ENGN4524 Photovoltaic Technologies (with ENGN6524)

How ENGN4524 is assessed

Both official course pages and the shared 2026 outline publish the same 5/5/30/20/40 weights. ENGN6524 adds research-literature expectations but not a different assessment split.

What ENGN4524 covers

The learning path moves from Solar Resource, Tilt and Tracking, through the problems opened by PV Systems and Performance Metrics, to the synthesis required in Industrial Manufacture and Thin-film Technologies.

It is positioned as a photovoltaic engineering course.

The shared course connects semiconductor loss mechanisms to field systems and lifecycle decisions, with extra research-literature expectations for ENGN6524.

Assessment in ENGN4524 is distributed as follows: 5% online quizzes, 5% tutorials, 30% individual exercises, a 20% group project and a 40% final examination

The operational assessment conditions matter here.

The final is a three-hour centrally invigilated open-book examination with calculators allowed and a supplied formula sheet.

What makes ENGN4524 demanding is concrete: keeping solar geometry, device physics, circuit behaviour, field performance and economics unit-consistent across one design argument

Treat the ENGN4524 hurdle status as unconfirmed.

Check the current official course outline for any component-level pass rule before relying on the overall mark.

For enrolment planning, Basic circuit analysis, physics and computing are assumed; semiconductor knowledge is helpful but not essential.

The learning path moves from Solar Resource, Tilt and Tracking, through the problems opened by PV Systems and Performance Metrics, to the synthesis required in Industrial Manufacture and Thin-film Technologies.

Diagnose a shaded PV string

Key terms

Irradiance

Instantaneous solar power incident per unit area. This chapter uses the concept when students convert horizontal resource into a defensible plane-of-array estimate.

Irradiation

Solar energy received per unit area over a stated interval. It helps explain the reasoning required to convert horizontal resource into a defensible plane-of-array estimate.

Plane-of-array resource

Direct, diffuse and reflected solar energy incident on a tilted receiver. Its limit matters because weather, horizon and model choice limit geometry-only estimates.

Band gap

Energy separation controlling which photons can generate mobile charge carriers. This chapter uses the concept when students trace photon absorption through carrier generation, separation and collection.

Electron–hole pair

Mobile negative and positive carrier pair created by sufficient excitation. It helps explain the reasoning required to trace photon absorption through carrier generation, separation and collection.

P–n junction

Junction whose internal field separates photogenerated carriers. Its limit matters because a band diagram is a model and recombination can prevent collection.

Open-circuit voltage

Cell voltage when terminal current is zero. This chapter uses the concept when students read I–V and P–V curves and diagnose the loss controlling maximum power.

Fill factor

Ratio of maximum electrical power to the rectangle formed by open-circuit voltage and short-circuit current. It helps explain the reasoning required to read I–V and P–V curves and diagnose the loss controlling maximum power.

Parasitic resistance

Series or shunt resistance that distorts the cell curve and reduces power. Its limit matters because temperature, irradiance and measurement conditions must remain attached to the curve.

Series string

Cells or modules connected so their voltages add while the same current flows. This chapter uses the concept when students predict array I–V behaviour under interconnection, shading and mismatch.

Mismatch loss

Power loss caused when interconnected devices have unequal electrical characteristics. It helps explain the reasoning required to predict array I–V behaviour under interconnection, shading and mismatch.

Bypass diode

Protection path allowing string current around a reverse-biased cell group. Its limit matters because ideal scaling fails when current limits, reverse bias and diode states differ.

Encapsulation stack

Layered module structure protecting cells while transmitting light and carrying load. This chapter uses the concept when students translate specifications and stress mechanisms into a reliability judgement.

Standard test conditions

Reference irradiance, spectrum and cell temperature used for module ratings. It helps explain the reasoning required to translate specifications and stress mechanisms into a reliability judgement.
