The post discusses advancements in satellite technology used to estimate global solar energy potential, highlighting improvements in calculating roof pitch and optimizing energy capture. However, users express skepticism about the relevance of individual rooftop installations due to logistical issues and emphasize that large-scale solar deployments may be more efficient. The conversation also brings attention to discrepancies in solar energy projections and suggests the potential for significantly higher photovoltaic (PV) adoption than current estimates. Overall, while the technology is promising, its practical application and integration into existing infrastructure raises important questions.
