A few days ago I did solar production calculations for a location in south florida around 27 lattitude. There is concern about wind from hurricanes so it was suggested that the panels could just be flat on the ground. And sure enough it works!! there are 4 months in winter that the production drops by 20% but the rest of the year production is 100-105%. When we were on vacation in St Croix a few years ago I had seen an array flat on the ground in front of a business but that was below the tropic of cancer meaning the sun is a little north of them in the summer... but hey, looks like southern Florida is close enough. Conventional wisdom says set your panel tilt at your latitude.... and if I did that at this location in south Florida, the seasonal production variability is +/-9% So flat may be worth it especially when they don't use heat in the winter and flat mitigates the risk of wind damage.
