About solar in Sargodha
Sargodha, Pakistan has a dry climate with long hours of direct sunshine and low humidity. Its annual peak sun hours average 5.15 kWh/m²/day, a excellent solar resource by global standards.
The strongest month in Sargodha is May (spring) at 7.24 kWh/m²/day, and the weakest is December (winter) at 3.06 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.
Sargodha'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 Sargodha?
- Sargodha averages 5.15 peak sun hours per day annually, ranging from 3.06 in December to 7.24 in May.
- How many solar panels do I need in Sargodha?
- Panel count depends on your daily load. At Sargodha's annual average of 5.15 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 Sargodha?
- Sizing against Sargodha's worst month (December, 3.06 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 Sargodha's solar resource compare globally?
- Sargodha sits in solar zone 4 out of 5 (where 5 is strongest) at 5.15 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 often should I clean solar panels in Sargodha?
- Arid climates can drop output 10–20% between cleanings. Quarterly cleaning is typical for Sargodha; monthly during dust-storm seasons. Dew alone isn't enough when rainfall is infrequent.
- Does extreme heat hurt solar output in Sargodha?
- Yes. Panel efficiency drops ~0.4% per °C above 25 °C cell temperature. In Sargodha, midday cell temperatures of 55–70 °C can derate output 12–18% below nameplate.
- Is Sargodha's solar resource as strong as the numbers suggest?
- Sargodha's 5.15 kWh/m²/day is excellent globally. But heat derating and dust accumulation mean real-world yields typically land 10–15% below this headline figure — factor that into sizing.
