I'm a solar engineer dedicated to the design of Grid Interactive Systems at a medium to residential scale (using PVSyst only residential):
1. Site assessment: Minimum space required, solar data
2. Module selection: Datasheet comparisson and selection between most of the brands (e.g. Jinko, Longi, Seraphim, Trina etc.) and assesment on new technologies: Bifacial, half-cut and PERC
3. Array sizing: Max. Voc and Max Isc (series parallel connection)
4. Support structure sizing: Type and list of materials
5. Wiring sizing: Minimum conductor sizing, type of cable needed, installation accessories
6. Disconnect and overcurrent protections sizing
7. Inverter sizing: Datasheet comparisson and selection between most of the brands (e.g. Sungrow, Huawei, Kstar, Fronius, Outback etc.)
And the sizing of MV power r using ETAP.
Furthermore, I translate C1-Level English, B2-Level German and B2-Level French content (may be in the field of engineering) into Spanish(native language).
