Perth Gets First House Powered Almost By 100 Percent Solar

A Hilton home has been adjudged the first in Perth to utilize the Sunlight to produce all of its electricity by storing the energy in batteries and still connected to the electricity grid.

The house makes use of solar for 97% of its electricity demands and also reduce extra supply onto the electricity grid, in what could become an established concept in the future.Environmental scientist Josh Byrne constructed the house in Perth’s southern region 2-years gone with a 10-star energy rating.

Mr Byrne indicated that when he first designed the home, he never thought batteries would be less expensive enough to consider, but today they are.

“For a unit like this you are looking at around about $12,000, so for our power use patterns the pay-back time is somewhere between eight to 10 years,” he stated.

“But the expectation is that these systems will come down as volume of production and competition increases, but also as power prices continue to go up we will start to see the pay-back time for these systems being much more attractive.”

Remaining connected to the territory’s electricity network helps the house to also accumulate energy off if it demands a top-up on a cloudy day or return energy into the electricity grid. Curtin University researchers are investigating into the project to see of the scheme can be extended all over the network to levelise the peaks and troughs of solar energy on the electricity grid.

But Curtin University’s Jemma Green said batteries gave huge importance for the network.

“The battery is going to reduce the upload of electricity during daylight hours when the Sun is shining,” Ms Green said.

“Perhaps we could use the battery at night for household consumption, and if there is any excess it can be used as load balancing to smooth out peak demand for electricity.”

Energy Minister Mike Nahan has indicated he would support the plan.

Ms Green said the survey would also aim to address public policy.

“The research is looking at what are the implications for consumers in installing batteries in their houses and apartments,” she said.””For property developers, I think, it is quite an exciting proposition to put solar and batteries on strata to avoid having to do head work upgrades of substations and transformers.”
