When light goes, many homes in Port Harcourt reach for rechargeable fans and lamps. They help. But are they cheaper than solar in the long run?

What rechargeables do well

  • They are cheap to buy.
  • No installer needed.
  • Good for a few hours.

Where they fall short

  1. They need light to charge. If NEPA does not bring light, they stay empty.
  2. Batteries wear out. Most die in 1 to 2 years.
  3. They are small. One fan, one room.
  4. No fridge, no TV.

A family example

A family buys 3 rechargeable fans and 4 lamps. They replace them often. They still run a generator for the TV and fridge. Over a few years, that adds up to a lot.

A 3kVA system runs all of it from the sun. No fuel. No buying fans again.

A good middle step

If budget is tight now, start with a small system and grow it later. Read start small and expand your solar and solar for fans and lights only.

Frequently asked questions

How long does a rechargeable fan last at night?

Usually a few hours on high speed and longer on low. When the battery ages, it gets shorter.

Can a rechargeable fan charge from solar?

Some come with a small solar panel. It helps, but on cloudy rainy-season days it may not fill the fan.

Is a small solar system worth it just for fans and lights?

If you use them every night and spend on petrol or rechargeables, yes. A small system covers fans, lights, TV and phones together.
