Design, Operate, and Analyze Solar Arrays with ETAP

Photovoltaic (PV) array (groups of Solar Panels) is a growing power source globally. It is commonly used in micro grid, renewable energy, and smart grid projects. Solar radiation is used to create DC current, and then converted to AC current through inverters. ETAP PV Array models panels connected in series and/or parallel combinatio
Voltage (P-V) curves and Current-Voltage (I-V) curves are defined in ETAP using the Library or manually by specifying parameters including:ns with an inverter to simulate and analyze arrays.

The PV array element is part of the ETAP Renewable Energy system module and is fully integrated with all ETAP calculation modules such as Load Flow, Short circuit, Harmonics, Coordination, Transient Stability, and ETAP Real-Time.

(Vmp-p) – Maximum Peak Power Voltage

(Imp-p) – Maximum Peak Power Current

(Voc) – Open Circuit Voltage

(Isc) – Short Circuit current


Irradiance and cell temperature are used as performance coefficients to automatically recalculate the power output from the Photovoltaic array. It also includes an irradiance calculator than can calculate the solar irradiance for any geographic location. The irradiance calculator is especially useful when estimating or pre-designing a new system.


Key Features
