To increase the current of solar panels, there are several strategies, including: 1. Using Higher Quality Materials, 4. Incorporating Sun Tracking Systems. Among these, enhancing efficiency is a critical aspect which involves upgrading the solar. . The behavior of an illuminated solar cell can be characterized by an I-V curve. 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. PV panels can be connected in groups to form a PV array.
