Diploma in Solar Energy Engineering

Solar engineering rewards people who can move confidently between three languages: astronomy, because the resource is governed by geometry; meteorology, because the atmosphere decides how much of it arrives; and electrical engineering, because a module datasheet is only useful if you can correct it for temperature and irradiance. This diploma teaches all three in the order a designer actually needs them, from the solar constant and the extraterrestrial radiation on a horizontal surface through to string sizing, DC:AC ratio and performance ratio on a commissioned plant.

The programme opens with the routes available for harnessing solar energy — flat-plate and concentrating thermal, photovoltaic, passive and process heat — then works through the nature and attenuation of solar radiation, the full set of geometry angles and their sign conventions, sun-path diagrams and shading analysis, and the instruments and empirical correlations (Ångström–Prescott, diffuse-fraction models) used to estimate monthly average radiation where measured data is thin. Later modules cover collector and thermal-storage performance, semiconductor physics and the one-diode cell model, module manufacturing, mismatch, hot spots, bypass diodes, tracking and MPPT, and close with worked design of stand-alone and grid-connected systems, commissioning tests and loss analysis.

It is written for engineers, technologists, consultants, architects and planners with a working knowledge of physics — light, electricity, basic thermodynamics — who need calculation-level competence rather than a general awareness of renewables. Numerical examples run throughout: incidence angles, day length, tilt factors, battery autonomy, temperature-corrected open-circuit voltage and performance ratio.

Assessment is online: a 30-question final exam with a 70% pass mark, drawn across all eight modules. Successful learners receive a verifiable certificate. Approximately 14 hours of self-paced study.
