Business has boomed for more than three in four solar companies, powered by the battery rebate, but almost as many fear a bust when government support ends.

Some solar installation firms are faring substantially better than others, a study has found, with smaller operators less likely to reap financial benefits than their larger rivals.

Software firm Pylon issued the findings on Wednesday in research that surveyed hundreds of solar and battery companies on the frontline of the consumer energy transition.

The study comes less than two weeks after Australian households and businesses passed a renewable energy milestone, installing more than 500,000 batteries, and four months after changes to the Cheaper Home Batteries Program.

The inaugural Pylon State of Solar Business 2026 survey polled representatives from 345 solar installation companies across Australia about the industry, rebates and concerns.
