| Ceiling fans | 3 | 2.5 kWh |
| LED lighting | 6 | 0.4 kWh |
| Washing machine | 1 | 0.5 kWh |

Recommended System Size for 5 Marla House
| Monthly Bill | System Size | System Cost | Expected Saving |
|---|---|---|---|
| Rs 5,000–8,000/month | 3 kW on-grid | Rs 230,000–280,000 | Rs 5,000–8,000/month |
| Rs 8,000–15,000/month | 4–5 kW on-grid | Rs 310,000–400,000 | Rs 8,000–15,000/month |
| Rs 15,000–25,000/month | 5–6 kW on-grid | Rs 380,000–470,000 | Rs 12,000–20,000/month |
For most 5 marla homes in Pakistan, a 3–5 kW on-grid system is the sweet spot. The 3 kW system covers basic loads; the 5 kW system covers a 1-ton AC plus all household loads, with net metering surplus for evening credit.
5 Marla House: How Many Solar Panels?
| System Size | 600W TOPCon Panels | Roof Area Required | Cost |
|---|---|---|---|
| 3 kW | 5 panels | ~140 sq ft | Rs 230,000–280,000 |
| 4 kW | 7 panels | ~195 sq ft | Rs 310,000–360,000 |
| 5 kW | 8–9 panels | ~250 sq ft | Rs 380,000–440,000 |
A 5 marla house typically has 800–1,000 sq ft of total roof area but only 400–600 sq ft is usable (excluding water tanks, staircase head, shading from adjacent buildings). A 5 kW system needing ~250 sq ft fits comfortably on most 5 marla rooftops.
With or Without Battery for a 5 Marla House?
| Situation | Recommendation | Extra Cost |
|---|---|---|
| Load shedding 6–10 hrs/day | 3–5 kW hybrid + 7 kWh battery | Rs 300,000–350,000 extra |
| Load shedding 2–4 hrs/day | 5 kW on-grid — net metering sufficient | No battery needed |
| No load shedding | 5 kW on-grid only | — |
| Off-grid (no grid connection) | 5 kW + 10–14 kWh battery bank | Rs 450,000–600,000 extra |
For 5 marla homes in areas with 6+ hours of load shedding, a 5kW hybrid system with 2× Pylontech US3000C batteries (7 kWh) is the most popular configuration in 2026. Total cost: Rs 680,000–800,000. Payback: 20–28 months. The battery covers evening loads while solar covers daytime.
