The rise of rooftop solar in Australia has been extraordinary.
In 2009, there were fewer than 100,000 rooftop solar systems in Australia. Now, that number is more like 1,000,000. Rising electricity prices, falling equipment costs, higher levels of environmental awareness and large government subsidies have created the conditions for explosive growth.
Like a child moving into the more complicated world of adolescence, the rooftop solar industry is growing up. As a result, some of the rules governing its behaviour will also have to evolve as support is gradually removed and the industry interacts with the established power industry on a more even footing. This is not a bad thing – it marks the sector’s coming of age.
A good first step was the Victorian government’s decision to decrease the ‘feed-in tariff’ – the rate paid to households for every kilowatt-hour of electricity they export to the grid. On January 1 this year, the feed-in tariff was cut from 25 to 8 cents. This may seem like an excessive cut, but the 25 cent tariff was too high to be sustained with more and more systems being installed, and the impact has been cushioned by lower prices for photovoltaic cells. Critically too, this change only applies to new installations, so it does not undermine the support for customers who got in early to install solar panels when the upfront installation costs were higher.
