Pharmazon Ltd required a detailed assessment of "Feasibility Study and Simulation of the SunBox Concept" in 2025. The work brought together computational fluid dynamics (CFD) and energy and thermal modelling and the project information supplied for this energy application. The central objective was to connect local flow, thermal, transport or process behaviour with system-level performance, risk and design decisions that the client could implement.

This project focused on evaluating the thermodynamic performance of an innovative SunBox solar energy system designed to enhance electricity generation through optimized geometry and operating conditions. Using advanced simulation techniques, a detailed digital model was developed to analyse the thermal and electrical performance of the SunBox under multiple configurations, including south- and east-facing orientations with both fixed and variable tilt angles. Comparative analyses were carried out against a conventional 300 W photovoltaic (PV) panel of equivalent size to quantify the potential gains in power output and efficiency. The study demonstrated the SunBox’s strong potential for performance enhancement in non-optimal orientations, validating it as a proof of concept for next-generation solar technologies. The findings provide valuable insights for design optimisation, energy benchmarking, and the development of high-efficiency building-integrated solar systems.

The methodology centred on a coupled thermodynamic, heat-transfer and electrical-performance model of the SunBox concept. The representation retained the panel geometry, enclosure or optical arrangement, orientation and tilt variables that affect irradiance utilisation, cell temperature and electrical output. Boundary and operating conditions covered south- and east-facing installation, fixed and variable tilt, representative solar and ambient conditions, and comparison with an equivalent conventional 300 W PV panel, with material, fluid and equipment properties assigned from the available design information. Resolution was concentrated in regions where steep velocity, thermal, concentration or phase gradients were expected, while the overall model remained efficient enough to compare several credible configurations. This balance allowed system-level performance to be linked to the local mechanisms responsible for it.

The assessment compared geometry, orientation and operating strategies considered alongside techno-economic performance. Performance was judged using incident and useful energy, cell or system temperature, electrical power and efficiency, orientation sensitivity and potential gain relative to the reference panel. Results were reviewed through quantitative summaries and engineering visualisations, such as contours, vectors, streamlines, sections and time histories, selected to suit the physics. Important assumptions and operating uncertainties were considered so that the recommendations relied on repeatable comparative trends rather than a single nominal case.

For Pharmazon Ltd, the principal value was a quantified proof of concept and a clear basis for design optimisation and building-integrated solar development. The final evidence linked each recommendation to the relevant model or process output, making it suitable for internal design reviews, supplier or contractor discussions and, where applicable, planning, safety or regulatory dialogue. The work also created a reusable baseline that can be updated as geometry, operating data or test results become available, reducing the cost and risk of later design iterations.
