Queen’s University in Canada survey into the real cost of implementing solar, reckons the analysts have got it wrong and solar energy is intact already achieving grid parity in some regions.
Cleantechnica.com reports how the study found that analysts were working on costings from 2009, when there’s been a huge drop (as much as 70%) in installation prices.
Also, they’re working on lifetime spans of 20 years for panels when many newer installations are expected to achieve a working life of 30 years.
Previous costings have also factored a 1% drop in solar panel efficiency per year, when the figure for today’s modern units is more like between 0.1% and 0.2% drop in efficiency.
And all this is before you start considering the recent energy price rises.
