When our clients have a low pitch to the roof, we can use ballasted, non-penetrating basket-style racks, such as the Ecofoot 2+ shown here. On a low pitched roof is we need to add roof anchors on the low side to keep the solar system from moving down hill. In the case of this solar array, we needed only four anchors with sealed roof boots, to satisfy the code regarding snow and wind conditions.
A few well-placed roof anchors prevent the solar array from moving down the roof, while the pavers on the PVC baskets prevent uplift.
