W.A. residential solar PPA trial a big hit with home buyers

A Western Australian housing development offering drastically reduced daytime power costs through a residential solar PPA has been a resounding success, with 90 per cent of home buyers opting in to the deal.

As we reported here, the innovative scheme was launched just over a year ago in a trial  at Yolk Property Group’s Amble Estate in Girrawheen – a mix of 129 “affordable and highly sustainable” houses, apartments and townhouses.

Designed in conjunction with solar installer and electricity retailer Infinite Energy, the deal offered home buyers who opted in to a “sustainable living package” a rooftop solar system of between around 3.8 – 4.8kW, installed at no upfront cost.

Instead, the household would enter into a 10-year solar PPA direct with Infinite Energy, giving that company ownership and maintenance responsibilities for the solar system for the term of the contract.

In return, the home owner gets access to daytime solar power at a guaranteed discounted rate of net 40 per cent less than the A1 grid tariff offered by WA government-owned retailer, Synergy.

In a statement on Wednesday, Infinite Energy said that 37 of 42 purchasers had chosen to opt in to the PPA, which it described as the first large-scale solar PPA to be rolled out at a residential community in Australia.
