Solar Pv Simulation Software
In renewable power generation, solar photovoltaic as clean and green energy technology plays a vital role to fulfill the power shortage of any country. Modeling, simulation and analysis of solar photovoltaic (PV) generator is a vital phase prior to mount PV system at any location, which helps to understand the behavior and characteristics in real climatic conditions of that location. In this context, a single diode equivalent circuit model with the stepwise detailed simulation of a solar PV module under Matlab/Simulink ambience is presented.
I–V and P–V graph of solar PV module provide a broad understanding to researchers, manufacturers and social communities. The simulated result of the PV module is verified by the manufacturer data-sheet of JAP6-72-320/4BB module and maximum relative error percentage is found 1.65% which shows a good agreement between manufacturer values and simulated values.
Moreover, the performance of PV module for real metrological data (irradiance and temperature) shows good results. In addition to this, it is presumed as a sturdy tool to evaluate the performance of any solar PV modules. Previous article in issue. Next article in issue.

Main features and prices included.This independent article has been compiled by Indranil Bhattacharya who has tested each software by running basic simulation exercises. He does not claim to be an expert user or developer of any of these products.
His views are purely subjective and are meant to give the reader a quick insight into these brilliant programs, each of which have unique features to offer and different ways of tackling the same problem.A recent publication by the Ministry of New and Renewable Energy (MNRE) and The Energy and Resources Institute (TERI) listed 7 PV simulation software that are commonly used to design Solar PV systems worldwide. The programs listed are as follows (in alphabetical order):Homer Pro – Homer Energy, USAPV F-Chart – F-Chart software, USApvPlanner – SolarGis, SlovakiaPVsyst – Pvsyst SA, SwitzerlandRETscreen – Natural Resources Canada, CanadaSystem Advisor Model (SAM) - National Renewable Energy Laboratory (NREL), USASolar Pro – Laplace Systems, JapanComparisons of these programs have been made to ascertain how good each are in design and simulation of solar PV power systems. The analysis has been done with focus on SPV power only and hence programs that simulate other sources of renewable energy like wind, biomass, etc. may not necessarily get more preference. Based on the author's individual attempt at using these programs under constant project parameters ratings have been provide at the end of the article.
The following criteria have been considered:. Functions and USP.
User Interface. Historical Weather Data. Module and Inverter Information. PricingHOMER PRODeveloped by NREL (National Renewable Energy Laboratory) USA and later enhanced and distributed by Homer Energy is a micro-grid optimization software.
HOMER stands for Hybrid Optimization Model for Multiple Energy Resources and comes with Simulation, Optimization and Sensitivity Analysis tools.CAPEX and OPEX calculation possible using a project wizard. Simulate multiple energy sources. Add multiple loads. Factors like wind speed, fuel cost and emissions penalties can be included in the calculation.
Location search by name possible. Not specifically designed for Solar PV. Does not generate IV curve data or do shading analysis. Also PV electricity generation report is less comprehensive and detailed due to limited information on weather data and module data. Many loss factors during PV power generation are not added to calculation.Schematic View is useful. Graphical menu system is a plus. Not intuitive and too many parameters to be added manually.Can import TMY2/TMY3 data from NREL website. Also NASA and SolarGIS data can be imported from their websites.
Does not come bundled with free weather data.Can import module data. Only 8 modules (including 1 generic) and 8 (including 1 generic) inverters are included in the program.Cloud licensing available. Fully loaded permanent version available in Commercial USD 4,200/INR 280,000 Educational USD 2,100/INR 140,000 and Student USD 350 annually/ INR 23,407 annuallyScreenshots of Homer version x64 3.6.3. (Fig.1b) Simulation Report PV F-CHARTDeveloped by faculties of University of Wisconsin, PV F-Chart is a PV system analysis design program that uses solar radiation data to calculate PV power generation not taking into account variations caused by PV modules, inverters and other variables. This program is targeted for academic purposes.Simple program that calculates PV energy output based on a generic module and inverter. All data to be added manually and therefore it is difficult to quickly compare generation data by switching module data, site capacity or location. No shading analysis.
Not suitable for calculation of PV power in real world conditions. Simple graph or tabulated data can be generated but cannot be exported.Very basic and handy for calculation when data is entered manually for every parameter. It is a collection of macro enabled spreadsheets. Very limited automation and no wizards available.300 locations are bundled with the software. There is no option to import weather data from common sources like TMY3. Data can only be added manually.No scope for module or inverter data to be added to calculation.Student USD 400/INR 26,750 Academic USD 600/INR 40,000Screenshots of PV F-CHART version 3.55w. (Fig.2b) Monthly Generation, Economic Calculations and Efficiency Report PVPLANNERThis software comes from solar resource database provider SolarGis.
It is a cloud based software that works on the SaaS (software as a service) platform and claims their data is highly accurate and offers a rigorous systematic validation approach increasing data reliability.Accurate satellite data allows user to make estimation of solar radiation and PV power potential of a location and generate report in 14 languages. It automatically calculates terrain shading however there are no options for setting up surrounding structures or do near shading analysis. It is only available as an online version, so an internet connection is mandatory. Allows companies to use their API and access SolarGis through 3rd party apps.Simulation based easy setup in three steps.
Interactive high resolution solar resource maps (iMaps) allow users to accurately pinpoint site location. Interface is neat and intuitive but the performance of the interface could be affected by internet connectivity speeds which is a drawback of online software.Long term annual and monthly average data is included in the basic package. There is no option of importing other data types like NASA, Meteonorm, SAM or user recorded data.Uses generic modules that are based on an average of 18 commonly used modules of various makes and users choose between cSi, CdTe, and CIS modules. Inverter is also a generic one where user can define efficiency.
They claim the variation in most modules is not more than 1.22% which is less than the variation in solar radiation, hence the need to have a module and inverter database does not arise.One location and no map function – USD 560/INR 37,500 PER YEAR.
