About solar in Kom Ombo
Kom Ombo, Egypt has a dry climate with long hours of direct sunshine and low humidity. Its annual peak sun hours average 6.53 kWh/m²/day, a exceptional solar resource by global standards.
The strongest month in Kom Ombo is June (summer) at 8.15 kWh/m²/day, and the weakest is December (winter) at 4.47 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.
Kom Ombo'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 Kom Ombo?
- Kom Ombo averages 6.53 peak sun hours per day annually, ranging from 4.47 in December to 8.15 in June.
- How many solar panels do I need in Kom Ombo?
- Panel count depends on your daily load. At Kom Ombo's annual average of 6.53 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 Kom Ombo?
- Sizing against Kom Ombo's worst month (December, 4.47 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 Kom Ombo's solar resource compare globally?
- Kom Ombo sits in solar zone 5 out of 5 (where 5 is strongest) at 6.53 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 often should I clean solar panels in Kom Ombo?
- Arid climates can drop output 10–20% between cleanings. Quarterly cleaning is typical for Kom Ombo; monthly during dust-storm seasons. Dew alone isn't enough when rainfall is infrequent.
- Does extreme heat hurt solar output in Kom Ombo?
- Yes. Panel efficiency drops ~0.4% per °C above 25 °C cell temperature. In Kom Ombo, midday cell temperatures of 55–70 °C can derate output 12–18% below nameplate.
- Is Kom Ombo's solar resource as strong as the numbers suggest?
- Kom Ombo's 6.53 kWh/m²/day is exceptional globally. But heat derating and dust accumulation mean real-world yields typically land 10–15% below this headline figure — factor that into sizing.
