Project overview & the research question
What this project asks, why it matters in an arid grid, and how the eight entries build a defensible answer — one current energy system weighed honestly against a future alternative.
The regional energy problem
Bahrain has solved energy access — and now faces energy transition.
The Kingdom delivers electricity to 100% of its population, but almost all of it comes from burning natural gas [1][12]. At the same time the country is unusually sun-rich: global horizontal irradiance is about 2,160 kWh/m² per year, averaging roughly 6 kWh/m² per day [8] Sourced. On paper, that makes solar an obvious move — and Bahrain has committed to it, pledging to lift renewables to 20% of the mix by 2035 and to reach net zero by 2060 [1].
But the same desert sky that delivers the sunlight also delivers the dust. Across the Gulf, airborne dust settles on panels and steadily erodes their output between cleanings — a loss most headline comparisons ignore. That gap between brochure performance and field performance is the problem this project measures and judges.
Most student projects ask "is solar cleaner than gas?" (it is). This one asks the sharper, defensible question an engineer in Bahrain actually faces: how much does dust erode solar's real-world case, and does cleaning close the gap without creating a water problem?
The research question
In an arid grid, does dust soiling erode solar PV's advantage over natural gas enough to change which system better meets the region's energy needs — and can cleaning close the gap without trading an energy problem for a water one?
- Technical — how much output does soiling remove between cleanings, measured on real panels in Bahrain?
- Economic — once cleaning O&M and water are counted, how do gas and solar levelised costs compare under Bahrain's subsidised tariffs?
- Environmental — does solar still win decisively on lifecycle carbon after the soiling and water-for-cleaning penalties?
- Ethical — who bears the water-for-cleaning trade-off in a water-scarce state, and is the transition just?
The two systems, in one view
The assessment is a head-to-head: the incumbent the region runs today versus the alternative it is moving toward.
How the answer is built
Each of the five brief stages has a home in the eight entries, and each leans on evidence rather than assertion.
How to read the evidence
Every number carries a chip so it can be trusted/verified.
Viva readiness
Why frame this as "assess" rather than "describe"?▾
Because the learning outcome (CILO-2) and the A-band rubric reward weighing trade-offs and reaching a justified judgement, not listing facts. The whole site is built to compare two systems on three axes and then commit to a verdict (Entry 6) — with my own data behind it.
Why is soiling the right lens, not just "solar vs gas"?▾
Soiling is the region-specific factor that separates a textbook comparison from a real one. It is measurable cheaply, it shifts the economics (cleaning O&M + water), and it ties straight to SDG 6 and the Gulf's water scarcity — giving the analysis a defensible, original edge.
