What is a photovoltaic (PV) array?
A photovoltaic (PV) array consists of PV panels which can be connected either in series (S-series array) to increase voltage or parallel (P-parallel array) to increase current or both (S-P array) as shown in Fig. 4.2 b.
What is a PV module?
A PV module consists of a number of interconnected solar cells encapsulated into a single, long-lasting, stable unit. The key purpose of encapsulating a set of electrically connected solar cells is to protect them and their interconnecting wires from the typically harsh environment in which they are used.
How many PV panels are connected in series?
Solution: By using Example 4.2, the total voltage of one panel consists of four PV modules connected in series = 18 + 18 + 18 + 18 = 72 V. Now, the total voltage of one array consists of three PV panels connected in series = 72 + 72 + 72 = 216 V.
What is the VOC of a solar PV array?
Suppose a solar PV array contains 20 parallel-connected strings, and each of those strings contains 30 modules connected in series. Each of those modules has a VOC of 28.4 V and ISC of 7.92 A.
