☀️ Peak sun hours in Bangladesh
Bangladesh gets solid tropical sun — roughly 4.2 to 5 peak sun hours — highest in the dry season and in the west, lower during the monsoon.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| Western Bangladesh (Rajshahi) | ~4.7 – 5.0 |
| Dhaka & central | ~4.4 – 4.8 |
| Chittagong & south-east | ~4.3 – 4.7 |
| Monsoon-season average | ~3.5 – 4.2 |

⚡ Electricity prices in Bangladesh
Grid electricity is billed in rising slabs, relatively affordable at the bottom but climbing for higher use — commonly the equivalent of $0.05–$0.10 per kWh across residential slabs. Higher-consumption homes and businesses gain most from rooftop self-generation.
💸 Incentives & net metering
Bangladesh has a net-metering policy (via SREDA and the distribution utilities) for rooftop systems, allowing export credit, and a globally celebrated solar home system (SHS) programme that electrified millions of off-grid rural households. Confirm current net-metering terms with your utility before sizing an export system.
💰 System cost & payback in Bangladesh
Rough planning guide:
| System size | Approx. cost | Suits |
|---|---|---|
| Solar home system | ~$100 – 600 | Small off-grid rural homes |
| 3 kW rooftop | ~$1,800 – 3,200 | Urban home, net metering |
| 5 kW rooftop | ~$3,000 – 5,200 | Larger home / small business |

💡 Local insight: Bangladesh
Bangladesh is a genuine solar success story: its solar home system programme is one of the largest off-grid electrification efforts ever, reaching millions of rural families with small panel-and-battery kits. In the cities, the story is now shifting to grid-tied rooftops with net metering. Monsoon season noticeably cuts output, so honest production estimates should use dry-season and wet-season figures rather than a single annual average.
