Solar panels for your apartment on Sal: off-grid for T2, T3 and T4

English | Deutsch | Nederlands | Français | Español | Italiano | Português

With an off-grid system your apartment on Sal (Cape Verde, Cabo Verde) runs on its own solar power: from the panels by day and from the battery in the evening and at night. Sal has sun almost every day of the year, so an apartment in Santa Maria, Espargos or Murdeira is ideal for producing your own electricity. The Electra grid only stays connected as emergency backup.

Sun, sea and beach under the palms

Sal is the island for a true sun, sea and beach holiday. You get more than 350 days of sunshine a year, miles of white sandy beaches lined with beach bars, and at Santa Maria you simply walk into the calm, clear sea for a swim. Lying under the palms, a drink on the beach and watching the sun set over the sea: that is a holiday on Sal.

The sea water is around 25 °C on average, and from August to October it is often 28 °C and up to 29 °C. Because it hardly ever rains, the heat is dry: the cooling trade wind keeps it pleasant, never too hot and never cold, and in the evening it cools down a few degrees.

Which system suits your apartment?

In Cape Verde apartments are called T2, T3 or T4: two, three or four bedrooms. The larger the home, the more air conditioners run and the more kilowatt hours you use. That is why there are separate systems:

  • T2: the smallest system, for a two bedroom apartment.
  • T3: more panels and more battery for three bedrooms.
  • T4: for larger apartments and houses with several air conditioners.

For villas and businesses there are larger systems, see solar for hotels and hospitality.

What is included?

  • Solar panels on the roof or a terrace, mounted to resist wind and salt.
  • An inverter that turns it into normal 230 volt power.
  • A battery for the evening and the night.
  • An app on your phone: you always see what your panels produce and how full your battery is.

On an apartment building

For an apartment we look together at where the panels can go: your own part of the roof, a terrace or a roof shared with the other owners. We assess this per project and take care of the installation on Sal.

Why it pays off

With more than 350 days of sunshine a year, a system on Sal produces a lot of power. Power cuts no longer bother you, your air conditioning runs when you need it, and your apartment becomes more attractive to rent out and to sell. See also sizing an off-grid system.
