Why solar

Power you can rely on, at a cost you control

Across Timor-Leste, many homes and organisations deal with power cuts, rising electricity costs, or no grid connection at all. A well-designed solar system turns sunlight into dependable electricity — and puts you in control of it.

  • Lower electricity bills — use free solar energy during the day instead of grid power.
  • Keep the lights on during outages — hybrid systems with batteries carry essential loads when the grid goes down.
  • Power where the grid doesn’t reach — off-grid systems bring electricity to farms, schools and remote villages.
  • Less dependence on the grid and generators — clean energy produced on your own roof.

Choosing a system

Grid-tied, hybrid or off-grid?

The right choice depends on your grid connection, your budget and how important backup power is to you. Here is how the three options compare.

How it worksPanels power your building during the day and work alongside the EDTL grid.Panels charge a battery bank while also working with the grid.Panels and batteries supply all your power, with no grid connection.

Battery storage & backup power

Keep essential power running when the grid goes down

A hybrid system stores solar energy in a battery bank so lights, refrigeration, communications and computers keep running through outages and at night. We size the battery to the loads that matter most to you, so you are not paying for capacity you don’t need.

  • Automatic switch-over when the grid fails
  • Battery sized to your essential loads
  • Expandable as your needs grow

Professional installation

Neat, safe and built to last

Every system is installed by our own technicians — with a properly mounted inverter, a protected distribution board, tidy cable runs in conduit, and full testing before handover.
