SISIFO is an online, free-software, simulator of PV systems developed by the IES-UPM.
SISIFO is an online, free-software, simulator of PV systems developed by the IES-UPM in the frame of the European projects PVCROPS and MASLOWATEN. The current version of SISIFO allows the simulation of different types of grid-connected PV systems (such as large grid-connected plants and building-integrated installations) and of PV irrigation system (direct pumping or into a water pool).
To use SISIFO, you must provide information about the location of system, the solar resource data and the technical characteristic of the system. Using this information SISIFO predicts the performance of the PV system and can generate a simulation report in pdf.
For a detailed description of SISIFO, see the Technical reference manual , or get an overview.
