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.

What we do
Solar energy solutions for homes, businesses and institutions
From a single family home to a school, clinic or remote community, we design each system around real energy use.

Residential solar
Grid-tied, hybrid and off-grid systems for homes, with optional battery backup for outages.

Commercial & institutional
Reliable power for offices, schools, clinics, NGOs and industrial buildings.

Community & off-grid
Simple, robust systems for farms, rural households and villages beyond the grid.

Technical & advisory
Field surveys, site verification and local coordination for consultants, donors and government partners.
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.
| Grid-tied | Hybrid (solar + battery) | Off-grid | |
|---|---|---|---|
| How it works | Panels 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. |
| Power during outages | No — switches off with the grid for safety | Yes — selected circuits keep running from the battery | Yes — fully independent |
| Battery storage | Not required | Included | Included |
| Best for | Lowering daytime electricity bills | Homes and facilities with frequent outages or night-time needs | Remote sites the grid does not reach |

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.
