Simple and Accurate I-V Measuring Circuit for Photovoltaic
The present paper presents an implement of a simple and accurate current – voltage measuring circuit for various types of photovoltaic modules based on an electronic load. The
The following figure shows PV panels connected in series configuration. With this series connection, not only the voltage but also the power generated by the module also increases. To achieve this the negative terminal of one module is connected to the positive terminal of the other module.
A Solar Photovoltaic Module is available in a range of 3 WP to 300 WP. But many times, we need power in a range from kW to MW. To achieve such a large power, we need to connect N-number of modules in series and parallel. A String of PV Modules When N-number of PV modules are connected in series.
Step 1: Note the current, voltage, and power requirement of the PV array Step 2: Note the PV module parameters Voltage at maximum power point of module VM = 70 V Current at maximum power point of module IM = 17 A Maximum power PM: PM = VM x IM PM = 70V x 17A PM = 1190 W Step 3: Calculate the number of modules to be connected in series and parallel
The entire string of series-connected modules is known as the PV module string. The modules are connected in series to increase the voltage in the system. The following figure shows a schematic of series, parallel and series parallel connected PV modules. PV Module Array To increase the current N-number of PV modules are connected in parallel.
