What Soldags does
Soldags i Sverige AB, doing business as Soldags, was a Swedish residential solar energy installation company that operated as a wholly-owned subsidiary of Soltech Energy Sweden AB (publ), a publicly traded parent on the Nasdaq First North Growth Market. Founded in 2017 and headquartered in Stockholm, the company targeted Swedish residential end-customers with a bundled offering that combined rooftop solar panel installation, electricity trading agreements (elhandelsavtal) for solar power producers, and app-based energy monitoring via a smart control unit branded "Soltech Core" and managed by partner Enequi AB. The company sat within the broader Soltech Group's marketing ecosystem and operated with a headcount in the 11–50 range.
The company's revenue model was anchored on residential solar installation contracts and ancillary electricity-trading arrangements rather than disclosed subscription or licensing fees; no public pricing or revenue figures were disclosed for Soldags specifically. Its go-to-market relied on direct-to-consumer installation services in Sweden and the brand association with the Soltech Group. The underlying technology stack centered on solar panel system integration and the Soltech Core control unit, which connected installations for improved energy economics; no proprietary patents, certifications, or AI/ML components are documented.
All operations ceased when the parent company's board determined on January 23, 2026 that continued operation of Soldags was not economically sustainable, resulting in the subsidiary being declared bankrupt. The bankruptcy estate (konkursbo) is administered by trustee Jenny Hildén of Wahlton Advokatbyrå; the estate cannot honor installation warranties, continue support contracts, or fulfill pending installations, and customers have been directed to seek alternative service providers or file claims against the estate.

Soldags competitors and assessment
Company assessmentDirect peers
- Otovo: Norwegian-headquartered residential solar installer and subscription provider operating across the Nordics. Offers a comparable bundled rooftop solar + electricity agreement model to homeowners, making it a direct competitor to Soldags in the Nordic consumer market.
- SunRoof: Sweden/Poland-based residential and commercial solar roof installer with proprietary integrated roof-solar systems. Targets the same Nordic residential segment as Soldags with a differentiated full-roof product offering.
- Svea Solar: Swedish residential and commercial solar installer. Was acquired by Soltech Energy in 2024, then later divested, and has historically competed directly with Soldags in the Swedish rooftop solar market.
- Sesol (Soltech Home): Sister brand under the same Soltech Energy parent, offering residential solar and consumer-facing energy solutions in Sweden. The Soltech Group is explicitly redirecting Soldags customers to Sesol/Soltech Home, making it the closest functional substitute.
Broad incumbents
- E.ON Sverige: Swedish arm of European utility E.ON, offering residential solar, electricity supply, and energy services. Competes with Soldags in the consumer solar market as part of a diversified utility offering.
- Vattenfall: Large Nordic utility offering residential solar solutions alongside its core electricity retail business in Sweden. A broad incumbent that competes with Soldags for consumer solar customers as part of a much wider energy portfolio.
- Fortum: Nordic utility with growing residential solar and energy services offerings across Sweden and the Nordics. Provides overlapping capabilities to Soldags but as part of a much broader energy portfolio.
Others
- Enequi AB: Technology partner that managed the Soltech Core control unit for Soldags customers. Not a direct competitor but an ecosystem participant whose platform integration was central to Soldags' differentiated offering.
