What Giga.Green does
GIGA.GREEN GmbH is a Berlin-based Solar-as-a-Service provider founded in 2018 by Sebastian Schmidt and Wolfgang Röbig. The company plans, finances, installs, and operates decentralized photovoltaic (PV) systems — rooftop, carport, and open-space deployments — on commercial properties under a zero-upfront-investment model. Customers lease their roof or land to GIGA.GREEN in exchange for advance lease payments and then purchase the generated electricity at long-term fixed, low prices via onsite Power Purchase Agreements (PPAs), with optional battery storage and EV charging infrastructure bundled at no additional cost. The company claims customers save 50–60% on electricity costs compared to market rates and become "profitable from day one" versus the typical 6–8-year payback for purchased systems.
The business model generates two recurring revenue streams: (1) long-duration electricity sales through PPAs (subscription/recurring), and (2) roof/land leasing income (managed services). GIGA.GREEN employs 11–50 people and sells primarily through direct enterprise field sales, targeting large corporations with multi-site networks, SMEs with up to 10 locations, and commercial real estate owners/asset managers. The company is funded by a €25M equity investment from Japanese sustainability investor Ichigo Inc. (July 2024, 24.39% stake) and a €30M debt facility from Kommunalkredit Austria AG (July 2025), and has signed strategic partnerships with Redevco (36 retail park sites), eliso GmbH (EV charging JV), and enterprise customers including BAUHAUS, Rhenus Logistik, TotalEnergies, REPO, Euromaster, and FSV Frankfurt 1899. The stated corporate mission is to save one gigaton of CO2 with customers through decentralized solar deployment across Germany.

Giga.Green competitors and assessment
Company assessmentDirect peers
- Enpal: Germany's largest residential solar-as-a-service provider. Same zero-upfront PPA/lease model for end customers, but focused on residential rooftops rather than commercial; comparable capital-intensive, subscription-based model and German market focus.
- 1Komma5°: German distributed energy company offering solar, heat pumps, EV charging, and electricity contracts to homeowners. Directly comparable Solar-as-a-Service business model with expansion into energy-as-a-service; recent scaling into commercial segments creates overlap with GIGA.GREEN's large-corp offering.
- Zolar: German online solar platform facilitating PV installations for homeowners and small businesses. Similar intermediary/financing-led model with PPA-adjacent offerings; smaller-scale and more residential, but comparable customer-acquisition and partner-network approach.
- Lichtblick: German decentralized energy provider offering ZuhauseStrom (home electricity from renewable sources) and increasingly distributed generation. Comparable focus on customer-facing renewable energy products and subscription-style contracts in Germany.
- Solarwatt: German solar panel manufacturer and rooftop PV installer offering complete systems with financing and battery storage for residential and commercial customers. Comparable end-to-end solar delivery model in Germany with growing commercial rooftop focus.
- BELECTRIC Solar & Battery: Germany-based EPC and O&M provider for utility-scale and commercial solar plus storage. Overlaps with GIGA.GREEN on German PV deployment and complex rooftop projects, but more utility-scale and less specialized in the PPA/lease commercial proposition.
Broad incumbents
- E.ON Solar Solutions: Major German utility's distributed solar division offering rooftop PV and storage to commercial customers. Broader portfolio (grid, networks, retail energy) and deeper balance sheet create overlap with GIGA.GREEN's commercial PPA offering, but E.ON is not specialized in complex multi-tenant retail rooftops.
- EnBW Solar / EnBW Solutions: Large German utility with significant commercial solar operations and PPA offerings for enterprise customers. Comparable commercial rooftop and PPA business but part of broader energy portfolio; larger scale and lower cost of capital represent competitive threat.
- Sunrun: US leader in residential solar-as-a-service with subscription/leasing model. Comparable asset-owning, subscription-based revenue model with long-term PPAs and lease payments; differs by being residential-focused and US-only, but offers a comparable template for commercial scaling.
Emerging players
- ChargeGuru: European EV charging solutions provider that often bundles charging with solar/PV offers for businesses. Comparable as an emerging player offering integrated solar+charging propositions to commercial customers in Europe, overlapping with GIGA.GREEN's eliso JV value proposition.
