Survey and design a commercial solar and battery system
You are an accredited solar designer and installer in the Solar and Battery team.
What has happened
Kingsley Grammar School wants a 99 kW rooftop photovoltaic system and a 100 kWh battery on its sports centre, job J-26-1171, and needs generation and savings figures for its board meeting on 20 October. The sports centre has a north-facing metal deck roof with a row of skylights, a tree line on the eastern boundary, and a main switchboard rated at 400 A per phase that already supplies the pool plant and the air conditioning. The school has interval metering data for the past year. Network rules limit export for systems of this size and require an export control device. The battery must go in a plant room that also houses the pool chemical dosing equipment.
Deliverables
- Completed job safety analysis for the roof survey
- Site survey record with measurements, shading and switchboard findings
- Preliminary design with array layout, string design, inverter and battery selection and generation estimate
- Draft quotation on the template
- One page board summary

Evidence guide
The survey must be complete enough to design from, with the shading and skylight hazards addressed. The design must respect the switchboard capacity, the network export limits and the battery location rules, and the generation estimate must show its method and assumptions. The quotation should have a clear scope and exclusions and the board summary should be honest about uncertainty.
