The software is not specific to each power source. You must specify one power source that you will use.

If for solar energy, the best are PVsyst and PVsol.

Homer optimization

Homer can be used for hybrid power system

Regarding Wind Energy, I would recommend OpenWind for flat terrain conditions. On complex terrain conditions it is advisable to run a more sophisticated CFD tool - such as WindSim, Meteodyn or some OpenSource implementation.

For performance predication and design analysis of HAWT & VAWT, I prefer freely available QBlade (http://www.q-blade.org)

Dear Haseeb Shah ,

HOMER is the world-class and best tool for techno-economic software.

You can simulate with the world standard components and thousands of simulations within a few minutes.

HOMER Pro is the very powerful tool for the techno-economic feasibility analysis of off-grid Microgrids/Minigrids.

In our country, most of the Minigrid project developers, the professionals, and the researchers are using HOMER Pro.

HOMER Grid the very useful for Grid-connected systems.

Very sincerely

Dear Haseeb Shah ,

I shared my articles in RG that simulated by HOMER Pro and HOMER.

You can see how valuable of HOMER.

Is there any open-source alternative to Homer Pro?

i would recommend PVsyst since it is user friendly and easy to use,however you can also try hommer as others have suggested

Greenius Simulation software for the technical and economical calculations as they are needed for planning and installation of renewable power projects such as:

Solar thermal parabolic trough power plants, Photovoltaic systems, Wind parks and Dish/Stirling systems.

The below mentioned review cites several references on mathematical modelling of biomass pyrolysis , which produce biofuels; a type of renewable energy. Happy new year.

RETScreen and this month they are offering 1 year free for education institution

RETScreen software is a useful tool for the feasibility study of the techno-economic analysis of all renewable technologies.

TSOL software is a good software for SWH and Polysun is a good software for PVT or GSHP systems

do your simulations with MATLAB. A software usually does not consider some aspects and linearizes many formulas. So use your own code and write a fitness function code in MATLAB M-file and finally enjoy a wide range of optimization algorithms.
