Question

How can we get the required amount of energy by connecting solar panels?

Answer 1

1. Photovoltaic solar cells can be connected in series or parallel to form a solar panel.
2. When solar cells are connected in series, the potential differences (voltages) of the individual cells are added, while the current remains the same as that of a single cell.
3. When solar cells are connected in parallel, the currents of the individual cells are added, while the potential difference (voltage) remains the same as that of a single cell.
4. By using suitable series and parallel combinations, the required voltage and current can be obtained.
5. Several solar panels can also be connected in series and parallel to generate the required amount of electrical energy.
6. A number of solar panels connected in series form a solar string. Several solar strings connected in parallel form a solar array. In this way, the desired voltage, current, and power output can be achieved by appropriately connecting solar panels.
