Can someone explain why the panels are in north/south strips? I would have thought E-W rows pointing south with 39.5 degree incline would be better. Maybe they are actively tilted?

Active tilting and rotating east-west seems to make sense in this configuration.
Edit:
The panels may look like these, the ones installed in P.R. I wonder why they're tilted this way.

Panels can be tilted that way for more even production as the sun moves across the sky. Total production will be lower, but instead of a big peak in production around noon, production is more even over all hours of the day.Active tilting and rotating east-west seems to make sense in this configuration.

An added benefit is that you get better utilization of the solar inverters, as they don't need to handle the peak around noon, but instead handle less power over more time.
So, basically, this way means you have:
- A higher panel cost per kWh
- A lower inverter cost per kWh
- Less efficient land use
- More stable, consistent power production

No non essential spending. Only for increasing capacity or quality. Or just getting metrics for a quarter to understand the roi, or that is what they need for a couple of electric semis?

Any consensus if they need more room to support batteries for 10,000 cars a week? I think this cannsupport model 3 at 10k per week, which is about 30GW annual production. Is new space for more batteries or possibly for semi production?Tesla Gigafactory 1 new aerial pictures tease facility's possible expansion
Tesla paved the new parking lot at the north side
Also a nice image of the new solar installation
The new lot definitely looks big enough to replace all current parking.
Thanks! So it is less efficient, but more useful. The increase in uniformity also reduces storage requirements due to peak spreading.
Crazy to think about the amount of power needed just to give the cells an initial charge...
Does this have to do with PRico being near the equator, i.e. Sun will be more overhead? In Northern Hemisphere in higher latitudes, we are taught that panels need to face south - but is this really true for places nearer to the equator? Just a thought,/curiosity else the above makes sense..
Since Puerto Rico is well south of the Tropic of Cancer, during June and July the noon sun will be high in the northern sky, not the southern. In fact during those months the Sun will be in the northern half of the sky all day.

Good point, Puerto Rico is 18 degrees north latitude. The daily transit is a bigger factor than the inclination.
So true, @Curt Renz , it will get up to 5 degrees the other way.
The butterfly setup makes perfect sense there.
The normal layout would be to point them south with latitude=tilt, so 18 degrees off horizontal. The benefits you get from pointing the panels east/west are basically the same regardless of latitude. I know there are installations here in Norway with the layout. Like: Nå er Norges største solcelle-anlegg blitt nesten tre ganger så stort

How many teeth do you have left? Are you willing to sacrifice for a better good?

Overall sentiment and media coverage is so bearish and negative even "bag holder quotes" is making fun of TSLA longs.
