The simple design methods result in too little flow during months with below-average insolation. A rule-of-thumb chart is presented to predict flow losses for similar installations. To explore possible benefits of tracking strategies, ten different array configurations were simulated: three with fixed orientation, six with single axis tracking, and one with dual axis tracking. Of the three fixed orientation arrays, the configuration to maximize insolation and flow was an equator-pointing array with slope slightly greater than local latitude. The single and dual axis trackers were simulated with seasonal, monthly, and hourly tracking periods, the latter being a good representation of a continuous tracking system. For single axis tracking, a vertical axis array with slope fixed at 30
