Some 35 cyclone-battered properties which remain without power three months after Cyclone Seroja will receive standalone power systems to help them turn on the lights.

The cyclone caused more devastation than Western Power has ever seen, with more than 4,000 power poles down over an area about half the size of Victoria.

The extent of the destruction has seen Western Power fast-track plans to introduce standalone power systems — powered by solar panels, along with a backup generator — to individual properties in the region.

The corporation plans to install a total of 6,000 standalone power systems to Midwest and South West landowners over the next 20 years. 

Of the 6,000 systems, some 98 will be installed this year, including 35 in the Midwest.

Reliant on generators

Among those set to receive a unit is farmer Brady Green, of Chapman Valley, who is expecting his new system to arrive in August.

Mr Green and his family woke up the day after the cyclone to find their house relatively intact, but their farming sheds, silos and machinery badly damaged.

Since then, they've relied on generators to power their house and farm sheds.

"It was right at the start of seeding, we had to accommodate people here, so we got hold of gen [generator] sets as soon as we could," Mr Green said.

Fast-tracking the rollout

Within a week of the cyclone, Western Power had restored power to 85 per cent of the 33,000 affected properties.

But properties at the end of power lines remained powerless.

Western Power executive of asset operations Sam Barbaro said it made sense to fast-track the rollout of standalone power systems.

While Western power is yet to put an exact figure on savings, it expects the standalone power systems to save millions by avoiding the need to repair and maintain remote power lines.

The standalone power units are being produced at Hybrid Systems Australia where executive director Mike Hall is rushing to keep up with demand.

So popular are the renewable energy providers' products that it is constructing the world's biggest standalone power production facility — a 16,000 square metre site in Perth Airport's industrial precinct.

For Mr Green the installation of standalone power is a win-win.

"There's a lot of inconveniences with power lines across paddocks — it's dangerous as the lines go across our yard so the idea of none of that being here is pretty exciting," Mr Green said.

"And when you think about burning coal in Collie to fire up our ovens it's crazy, so it's quite exciting to be moving onto solar."
