Software for electrical / solar photovoltaic systems design

[Miguel Esteban-Perez]

Good Afternoon
Does anyone know an UK / Brit Software for electrical / solar photovoltaic systems design?
French software is starting to get small for the KWpeak that I´m designing and maybe we could have an UK alternative.
If not, does anyone know an EEUU electrical design software?
Regards
