**[1. Is it worth getting solar panels on my house?](https://solartrustcentre.com.au/is-it-worth-getting-solar-panels-on-my-house/)**

Australians usually spend at least $4,000 on panels, inverters, batteries and optimisers. A large house may need equipment that costs over $10,000. Does it really make sense to spend this much money? It’s important to discover and evaluate all of the potential benefits.

**[2. Under new asset management — Australia’s utility-scale solar farms](https://www.pv-magazine-australia.com/2019/06/30/under-new-asset-management-australias-utility-scale-solar-farms/)**

Year two of Australia’s utility-scale solar boom and the first wave of defects liability periods is rolling to an end, providing new opportunities for long-term maintenance and optimisation of plant performance. This week the Smart Energy Council and SolarPlaza raised a conference in the name of Solar Asset Management, to help address risks and responsibilities for these and future solar farming.

**[3. Australia’s potential rooftop solar output could exceed grid demand: expert analysis](https://www.energymatters.com.au/renewable-news/australias-potential-rooftop-solar-output/)**

The potential rooftop solar energy output of Australia is greater than the amount of electricity we consume through the national grid each year.

**[4. UNSW enabling terawatts of solar power](https://www.pv-magazine-australia.com/2019/06/24/long-read-unsw-enabling-terawatts-of-solar-power/)**

The influence of the University of New South Wales (UNSW) School of Photovoltaics and Renewable Energy Engineering spreads over the horizon like rays of sunlight through a coal haze. Its researchers are confidently working towards the time when terawatts of solar PV power people’s aspirations from Uttar Pradesh to Perth and Pennsylvania.

**[5. W.A. gold miner claims Australian first with wind, solar and battery microgrid](https://onestepoffthegrid.com.au/w-a-gold-miner-claims-australia-first-with-wind-solar-and-battery-microgrid/)**

A hybrid wind, solar, battery and gas microgrid being built to power a Western Australian gold mine has won backing from the Australian Renewable Energy Agency.

**[6. Green hydrogen costs may fall as quickly as solar, but Australia still needs some luck](https://reneweconomy.com.au/green-hydrogen-costs-may-fall-as-quickly-as-solar-but-australia-still-needs-some-luck-26685/)**

The cost of electrolysers to create hydrogen are likely to fall by more than 70 per cent over the next decade – matching the recent dramatic cost falls of solar PV and battery storage – but it may still not be enough to provide Australia with a breakthrough in green hydrogen exports.

**[7. Lightyear One solar car promises free motoring — with a catch](https://www.news.com.au/technology/innovation/motoring/motoring-news/lightyear-one-solar-car-promises-free-motoring-with-a-catch/news-story/6e7a1e04bc1d9a031e403be869c9357f)**

There’s a bit of buzz around the new Lightyear electric car, which claims to have solved the problem of range anxiety along with dependence on power infrastructure.
