Types of Transformer use in Solar Power Plant
Inverter transformers are used in solar parks for stepping up the AC voltage output (208-690 V) from solar inverters (rating 500-2000 kVA) to MV voltages (11-33 kV) to feed the collector transformer. Transformer ratings up
Beyond Tokelau''s 100% solar: add wind power!
Tokelau was the first nation in the world to go 100% solar in 2012. Now the country is aiming to keep its fully renewable energy status in the future using wind power. This is going to reduce the need for diesel fuel backup in prolonged times of cloudy weather, and when the solar cell system needs maintenance.

"Solar Power in Tokelau" includes the following features that help develop the reading behaviours expected at Gold. This report highlights the world-first achievement of Tokelau in using renewable energy sources (solar energy and coconut oil) for all its electricity. It explains why Tokelau decided to switch from using fossil
Tokelau – the world''s first solar power sufficient nation
Tokelau – the world''s first solar power sufficient nation. Tokelau, an island nation in the South Pacific, is now completely able to support itself with solar energy. Elly Earls met Joseph Mayhew of the New Zealand Aid Programme to find out how this tiny collection of atolls has become almost 100% self-sufficient in less than 12 months.
Solar Project
Solar Array''s seen on the three tiny islands of Tokelau to completely produce solar power energy. The renewable energy system comprising of solar panels, storage batteries and generators running on biofuel derived from coconut will generate enough electricity to meet 150% of the islands'' power demand.

Tokelau becomes the world''s first 100% solar powered country
Its land area covers 10 square kilometres and it is located north of Samoa, reachable only by boat. Traditionally, all three atolls have relied almost exclusively on diesel generators for their electricity needs, but it has recently become the only country in the world to be fully powered by solar power.

6 FAQs about [Tokelau transformer for solar power plant]
Can a solar array power Tokelau?
Solar Array’s seen on the three tiny islands of Tokelau to completely produce solar power energy. The renewable energy system comprising of solar panels, storage batteries and generators running on biofuel derived from coconut will generate enough electricity to meet 150% of the islands’ power demand.
Could Tokelau be the world's first renewable nation?
Solar power plants and coconut biofuel-powered generators switched on in Tokelau has made the islands the world’s first truly renewable nation.’ Imagine a place where the only energy to be found is clean, reliable solar power. Solar Array’s seen on the three tiny islands of Tokelau to completely produce solar power energy.
How much electricity does a solar system provide in Tokelau?
Each system alone is among the largest off-grid solar power systems in the world, and together they are capable of providing 150% of current electricity demand in Tokelau, a much higher amount than the 90% that was originally planned for.
Why did Tokelau switch to solar?
Yet despite the challenges involved in installing comprehensive solar systems in such a remote location, switching to solar was absolutely crucial for the tiny collection of islands. "Tokelau’s atolls are low-lying and especially susceptible to the adverse effects of climate change," Mayhew stressed.
How to choose a step-up transformer in a PV plant?
In general, the selection of the step-up transformer in a PV plant is a quite complex task as several variables depending on the transformer rated power must be taken into account as: initial cost of the system, energy losses due to transformer efficiency, energy storage system efficiency and possible plant disconnections due to grid instability.
How much does a diesel generator cost in Tokelau?
Indeed, until recently, diesel generators were burning around 200 litres of fuel daily on each atoll, meaning more than 2,000 barrels of diesel were used to generate electricity in Tokelau each year, costing more than $1m NZD.
