SOLAR PLUS STORAGE BREAKTHROUGH

Half the price in half the time: solar storage innovation harnesses new energy frontier; Brisbane company Redback Technologies, backed by researchers from the University of Queensland, says it has cracked the formula for the most cost-effective solar storage system on the Australian market

Joshua Robertson, 22 February 2016 (The Guardian)

“…[Australia’s Redback Technologies] claims to have harnessed the power of algorithmic software and efficient design to produce [a highly] cost-effective solar storage system…Despite relying on a smaller battery than [Tesla’s] Powerwall – which is widely expected to be the catalyst for rapid growth of the solar storage market this year – Redback says…it would take an average 5.6 years to earn back [its ‘Ouija board’ system’s] $9,000 price tag through electricity bill savings, versus 11 years on the Powerwall’s $15,000 to $17,000 installation cost…[Redback is] less concerned with batteries as the cutting edge of the household solar energy market as…[with tackling the problem of how households can consume more than 25-30% of the power from] their solar panels…The Powerwall, with its Lithium battery, would take ‘self-consumption’ to 57%...The Ouija system would better that at 61% and ‘about a third less in cost’ than the Powerwall…” click here for more
