From about December to February, harmattan haze can reach Port Harcourt, Warri, Asaba and Yenagoa. It is milder than in Kano or Abuja, but you will notice it on your solar output.
What changes
| Effect | Why |
|---|---|
| Hazy skies | Dust in the air blocks some sunlight |
| Dusty panels | No rain to wash them |
| Cooler mornings | Panels actually work a bit better when cool |
What to do
- Rinse panels every 2 to 4 weeks. See how to clean panels safely.
- Watch your inverter's daily solar total. If it drops, clean.
- Use the grid or generator top-up on very hazy days if you have a hybrid inverter.
Harmattan + soot
In Port Harcourt, dust mixes with soot. That makes a sticky film. Read soot and solar panels.
Good news
Dry season also means dry roofs. It is a great time to install. Read best time to install solar.
