At its core, the I-V curve is a graphical representation depicting the relationship between the current (I) and voltage (V) output of a solar cell under varying environmental conditions. It gives a detailed description of its solar energy conversion ability and efficiency. Interconnecting several solar cells in series or in parallel merely to form Solar Panels increases the overall voltage and/or current but does not change the shape of the I-V curve. The system described here (Figure 1) incorporates simple circuitry to step the panel through a variable load in order to “exercise” the panel over a range of current and voltage conditions thereby deter ining the characteristic. . Graphical representation of photo the sun into electrical energy [4, 5, 6, 7, 8]. At present most solar cells. .
