Career mode. Run Bahrain's solar plants against the desert — dust eats your output at the project's real measured −0.79%/day, storms dump it in bulk, dew cements it on, and every wash costs precious desalinated water. Read the forecast. Time your washes. Earn the stars.
Every number is the project's evidence: −0.79%/day measured on paired panels in Bahrain (Entry 5) · 24,000 L per MW-wash [11] · Doha 12–24%/month losses [5] · dew cementation [4] · gas-vs-solar carbon gap [3] · 6 peak-sun-hours [8] — all in the references.
Retention decays −0.79%/day (my measured rate). Keep it above 95% and never meet a shamal with an empty tank.
Your plant earns energy every daylight hour — but the desert dusts your panels at −0.79% output per day (the rate this project measured on real panels in Bahrain). Your one job: decide when to wash.
Each wash restores 100% but drains desalinated water from a finite tank. Waste it early and you'll watch a shamal storm bury your panels with nothing left to fight back.
The 5-day forecast under the scene shows what's coming: 🌪 storms spike dust instantly, 💧 dew cements it (faster decay until washed), 🌬 wind cleans a little free. Keep retention ≥95% to build a 🔥 score streak. Good luck.
