Project overview
This project looks at a day school where lighting, the computer lab, the staff room and the office all operate during the school day. That pattern lines up closely with solar generation, making most of the output directly usable.
The challenge
A fictional scenario
In this fictional scenario, outages interrupt computer lessons and office work, and the school's electricity budget is under pressure. Usage drops sharply in the evenings, at weekends and during holidays, so the design needs to avoid paying for capacity that would sit idle.
Proposed system configuration
Rooftop arrays across two classroom blocks feed a hybrid inverter. A modest battery supports the computer lab, office and security lighting during outages, while the rest of the school runs on solar and grid power. The system is set not to export to the grid.
Installation considerations
- Roof survey of both classroom blocks, including the condition of older iron-sheet roofing.
- Installation scheduled during the school holidays to avoid disrupting lessons.
- Cable routes and equipment kept out of reach of pupils, with lockable enclosures.
- Holiday settings agreed so the battery stays healthy when the school is closed.
Illustrative outcome
What the design aims to achieve
- 01
Most daytime school loads are designed to run on solar when sunlight is available.
- 02
The computer lab and office are intended to stay available during typical outages.
- 03
The bursar can track generation against the school's electricity bills.
Outcomes describe design intent for a fictional scenario. They are not measured results or a guarantee of performance. Real-world results depend on actual consumption, weather, equipment and site conditions.
