The program's capstone: a new community solar + storage design assignment, a drawing-interpretation exercise across all 6 real projects, a field troubleshooting exercise, a grading rubric, and your certificate of completion.
This closing module is not a new topic — it is where everything from Modules 1 through 20 gets applied to one more design problem this program has not already solved for you: a 3.0 MW-DC ground-mount community solar project paired with a 1.5 MW / 3.0 MWh battery energy storage system, sized against a real utility firm-export cap and a 350-subscriber bill-credit structure. A worked PV string sizing calculation with cold- and hot-temperature checks, a PV+BESS export-coordination narrative, an interconnection and code-compliance narrative, and a financial analysis anchor the assignment in the same shown-work discipline this program has used throughout.
Completing this module's quiz below marks the whole program complete and unlocks your certificate of completion from the program hub — a self-issued personal completion record and portfolio artifact, not a licensing credential or NABCEP certification.
