Who we are

Green Voltage is an energy-sector construction company from Horana. We turn bare land into grid-connected solar farms, raise the poles and string the lines that carry the power, and dig the trenches that keep it underground. One crew, one standard, from the first auger bore to the day the switchyard goes live.

What we do

Four crafts, one crew.

Civil and electrical works for grid-scale solar: from setting out bare land to energising the switchyard. Flat dry-zone fields or terraced hillsides.

How we build a solar farm

Bare land to grid, in nine stages.

01
Set out the land
Survey, clear and peg out every row on bare ground.
02
Bore & pile
Auger-bored holes up to 3 m deep for every footing.
03
Foundations
Cast-in-place footings with anchor bolts set true.
04
Galvanized structures
Steel tables erected and aligned to the sun.
05
Fix the panels
Thousands of modules clamped and torqued.
06
DC wiring
Strings dressed into trays and inverters.
07
LV cable & termination
Cable pulled from the drum, laid and terminated.
08
Transformer & switchyard
Transformer placed, switchyard built.
09
Commissioning
Tested, energised and handed over.
Energised. Handed over, often ahead of schedule.

Projects on the island

33.5 MW and counting.

From the dry zone around Anuradhapura and Trincomalee to the hills of the south: every pin is a farm our crews built. Pick one.

5 MW
5-month build
For DIMO Energy

The complete electrical infrastructure for DIMO Energy's 5 MW plant: panel installation, structures, wiring, testing and commissioning, handed over ahead of schedule. It now generates 9.48 million kWh a year, enough for more than 6,000 homes.
