I-ZRPT i-flat single axis inkqubo yokulandelela i-solar enemodyuli ethambekileyo yindibaniselwano ye-flat single axis inkqubo yokulandela umkhondo welanga kunye nenkqubo yokulandelela i-axis enye. Ine-axis enye ethe tyaba yokulandelela ilanga ukusuka empuma ukuya entshonalanga, kunye neemodyuli zelanga ezifakwe kwi-5 - 10 degrees tilted angle. Ilungele ubukhulu becala imimandla yobubanzi obuphakathi nophezulu, khuthaza ukuveliswa kwamandla akho malunga nama-20%.
