What Gaia Solar does

Gaia Solar is a Danish solar photovoltaic (PV) solutions provider operating under Sunfactor ApS, following Sunfactor's April 2019 acquisition of Gaia Solar v/Solaropti. The company is based in Hvidovre, Denmark, and employs 11-50 people serving both residential and commercial customers across Denmark. Its product portfolio spans solar panels (standard and custom building-integrated variants from BISOL, Axitec, and a TÜV-certified German partner), inverters (primarily Fronius, with Goodwe, SMA, and Delta alternatives), mounting systems (Wasi primary, Schletter and Profiness secondary), and lithium-ion battery storage (Fronius with BYD and SolarWatt MyReserve). A specialty offering is Solcelletegl (Solar Roof Tiles), building-integrated PV tiles replacing traditional roof tiles.

The business operates a sales-led, project-based go-to-market model through direct outreach, website inquiries, phone (+45 81746799), and email ([email protected]), with no publicly disclosed pricing. Revenue is generated primarily through one-time sales and installation of complete PV systems for residential, commercial, agricultural, and municipal customers, supplemented by professional services revenue from consulting, design, technical/regulatory advisory, and ongoing maintenance and repair. As a Fronius service partner, the company performs fault diagnosis and repair on most solar installations regardless of original installer. The customer mix spans private homeowners and businesses/agriculture as primary segments, with municipalities, public sector, and housing associations as secondary segments; reference projects include Greve Gymnasium (~50% of electricity consumption covered), a 525 kWp farm installation in Fyn, and 600+ kWp delivered to Allerød Municipality.
