How Solar Cells Work

The solar panels that you see on power stations and satellites are also called photovoltaic (PV) panels, or photovoltaic cells, which as the name implies (photo meaning "light" and voltaic meaning "electricity"), convert sunlight directly into electricity. A module is a group of panels connected electrically and packaged into a frame (more commonly known as a solar

Calculation & Design of Solar Photovoltaic Modules & Array

When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
