About solar in Ankara
Ankara, Turkey has a temperate climate with meaningful seasonal variation in solar resource. Its annual peak sun hours average 4.68 kWh/m²/day, a good solar resource by global standards.
The strongest month in Ankara is July (summer) at 7.66 kWh/m²/day, and the weakest is December (winter) at 1.73 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.
Ankara'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 Ankara?
- Ankara averages 4.68 peak sun hours per day annually, ranging from 1.73 in December to 7.66 in July.
- How many solar panels do I need in Ankara?
- Panel count depends on your daily load. At Ankara's annual average of 4.68 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 Ankara?
- Sizing against Ankara's worst month (December, 1.73 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 Ankara's solar resource compare globally?
- Ankara sits in solar zone 3 out of 5 (where 5 is strongest) at 4.68 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.
- How much does winter reduce solar output in Ankara?
- Ankara's worst month (December) delivers 1.73 kWh/m²/day — about 23% of the summer peak of 7.66. Off-grid systems here typically oversize 1.5–2× or pair with a backup source.
- Do cloudy days significantly affect Ankara's solar?
- Partly. Diffuse light still produces 10–25% of clear-sky output. Ankara's 4.68 kWh/m²/day already reflects average cloudiness, so no further derating is needed for sizing.
- What panel tilt works best in Ankara?
- At Ankara's latitude (40°), a fixed tilt near 40° balances year-round yield. Winter-heavy loads favor latitude + 15°; summer-heavy, latitude − 15°.
