While he is biased against solar, many of the points he makes are valid. Solar PV has grown so fast that lifetime and recycling problems are only starting to get serious attention. Many panels have short lives due to quality issues brought on by the extreme pressure to reduce costs. The backing material in many panels has been reduced to inadequate protection levels and many junction boxes are defective. Glass based panels are difficult and expensive to recycle and are mostly dumped in landfills where they leach heavy metals. Solar financials are based on 30 year panel lifetimes which are not likely to be achieved.
Stratosolar uses lightweight panels and are not exposed to water based corrosion. They produce three or more times as much energy per panel.
