Australia is a world leader in the uptake of rooftop solar and our technologies are leading the way.
Efficiency gains, economies of scale, wider public acceptance, more product variety and increasing capacity continue to lower the cost of solar production. The rapid adoption and subsequent price reduction of solar panels resulted in an astounding 18-fold increase in uptake from 2010 to 2020, accompanied by an 80% decrease in costs. Once installed, solar and wind both offer cost-effective electricity generation, require minimal maintenance and do not create pollution or greenhouse gas emissions.
PV panels (or solar panels) use photovoltaic technology to convert sunlight into electricity. They are scalable to the power needs of a home, business, factory or powerplant. Multiple panels, combined with an inverter, are called a solar system, generating direct current (DC) electricity and converting it to alternating current (AC) electricity for safe use in standard electricity circuits. Systems can be installed on the ground, wall or rooftop, and can be fixed in place or use a solar tracker to follow the sun across the sky. They can be thin enough to roll up like a poster and deployed so fast that a 1MW solar farm can be rolled out in a day.
Australian innovations continue to discover more effective ways to build, utilise and deploy solar technology, and make use of our abundant sunshine.
Robust and relocatable, the 5B Maverick is a rapidly deployable, scalable, prefabricated solar solution. With reduced onsite labour, high energy density and rated for use in Wind Region D and C4 corrosion class environments, the 5B Maverick is designed for challenging, remote, and land constrained projects.
You don't need a roof to have solar. Allume allows occupants of multi-tenant buildings to benefit from rooftop solar. They install solar and batteries behind the meter in apartment blocks and use software to enable the energy to be shared.
Borroloola's Ngardara Solar Microgrid Project
This remote community will soon have clean and affordable energy. Borroloola's Ngardara NT community is building a 3.2 MW microgrid using solar and batteries. This will replace their diesel generator and reduce their dependance on transmission lines.
Central Queensland Power
This joint venture is driving the decarbonisation of heavy industry in Gladstone and the wider Central Queensland region. Energy Estate and RES are developing a portfolio of wind, solar and BESS projects with a capacity of over 2GW.
Coolsheet uses the heat from solar panels, which would otherwise be wasted, to heat pumped water. This process also reduces the operating temperature of solar panels, which means they generate more power.
The ‘electric superhighway' proposes a high voltage transmission link between the Darwin-Katherine and Alice Springs electricity networks. This connection would use community generated solar energy to cool homes, create jobs, and empower Indigenous Australians.
Green Energy Manufacturing (GEM) Centre
Powered by renewable energy, the GEM project intends to create a pollution-free manufacturing hub. Their objective is to produce more than 200,000 tonnes of green hydrogen annually, with a plan to increase to 15Mt CO2e annually by 2030.
The HyNQ Clean Energy Project is a green hydrogen, freshwater and renewable electricity production project at Abbot Point, North Queensland. The project will dramatically reduce the cost of green hydrogen and support local green jobs in the Bowen Basin.
Kardinia Energy manufactures Printed Solar, a low-cost, lightweight, flexible solar technology that is fully recyclable. Utilizing highly abundant semiconducting materials, they print solar cells on recycled PET plastic. Kardinia Energy is scaling its manufacturing in the Hunter Region.
Keppel Prince is a large scale manufacturer and installer of Wind Farm and Solar infrastructure. They have worked on some of the largest wind farms in Australia and delivered over 10MW of rooftop solar.
Magellan Power design and produce durable power electronics for the harsh conditions that Australian, homes, mining and industry face. Their range includes AC and DC power systems, inverters, UPS, and energy storage solutions.
Okra Solar is a technology company focused on providing affordable, reliable, and sustainable energy access to people living off-grid. Their vision is to leverage energy access to create opportunities for the underserved.
Pilbara Solar empowers First Nations people to lead utility-scale renewable energy projects. For example, the Junja project will build a 10MW solar farm to reduce costly and carbon-intensive diesel generation and create economic benefits for the Jinparinya community.
Reposit supplies domestic solar systems (panels, inverter, battery, software), across Australia. They guarantee zero electricity bills for households.
Solahart offers solar power, solar hot water, heat pumps, battery storage and solar-smart electric water heaters for residential and commercial settings. With over 70 years of experience in solar, Solahart has installed over a million systems.
Solar Analytics evaluates the performance of solar systems and helps people optimise their energy usage. Their software allows residential consumers to get the most out of solar energy and batteries, thereby maximising the decarbonisation effect.
Solpod makes and supplies relocatable "Solar Pods" in Victoria. Solpods are pre-fabricated frames holding 10 solar PV modules which can be lifted from a crane and fixed to the roof in 10 minutes, allowing businesses that rent their premises to easily move their solar panels if needed.
Thanks to Australian innovation, solar cells no longer require silver to be produced. SunDrive invented and now manufactures solar cells that use copper instead of silver, which is half the price of silver and significantly more available.
Tindo Solar's solar panels are manufactured and designed in Australia for Australian conditions. Operating in Adelaide, they produce technologically advanced and high quality solar panels for use in a variety of settings.
Monitoring hardware, cloud tools and hardware analytics are essential to optimising our electricity use. Wattwatchers creates devices and digital platforms that provide intelligent, real-time energy management for homes and small businesses, commercial and industrial buildings, and utility use cases.
