Solar Design for 2 story Residence and ADU in Tustin CA
S3DA Design provided solar engineering design services for a two-story residence and accessory dwelling unit in Tustin, CA. The project focused on developing a clear, permit-oriented photovoltaic system design tailored to the energy needs of both structures while supporting code-compliant residential performance.
S3DA’s Scope
- PV solar system calculations and performance assessment
- Low-voltage cable calculations
- General single-line diagram
- Technical specifications for the inverter
- Technical specifications for the PV modules
Key Challenges & Solutions
Residential solar design requires careful coordination between system performance, equipment selection, and electrical documentation. S3DA approached the project with a streamlined engineering process, preparing the core calculations and technical documentation needed to support a well-coordinated solar installation. This reflects S3DA’s broader design philosophy of delivering practical, efficient, and integrated engineering solutions with a single-source approach.
The Result
The result is a focused solar design package that supports project clarity, system efficiency, and smoother permitting for a residential property with an ADU in Southern California.
