How to evaluate V-I characteristic and PV characteristic of solar cell?

V-I characteristic and PV characteristic of solar cell at nominal temperature and irradiance are evaluated by using simulink model shown in fig 2. Varying resistive load is connected at the output and output power is depends on the parameter value of load.

How to configure a PV array?

Configuration of PV arrays depends on required rated voltage and current of a power plant. If Ns cells are connected in series and Np cells are connected in parallel then equation of Ipv can be expressed as:

How many cells are connected in a solar array?

Hence there are 72 cells in series and two strings of 72 cells are connected in parallel (Ns=72 and Np = 2). Solar array model is shown in figure 3 and specifications of one module and complete array are mentioned in the table 2 and table 3. Figure 3: PV array model. Table2: Electrical Specification of test module.

What is the power output of a photovoltaic solar cell?

You have learnt previously that the power output of a photovoltaic solar cell is given in watts and is equal to the product of voltage times the current (V x I). The optimum operating voltage of a PV cell under load is about 0.46 volts at the normal operating temperatures, generating a current in full sunlight of about 3 amperes.

What are the Design & sizing principles of solar PV system?

DESIGN & SIZING PRINCIPLES Appropriate system design and component sizing is fundamental requirement for reliable operation, better performance, safety and longevity of solar PV system. The sizing principles for grid connected and stand-alone PV systems are based on different design and functional requirements.

How to setup a solar array in a power plant?

This configuration can be setup by connecting PV module in series and parallel connections and this group of several PV modules assembled in a PV tray is called as Solar array. Configuration of PV arrays depends on required rated voltage and current of a power plant.
