About solar in Mardan
Mardan, Pakistan has a warm, tropical climate with a distinct wet and dry season. Its annual peak sun hours average 5.14 kWh/m²/day, a excellent solar resource by global standards.
The strongest month in Mardan is June (summer) at 7.55 kWh/m²/day, and the weakest is December (winter) at 2.83 kWh/m²/day. When sizing a year-round off-grid system, it's standard practice to design against the December value rather than the annual average — otherwise the battery bank runs low during the darkest weeks.
Mardan's solar conditions are well within the range where off-grid PV is a straightforward engineering exercise with standard-sized arrays and lithium batteries.
FAQ
- What are the peak sun hours in Mardan?
- Mardan averages 5.14 peak sun hours per day annually, ranging from 2.83 in December to 7.55 in June.
- How many solar panels do I need in Mardan?
- Panel count depends on your daily load. At Mardan's annual average of 5.14 kWh/m²/day, a 5 kWh/day load needs roughly 4 × 400 W panels. Use the calculator above for your actual load.
- What size battery do I need in Mardan?
- Sizing against Mardan's worst month (December, 2.83 kWh/m²/day) with 2 days of autonomy at 80% depth of discharge, a 5 kWh/day load needs about a 12.5 kWh battery bank.
- How does Mardan's solar resource compare globally?
- Mardan sits in solar zone 4 out of 5 (where 5 is strongest) at 5.14 kWh/m²/day — excellent by global standards. For reference, top-tier desert sites average ~6.5 and high-latitude cities around 2.5 kWh/m²/day.
- How does the wet season affect solar generation in Mardan?
- Mardan's dry-season output peaks at 7.55 kWh/m²/day in June; the wet season drops it to 2.83 in December. That ~92% swing is a key sizing consideration.
- Can solar panels survive tropical storms in Mardan?
- Most tier-1 PV panels are rated for 140+ mph wind loads; mounting hardware usually fails first. In cyclone-prone regions like Pakistan, specify IEC 61215-certified panels and anchor-bolt mounts rather than ballasted.
- What's the dry-to-wet output gap in Mardan?
- Mardan swings from 7.55 kWh/m²/day in June (dry) to 2.83 in December (wet) — roughly 92%. Year-round off-grid systems must size against the wet-season minimum.
