I didn't realize that there would be more penetrations with more rows. I'd prefer to minimize penetrations to minimize the chance of a roof leak. Let's stick with your original design; I'll circumnavigate around the panels when climbing onto the roof. Regarding the batteries, inverters, and other equipment: that sounds fine. Let's move ahead with the project. Please tell me what I need to do next.
