Solar Eclipse Power

Description Did you know? During the recent solar Eclipse PV panel voltages only dropped by 15%  Dragons Breath measured the iridescence during the recent solar eclipse and found that that heat was the only thing to drop dramatically. This goes to show you that the Voltages in solar panels are still very high during Sun set times.  Always measure voltages and current before disconnecting any supply during daylight.  Temperatures dipped down to 5 degrees while the sun’s rays were obscured, Theses reductions happened for approximately 20 minutes until the moon had traveled across the Suns surface.  Electrical readings when using a 75w solar panel showed that the system voltage was 19.5v just before the totality, during this event the readings dropped to 16.5v. This provided valuable information into diagnostics and understanding cloud or partial daylight with module power generation.
