"Should I wait for dry season?" Many people in Port Harcourt, Warri and Yenagoa ask this. Here is the honest answer.

Dry season

About November to February.

  • Roofs are dry. Work is easier.
  • Panels produce well (with some harmattan haze).
  • Busy season for installers, so book early.

Rainy season

About March or April to October.

  • Work happens in dry windows between showers.
  • Everything is sealed against rain.
  • You start saving fuel right away.

What matters more than the month

Prices follow exchange rates and supply more than seasons. Waiting for a lower price often costs more in fuel than you save.

Should I size my system for dry season?
