摘要: It is possible to give a valuable estimation for an entire solar array IV curve, based only on single working point (current and voltage) measurement, panels of cells, when several their parameters are known environmental also known. The estimations were performed using Matlab/Simulink the simulation 10 parameter cell model. estimated curves slightly deviate from actual measured real panels. average short circuit current error less than 5%, worst case simulated just 33% full lighting included in that average. When open voltage drops error, grows vice verse, so MPP smaller. shown this approach could be used evaluate, line, Maximum Power Point (MPP) panels, while even two or more local maxima exist. relative errors seem 2% with illumination (1 sun), 2.5% 2/3 3% 1/3 illumination. After which not optimal point, has been evaluated, then by new MPP, they can classified re-meandering. Such procedure would require evaluation I/V I/P cell/panels. effectively eliminate problem curve. Once evaluated each panel, it evaluate field after knows, inverter controlled project towards field, thus eliminating need use MPPT module (dc/dc converter).
