What Sunbooster does
Sunbooster (legally SUNBOOSTER GmbH in Austria, with operational ties to Bordeaux, France) is a private solar technology company founded in 2010 that develops residential photovoltaic hardware. Its core product is a proprietary rainwater-based cooling system for solar panels, claimed to improve photovoltaic performance by approximately 10%. The company has subsequently expanded its portfolio to include the Vertical+ fence-mounted PV system for vertical-surface installations and IoT-integrated photovoltaic balcony storage units designed for residential self-consumption optimization. Sunbooster also operates the sunbooster.fr French-language blog, which publishes educational content on photovoltaics, inverters, kWh management, and related electrical topics, functioning as a content-led inbound channel.
The company monetizes primarily through hardware sales across three product lines, targeting residential solar homeowners and properties with limited or unsuitable roof space for traditional installations. In December 2021, Sunbooster raised €4.7 million (approximately $5.3 million) led by AQUITI Gestion, with participation from Altor and Expanso Capital, to accelerate commercialization and international expansion. In March 2026, the company demonstrated a joint IoT battery-charging optimization solution with Acceleronix at MWC Barcelona and launched the Vertical+ fence-mounted PV system. The company maintains a very lean operating footprint of 1-10 employees and has not disclosed customer counts, revenue figures, or institutional ownership beyond the 2021 investor syndicate. Gregory Boutteau is identified as president and co-founder.
