What Sol1energy does
Sol1energy is a Swedish solar energy installation company operating under the legal entity Sol1 AB (orgnr 559389-1939), a privately held Swedish limited company owned by four holding entities (Förvaltning ACI AB, Faviol AB, J.Tysk AB, and Bellwether AB). The company was formed through the merger (sammanslagning) of several firms with long-standing experience in electrical installation, construction/mounting, and property development, and today consists of more than 20 installers and project managers. Headquartered at Frejgatan 19 in Stockholm, with additional offices in Nacka (Sickla) and Mijas on the Spanish Costa del Sol, Sol1energy serves residential property owners, businesses, and Swedish housing cooperatives (BRF).
The company's core offering is end-to-end solar photovoltaic system installation, supported by integrated feasibility studies (förstudie), a roof design calculator tool, and partnerships with market-leading equipment and inverter providers (cited at up to 99% total efficiency) and Sveabank for customer financing. Around this core, Sol1energy bundles complementary modules: battery energy storage systems (Energilagring) for self-consumption optimization and backup power, and EV charging stations (Laddbox/Laddstolpe) for residential and commercial charging integrated with the solar installation. The underlying technology stack is essentially third-party hardware and partner-developed digital tools rather than proprietary IP.
Sol1energy's commercial model is a consultative, project-based direct sales motion: customers initiate contact via website quote forms or phone, receive a property-specific feasibility study and proposal, and contract the company for installation with optional ongoing maintenance. Revenue is generated primarily through one-time system sales (solar, battery, EV charging) plus maintenance and financing-facilitation services. The company does not disclose pricing publicly, relying on per-project quotes; customers benefit from the Swedish green-tech tax deduction (grön teknik-avdrag). The customer base is fragmented across individual homeowners, businesses, and BRFs in Sweden, with an emerging presence in southern Spain.

Products and services
- Solcellsanläggning (Solar Panel Installation) Solar photovoltaic (PV) panel systems sold and installed for residential and commercial properties in Sweden. Each installation begins with a custom feasibility study (förstudie) showing expected energy generation, followed by design, installation by in-house installers, and optional ongoing maintenance. Systems are designed to lower property owners' energy costs and reduce reliance on grid electricity.
- Energilagring (Battery Energy Storage) Battery energy storage systems (BESS) that integrate with solar panel installations to store excess solar energy for use during evenings, nights, and grid outages. Enables time-of-use bill optimization by purchasing grid electricity when tariffs are cheapest, and provides backup power during grid failures. Eligible for Swedish green tech tax deduction for residential customers.
- Laddbox / Laddstolpe (EV Charging Station) Electric vehicle charging stations (laddbox) and charging poles (laddstolpe) for residential homes, businesses, hotels, shopping centers, and parking facilities. Sold as safer and more efficient alternatives to standard electrical outlets, reducing overheating and fire risk. Can be integrated with solar panel installations to charge EVs with self-produced solar energy, including nighttime charging using stored solar electricity.

Sol1energy competitors and assessment
Company assessmentDirect peers
- Svea Solar: One of Sweden's largest residential and commercial solar installers offering solar panels, battery storage, and EV charging with in-house installation capacity. Direct competitor to Sol1energy across overlapping Swedish customer segments including residential homeowners and BRF.
- Otovo: Norwegian-headquartered solar subscription and installation company operating extensively in Sweden, offering solar panels and batteries to homeowners through both purchase and subscription models. Closely comparable to Sol1energy in Swedish residential and BRF segments with similar product bundling.
- Soltech Energy: Swedish solar energy company providing solar panel installations to residential and commercial customers. Comparable in target market, geography, and integrated solar+battery offering approach to Sol1energy.
Others
- Enphase Energy: Global supplier of microinverters and battery storage systems that Sol1energy likely uses as underlying equipment. Comparable as a technology partner/enabler in the residential solar+battery stack rather than a direct installer competitor.
Broad incumbents
- Fortum: Nordic utility offering solar panel and battery installation services in Sweden and Finland as part of its broader clean energy portfolio. Comparable in customer segments and integrated offering, with scale advantages as a major utility.
- Tesla Energy: Offers residential solar (Solar Roof), Powerwall battery storage, and EV charging solutions directly to homeowners, increasingly competing with traditional installers. Comparable bundled offering though distributed through different go-to-market channels.
- Vattenfall: Swedish state-owned utility offering rooftop solar installation services alongside its broader electricity generation and retail operations. Larger incumbent with solar as one product line among many; competes for the same Swedish residential and BRF customers.
- E.ON Sweden: Major European energy utility with Swedish operations offering solar PV installation, battery storage, and EV charging solutions to residential customers. Competes with Sol1energy through broader brand trust and bundled energy contracts.
- SunPower: US-headquartered solar installer and panel manufacturer with European operations offering residential and commercial solar plus storage. Comparable in technology integration and product positioning though operating at materially larger scale.
Emerging players
- Solar.com: Solar marketplace and installation platform connecting homeowners with vetted installers and offering roof-design calculator tools similar to Sol1energy's online design tool. Comparable in customer acquisition approach and online configurator-enabled sales motion.
