About solar in Erzurum
Erzurum, Turkey has a continental climate with cold winters and warmer summers. Its annual peak sun hours average 4.87 kWh/m²/day, a good solar resource by global standards.
The strongest month in Erzurum is July (summer) at 7.61 kWh/m²/day, and the weakest is December (winter) at 2.09 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.
Erzurum'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 Erzurum?
- Erzurum averages 4.87 peak sun hours per day annually, ranging from 2.09 in December to 7.61 in July.
- How many solar panels do I need in Erzurum?
- Panel count depends on your daily load. At Erzurum's annual average of 4.87 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 Erzurum?
- Sizing against Erzurum's worst month (December, 2.09 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 Erzurum's solar resource compare globally?
- Erzurum sits in solar zone 3 out of 5 (where 5 is strongest) at 4.87 kWh/m²/day — good by global standards. For reference, top-tier desert sites average ~6.5 and high-latitude cities around 2.5 kWh/m²/day.
- Does snow block solar panels in Erzurum?
- Yes — snow cover can drop output to near zero. In Erzurum's winter months (around December), brush panels after significant snowfall or design with steep tilt (45°+) so snow slides off naturally.
- How much does winter hurt solar output in Erzurum?
- Erzurum's worst month is December at 2.09 kWh/m²/day versus 7.61 in July — a 113% seasonal swing. Off-grid continental systems usually combine oversized arrays with wood-stove or generator backup.
- Is solar worth it in a continental climate like Erzurum's?
- Yes, but the seasonal ratio matters. Erzurum's annual 4.87 kWh/m²/day is solid; grid-tied net metering works well (summer credits offset winter draw). Full off-grid needs generator or hydro backup.
