopoly-like situation is good or bad for the consumers.

Sure, oligopolies, if they want to, can pass on the benefits from economies of scale to the end user, thereby reducing overall panel prices.

Oligopolies, at the same time, can also cartelize themselves and start setting prices.

Thinking a second time, in fact it might be good that it is not exactly an oligopoly (where a few control 80-90% of marketshare), but the rest 50% of the market can possibly ensure that the big boys behave themselves, and possibly pass on the benefits from the economies of scale.
