In looking at some of these smaller installations I also notice that the panel angles are sometimes closer to horizontal than I would have suspected. On further research I understand that the power density per acre can be increased by using these lower angles and thereby reducing the spacing between arrays. This appears to result in a configuration that produces more AC power per acre. I would guess that these systems run higher AC to DC ratios.to optimize system performance. . I can understand that if someone looked only at the array configuration it could be argued that they are suboptimal. However from a system standpoint (array, inverter and land), they may be optimizing the ROI.
