Are photovoltaic module prices going down?
The end of photovoltaic module price declines, which became apparent within the last few months, was confirmed by recent investigations. While the average price level was still slightly decreasing at the start of 2013, compared to December 2012, a trend reversal was already visible at the end of January.
Are changes in manufacturing cost & efficiency related to levelized cost of electricity?
This paper attempts to give a comprehensive answer to this question by exploring how changes in manufacturing cost, efficiency, and levelized cost of electricity (LCOE) are related. The basic idea is that paying the cost for an innovation that improves the solar cell efficiency is justified if it results in a reduction in LCOE.
Why are PV module prices rising?
Module prices: New clouds are gathering on the PV horizon as difficult market conditions for modules persist, exacerbated by an unwieldy, if good-intentioned, take-back and recycling scheme. In January, module prices of products from Asia climbed by a few percent age points across the board.
Are solar PV projects economically feasible?
As the solar photovoltaic (PV) matures, the economic feasibility of PV projects is increasingly being evaluated using the levelized cost of electricity (LCOE) generation in order to be compared to other electricity generation technologies.
