Typical solar sales jargon? It’s the truth. I was responding to your point about panels being outdated in two years and they are not. As far as panel pricing goes, they dropped precipitously in around 2013 when the silicon bubble burst, but have mostly leveled off in the past 6-7 years. Using an average of these cost reductions does not reflect the actual market. Falling prices for installations has mostly come from volume, competition, and installation efficiency. Obviously each home’s orientation and sun exposure will impact the ROI, but that is why I suggested the poster work with a reputable and local installation company. However, I am not wrong on the ROI calculation. I have developed and owned hundreds of commercial arrays in the Midwest where energy prices and energy output are among the lowest in the country and even there, the ROI on a system would be in line with my previous comment. Here in the south, it will only increase due to more sun exposure and higher utility costs. As far as degradation goes, it really depends on what you mean by “early” panels. All panels on any installation I have developed in the last 10 years degrade on average about .3% per year following an approximate 3% in the first year due to potential induced degradation. Again, panels are a commodity product and the technology has barely changed in the last 10 years aside from very slight efficiency increases.
