Under nominal conditions of full irradiance (1000W/sqr-meter) on the panels and a 350V Battery as the load, the power stage of the design achieves a 99% step-down conversion efficiency. This is shown as the steady-state (or final settled) value in the waveform display on the right, which shows the battery input power divided by the output power from the solar panels.</p><p>While the solar panels and the power stage device models represent real components, the battery and control-block/logic functions are generic behavioral elements, intended only to provide a reasonable operating context for the power stage. In particular, this system is set up to assess maximum power point operation under various source and loading conditions.</p><p>The following design can be used to identify the maximum power point load current for just the solar panel, for any user-defined solar irradiance level:</p><p><a href="https://explore.partquest.com/groups/renewable-energy/designs/solar-panel-load-test-maximum-power">https://www.systemvision.com/groups/renewable-energy/designs/solar-panel-load-test-maximum-power</a></p><p>Once that current has been found, it can be used as the target control input (i.e. the panel current command) in this design. Then the efficiency, battery charging current level and other performance metrics can be determined for that operating condition.</p> About text formats Tags Select a tag from the list or create your own.Drag to re-order taxonomy terms.
