Rooftop photovoltaic and energy storage

How many rooftop PV units were installed in Australia in 2024?

In the second half of 2024 there were 159,011 rooftop PV units installed across Australia. Rooftop PV continues to be a key and growing contributor to the nation’s energy mix, with a generation share of 12.4% for all of 2024 (up from 11.2% in 2023 and 6.5% in 2020). The total installed capacity of rooftop PV for 2024 was 3 GW from 300,375 units.

Where do rooftop solar and battery installation data come from?

The rooftop solar and battery installation data featured in this report is sourced from our data partner for these Rooftop Solar and Storage reports, SunWiz, with supplementary data from Green Energy Markets – the Clean Energy Council’s data partner for our annual Clean Energy Australia report – referenced in some instances.

How many batteries are installed on rooftop PV systems in Australia?

Battery attachments to rooftop PV systems continues to trend upwards, with 185,798 units now installed across Australia. The second half of 2024 saw 45,233 units sold – 55 per cent more than the same time 12 months ago.

How much electricity can a rooftop solar system generate a year?

It then calculates that if every suitable roof was used, rooftop solar could generate 19,500 TWh of electricity per year, allowing for fossil fuel-based electricity to be replaced almost entirely, when coupled with load shifting and battery-electric storage.

How big is rooftop PV in 2024?

Rooftop PV continues to be a key and growing contributor to the nation’s energy mix, with a generation share of 12.4% for all of 2024 (up from 11.2% in 2023 and 6.5% in 2020). The total installed capacity of rooftop PV for 2024 was 3 GW from 300,375 units. This complements the 1.1 GW worth of commissioned large-scale generation projects over the

Are rooftop PV systems a climate mitigation tool?

The paper identified East Asia as having the highest potential for rooftop PV systems as a climate change mitigation tool, citing high carbon intensity and large building stocks.
