🧭 “It’s not just about facing the sun — it’s about chasing it smartly.”
🌍 Why Tilt Angle Matters
Solar panels work best when they are perpendicular to the sun’s rays.
Since the sun’s position changes throughout the year, the best angle for your panels also changes.
Getting this right can boost your solar output by 10–20%, especially in Nigeria’s tropical zones where we have both rainy and dry seasons.
☀️ Nigeria’s Solar Climate
- Nigeria lies roughly between latitudes 4°N and 14°N
- That gives us strong solar radiation year-round, but the sun is higher in the sky during some months
🌞 Dry Season (Nov–March):
The sun is almost directly overhead → Panels should be flatter (lower tilt)
🌧️ Rainy Season (April–Oct):
The sun sits lower in the sky (towards the south) → Panels should be tilted more steeply
📐 Recommended Tilt Angles (Fixed Systems)
| City/Region | Recommended Tilt (Fixed) |
|---|---|
| Lagos | 10° – 12° |
| Abuja | 11° – 15° |
| Kano | 14° – 18° |
| Port Harcourt | 10° – 13° |
| Jos | 13° – 17° |
If you can only pick one angle:
➡️ Use your latitude as the base (e.g., Lagos ≈ 6° + add 5–10° for better rainy season capture)
🧠 Pro Tip: Seasonal Adjustment (If You Want to Get Fancy)
If you have a manual adjustable frame, you can do:
- Dry season tilt: Latitude – 10°
- Rainy season tilt: Latitude + 10°
This can increase annual energy yield by 5–8%, but it’s only worth it for high-efficiency commercial or off-grid systems.
🏗️ How Jeho Ashar Optimizes Tilt
- We assess your roof pitch and direction (azimuth)
- Use angled aluminum structures if your roof is flat
- Factor in seasonal shadows (trees, water tanks, neighboring buildings)
- Offer seasonal adjustment options for larger systems
💬 What If My Roof Can’t Be Tilted?
No worries. Even flat-roof installations still work well — we just:
- Use tilting brackets or custom frames
- Optimize placement using software tools like PV*Sol or Helioscope
- Prioritize energy use matching (more panels = longer harvest window)
🧮 Real-World Example: Jeho Ashar Client in Jos
System size: 4kW
Roof angle: Flat
Used a 15° tilt frame facing due south
Got +18% more energy during rainy season vs. neighbor’s flat install!
🔚 Final Word
Tilt matters more than you think.
It’s not about looking good—it’s about catching the most sun when it counts.
At Jeho Ashar Energy, we don’t just install panels — we design high-performance systems tailored to your roof, region, and real-world needs
