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

Solution
- Photovoltaic solar cells can be connected in series or parallel to form a solar panel.
- 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.
- 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.
- By using suitable series and parallel combinations, the required voltage and current can be obtained.
- Several solar panels can also be connected in series and parallel to generate the required amount of electrical energy.
- 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.
