How to store energy has become as important a challenge as how to generate it. The types of batteries that power our electronic devices or vehicles are tried and tested, but they’re not suitable for really large-scale energy storage – the sort of batteries that can power whole communities, key emergency services and critical infrastructure.
Prices in November have dropped to one of the lowest levels since 2012 placing solar power at an average of $1.70/W. 1.5kW, 2kW, 3kW, 4kW and 5kW solar power systems have dropped to record low prices, this could be caused by the sudden high demand. It seems like everywhere one looks there is talk of solar power be it on the TV or social media.
The average solar PV system price came down to $1.79 per watt this month, coming close to the low of $1.76/W set in March of this year.
There was a fall in the price of solar power systems between August and September with large variations between solar prices for the smaller size systems 1-2kW. Brisbane saw a rise in price for the top end components while basic models changed little.
