The company now forecasts sales of €850m ($954m) to €900m, compared to €800-850m expected previously, and earnings before interest and taxes (Ebit) of between €0 and €10m from its previous expectation of a loss of up to €25m.

"SMA has achieved a sustainable turnaround within a short space of time," SMA chief executive Pierre-Pascal Urbon says.

"Due to the SMA Group's extensive transformation in the current fiscal year, we are emerging stronger from the years of structural change in the solar industry and will generate sales growth again this year for the first time since 2010."
