A cautious approach to PV technology change

While First Solar and SunPower have set out ambitious roadmaps, capex from Asian-based suppliers is still being kept to minimal levels, explains Finlay Colville, vice president of NPD Solarbuzz.
The rationale for technology roadmaps and buy-cycles is easy to accept. Overcapacity cycles are typically followed by capex downturns, which are in turn followed by a shift to advanced technologies and the introduction of new processes.Looking at the photovoltaics industry, it is clear that the first part of this equation occurred during 2011 – 2013, …
