PV Array & Solar Panel

Photovoltaic Array Analysis Software

Design, Analyze & Operate Solar Farms with ETAP
Photovoltaic (PV) array is one of the important elements of renewable energy, microgrid, smart grid, etc. It converts solar radiation energy into direct current using semiconductors and then to alternating current electric power through inverters.

ETAP Photovoltaic Array is used to represent individual panels connected in series and parallel combinations with a grid tied inverter in order to simulate and analyze grid connected solar farms.


Key Features

  • Model unlimited solar panels individually or in groups
  • Series and/or parallel connection combinations to form a solar array
  • User-defined solar panel library with P-V and I-V characteristics
  • Solar irradiance calculator
  • Determine irradiance in watts per square meter based on specified date, time and location
  • Simulate solar irradiance changes and its effect on the solar farm output
  • Create multiple solar irradiance categories for predictive “what if” studies & scenarios
  • Built-in inverter model eliminates the need for unnecessary node connections
  • Model behavior of Maximum Peak Power Tracking (MPPT) Controller for Inverters

Photovoltaic array element is part of the ETAP Renewable Energy system and is fully integrated with all ETAP calculation modules such as Load Flow, Short circuit, Transient Stability, Harmonic Analysis, Protective Device Coordination, and ETAP Real-Time solutions.

The characteristics of the photovoltaic such as the Power-Voltage (P-V) curve and the Current-Voltage (I-V) curve can be defined in ETAP using the Photovoltaic Library or manually specifying the Maximum Peak Power Voltage (Vmp-p), Maximum Peak Power Current Imp-p, Open Circuit Voltage (Voc) and Short Circuit current (Isc).

ETAP considers the effect of performance coefficients such as changes in irradiance and cell temperature and can automatically recalculate the power output from the Photovoltaic array.

The Photovoltaic array elements also includes an irradiance calculator than can calculate the solar irradiance incident upon a location. Solar Irradiance is the power per unit area available at a location due to solar radiation.

The solar irradiance calculator is especially useful when designing or estimating electrical power output from the panels without knowledge of the entire network.

Methods for Evaluating DC Arc Incident Energy in PV Systems

Renewable energy systems continue to be one of the fastest growing segments of the energy industry. This presentation focuses on the understanding of how photovoltaic (PV) technology behaves under dc arc conditions. A comparative analysis of the arc flash incident energy calculation method developed in collaboration between National Renewable Energy Laboratory (NREL) and ETAP details the effect of PV module I-V and P-V curves under arcing conditions. Examples of the application of the proposed calculation method to the test measurements are included.
