About solar in Suez
Suez, Egypt has a temperate climate with meaningful seasonal variation in solar resource. Its annual peak sun hours average 6.13 kWh/m²/day, a exceptional solar resource by global standards.
The strongest month in Suez is June (summer) at 8.34 kWh/m²/day, and the weakest is December (winter) at 3.6 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.
Suez's exceptional solar resource means panels can be sized close to demand rather than heavily oversized, which keeps installation costs down.
FAQ
- What are the peak sun hours in Suez?
- Suez averages 6.13 peak sun hours per day annually, ranging from 3.6 in December to 8.34 in June.
- How many solar panels do I need in Suez?
- Panel count depends on your daily load. At Suez's annual average of 6.13 kWh/m²/day, a 5 kWh/day load needs roughly 3 × 400 W panels. Use the calculator above for your actual load.
- What size battery do I need in Suez?
- Sizing against Suez's worst month (December, 3.6 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 Suez's solar resource compare globally?
- Suez sits in solar zone 5 out of 5 (where 5 is strongest) at 6.13 kWh/m²/day — exceptional 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 Suez?
- Suez's worst month (December) delivers 3.6 kWh/m²/day — about 43% of the summer peak of 8.34. Off-grid systems here typically oversize 1.5–2× or pair with a backup source.
- Do cloudy days significantly affect Suez's solar?
- Partly. Diffuse light still produces 10–25% of clear-sky output. Suez's 6.13 kWh/m²/day already reflects average cloudiness, so no further derating is needed for sizing.
- What panel tilt works best in Suez?
- At Suez's latitude (30°), a fixed tilt near 30° balances year-round yield. Winter-heavy loads favor latitude + 15°; summer-heavy, latitude − 15°.
