[RE-wrenches] Fire fighters

[Starlight]

To all techies, what if a bleeder resister, similar to what is used on a capacitor, was in parallel with the PV strings or array? That should pull down any high voltage from a low illuminance light source.

Hello the answer is yes.  On a job  several years ago to finish I worked after dark.  It was a full moon, and a street light was nearby I got bit from a 500 Voc module string.  I am sure I did not have 500 V but it only takes 20 ma. To be deadly. I did not get my volt ohm meter out but I should have.

Hi wrenches,

In speaking to local firefighters last year, I had a question that stumped me.  At night, will the light from the flames or the fire fighters' flood lights energize the array to a dangerous potential?

Any light you can shed (pun intended) would be most welcome.

Shine On!
