Looking into the growing usage of renewable energy, it’s a good grab for those inclined toward the solar energy and have an understanding of the calculations associated with PV cells. Globally a formula E = A x r x H x PR is followed to estimate the electricity generated in output of a photovoltaic system.
The principle of solar photovoltaic is to convert solar energy of light (photons) into electricity. When photons heat special materials they create a displacement of electrons that generate a continuous current. Solar cells are connected in series to form photovoltaic panels that are connected together to crate a PV generator.
A photovoltaic system is designed to supply usable solar power by means of photovoltaics. It entails arrangement of several components including solar panels which absorb and convert sunlight into electricity, a solar inverter which changes the electric current from DC to AC and other electric accessories like cable to set up a working system.
Be aware that this nominal ratio is given for standard test conditions (STC) : radiation=1000 W/m2, cell temperature=25 celcius degree, Wind speed=1 m/s, AM=1.5. The unit of the nominal power of the photovoltaic panel in these conditions is called "Watt-peak" (Wp or kWp=1000 Wp or MWp=1000000 Wp).
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.
