Pros and cons of software used for sizing process of RES-based plants.

	Pros	Cons
Homer Pro	- Straightforward to use; - Sizing optimization tool.	- Solutions are based on first degree linear equations; - Limited libraries for models of energy conversion systems.
TRNSYS	- Dynamically simulation of any energy conversion system for electric and thermal energy production with high resolution; - Modelling of both buildings and plants.	- Time consuming; - Technical expertise.
HOGA	- Multi objective optimization; - Simulation with high time resolution	- Lack of sensitivity and risk analysis; - Maximum limits on daily electric loads.
Hybrid2	- Availability of several electric load options; - Comprehensive dispatching alternatives.	- Absence of models from own library; - Ignore the dynamic behaviour of the thermal and electric energy systems.
RETscreen	- Large weather database; - Excel based tool.	- Ignore the dynamic behaviour of the thermal and electric energy systems. - Disregard the dynamic performance of thermal and electric energy systems
