The reduction in the soft costs has also been primarily driven by hardware improvements: more practical system designs might speed up installation, reducing labour or permit costs.
Do hardware and non-hardware features reduce the cost of solar photovoltaics?
The cost of solar photovoltaics has declined over the past two decades, but the driving mechanisms are not fully understood. Now, researchers examine the role of hardware and non-hardware features in cost reduction of photovoltaics and develop a model that could be used to understand cost reductions for other energy technologies.
Why is solar photovoltaic technology so expensive?
Since the early 2000s, the total cost of solar photovoltaic (PV) technology has consistently sunk below expert expectations, mostly due to hardware improvements.
