The Problem With Solar Voltaic Cells

I guess it would have been good to find out about the Boron oxide problem before installing 630 GW of solar panels...

But don't forget the immortal words attributed to Winston Churchill. "Perfection is the enemy of progress."

(Yeah, many people earlier expressed this idea using different words. I just like Churchill. )

Yeah but it pales in comparison with the installed capacity vs the actual generation figures...

..."To illustrate how location impacts capacity factor, consider a 10 kW system installed in Phoenix (AZ) vs. Seattle (WA). With a Solar Score of 84, Phoenix has a very high solar energy potential. Using Sunmetrix Discover for Phoenix, we can see that this system would generate about 20,500 kWh of electricity during the year. If it were to run non-stop, 24/7 at peak capacity of 10 kW, it would have generated 24 x 365 x 10 = 87,600 kWh. Dividing 20,500 by 87,600 gives us a capacity factor of about 23%. With a Solar Score of 43, Seattle is an entirely different story. Here, a 10 kW system would generate about 14,000 kWh during the year. Consequently, the capacity factor of the solar energy system here is much lower than that of Phoenix at about 16%."...
