Re: Important Q for electrical engineers: Covering solar panels for Panama Canal transit - possible damage?

Hi Scott, open circuiting the panels, as you said, means no current and no hotspots/damage. just wanted to clarify, the switches are between the panels and charge controllers, NOT between the controllers and the battery? (If the latter, you should make sure you shade the panels first before you open the switch. depending on topology, some charge controllers do not like getting their output open circuited under load.) Seems like the former so you're OK. now the bypass diode issue is different, in partial shading, bypass diodes should *bypass* shaded modules and reduce panel hotspots. the diodes should be sized to carry a lot of current & not get damaged. another issue for another time. happy crossing kelly + ryan SM233 Iteration Boston
