Solar System on Fakaofo Atoll (Tokelau) Construction Underway

This week marked the first week in the construction of Fakaofo Atoll's solar power system.  The Tokelau Renewable Energy Project (TREP) will help transition the three Atoll's of Tokelau from fossil fuel power generation to be the first solar powered nation.  A total of 4096 solar panels, 392 inverters, and 1344 batteries will be installed across the 3 atolls.

Powersmart solar's engineers arrived early last week and have had a productive first week. 

In the image to the left a jig is used to accurately line up the array frame fixing bolts. M12 stainless steel threaded is epoxied into the concrete foundations. The array frames and foundations are designed to survive cyclone force winds of up to 230 km/h.

Next up is filling the batteries with acid and setting up the first charge. Each battery weighs 150 kg making it a challenge to put in place. There is also a restriction that the batteries cannot be tilted more than 10 degrees meaning that jigs needed to be manufactured to lift them in place.

We are having a relaxing weekend enjoying the generosity of the tokelauans and are looking forward to next week!
