Plot Solar & Orientation Analyzer
Exact sun geometry for your Faisal Hills plot — how the sun crosses it through the year, the best solar-panel angle, the coolest room layout, and how to catch the natural breeze. Pick your plot’s road-facing direction to get tailored, accurate guidance.
Location: Faisal Hills (33.73°N). Sun geometry is computed exactly for this latitude.
Sun path across the year
| Season | Noon sun height | Daylight | Sunrise / sunset bearing |
|---|---|---|---|
| Summer (Jun) | 80° | 14.2 h | 61° / 299° |
| Equinox (Mar/Sep) | 56° | 12.0 h | 90° / 270° |
| Winter (Dec) | 33° | 9.8 h | 119° / 241° |
In summer the sun is nearly overhead at noon and rises in the NE / sets in the NW; in winter it stays low in the south and rises ESE / sets WSW. This is what drives heat and shading on each wall.
Solar panels
Best fixed tilt: 30° facing due south (seasonal: ~17° summer, ~49° winter). A 5 kW system here generates roughly 25.0 kWh/day (~750 kWh/month) at ~5 peak-sun-hours. Mount on the roof or the south side; keep the south roof clear of water tanks/parapet shadow.
Orientation & room layout — East-facing plot
Place bedrooms on the EAST or NORTH (gentle morning light, cool afternoons). Keep the main lounge/drawing room on the SOUTH for warm winter sun that is easy to shade in summer. Put service spaces (kitchen, stairs, baths, store, car porch) on the WEST as a heat-buffer against the harsh afternoon sun.
West and south-west walls take the most heat (afternoon sun + summer 'Loo'). Use deep overhangs/chajjas (≈0.5-0.6m) over south windows, minimise west-facing glazing, and consider a double wall or vertical shading on the west. A light-coloured roof + insulation cuts peak summer load sharply.
Islamabad's prevailing breeze is from the NORTH-WEST. Place primary openings on the NW and an outlet on the SE for cross-ventilation; stack/roof vents help exhaust hot air. Avoid sealing the NW face.
