Assemblin Solar

What Assemblin Solar does

Assemblin Solar AB is a Sweden-based, full-service solar photovoltaic (PV) installer established in 2021 as a dedicated business unit of the Assemblin Caverion Group, building on solar installation work the parent has performed since 2014. The company designs, sells, and installs grid-connected solar PV systems — paired with battery energy storage — across five customer segments: residential villas and summer houses, commercial enterprises (företag), housing cooperatives (BRF), agricultural properties (lantbruk), and ground-mounted installations (markanläggning). Reference customers span real estate (Stena Fastigheter), municipal government (Göteborgs Stad, Varbergs Stadshus), higher education (Borås Högskola), manufacturing (Tryckta AB, 526.24 kW), agriculture (JSM Ridhuset Valinge, 375 kW), and religious institutions (Apelvikshöjds Kyrka).

The technical stack combines premium AIKO full-black solar panels with Ferroamp's Swedish EnergyHub energy management platform, which delivers phase balancing, integrated storage control, real-time app-based monitoring, and island operation (ö-drift) for power-outage protection. Standard and hybrid inverters are sourced from Sungrow, Huawei, Sigenergy, and Growatt, allowing the system to operate with or without a connected battery and supporting future storage upgrades. With over 2,000 in-house qualified electricians distributed nationwide, Assemblin Solar self-performs installation and handles permits, grid connection applications, and ongoing service — a structural differentiator versus subcontractor-dependent competitors.

The business model generates revenue through three streams: (1) one-time installation sales of complete PV systems with custom quotes sized to roof/load, supported by 36-month interest-free financing via Wasa Kredit; (2) recurring annual service contracts (Basic from 3,000 SEK, Plus from 4,500 SEK) covering monitoring, remote troubleshooting, and on-site service; and (3) transaction-based commissions from partner financing and electricity contracts (Bixia: 4-year fee discount and renewable supply at spot + 0.05 SEK/kWh export rate; Elvy: bundled solar+battery+heat pump subscription). Go-to-market is sales-led, using website-driven free consultation booking for residential customers and on-premise field sales with ROI calculations for commercial/agricultural/BRF prospects, reinforced by Sigenergy roadshow events and paid social campaigns across Facebook, Instagram, and LinkedIn.

Recent moves6 records

Expansion highlights6 records

Direct peers

• Otovo: Otovo is a Norway-headquartered, publicly listed (Oslo Børs) residential solar subscription and installation company with active Swedish operations. It competes directly via a tech-enabled, standardized digital sales model—a structural contrast to Assemblin Solar's field-sales-led approach.
• Soltech Energy Sweden: Soltech Energy is a Swedish solar energy company listed on Nasdaq First North that designs, installs, and finances solar PV solutions for residential, commercial, and agricultural customers. It is a direct Swedish-market peer across overlapping customer segments.
• Svea Solar: Svea Solar is one of Sweden's largest residential and commercial solar PV installers, offering panels, battery storage, and EV charging across the Nordic market. It directly competes with Assemblin Solar on villa, BRF, and commercial segments in Sweden with comparable full-service positioning.

Emerging players

• Ferroamp: Ferroamp is a Swedish-listed energy technology company providing the EnergyHub system that Assemblin Solar integrates into its installations. While a technology partner, Ferroamp also delivers solar-plus-storage solutions to end customers, making it a partial competitor in the Swedish energy management space.

Broad incumbents

• IKEA (Solselskapet / Svea Solar partnership): IKEA offers Swedish customers solar panel solutions through a partnership model with installation providers, leveraging its massive retail footprint and brand. It represents a broad-channel competitor accessing the same residential solar market through non-traditional retail distribution.
• Vattenfall: Vattenfall is the Swedish state-owned utility offering rooftop solar PV installations and electricity contracts to Swedish residential and commercial customers. It is a broad incumbent that overlaps with Assemblin Solar in the Sweden distributed solar market with the backing of a major utility.
• Eltel Group: Eltel is a Nordic infrastructure service company specializing in power, communication, and electrical networks across Sweden, Norway, Finland, and Denmark. As a broad Nordic infrastructure incumbent with electrical installation capabilities, it represents a broader competitor that could expand into distributed solar installations.
• E.ON Sverige: E.ON Sverige is a large European utility with Swedish operations offering solar PV installations, electricity supply, and energy services to residential and commercial customers. As a broad incumbent with utility-scale resources, it competes in the same Sweden solar market.

Regional players

• OneCo (formerly Caverion Sverige installations): OneCo is a Nordic technical installation and infrastructure services company operating across Norway and Sweden with electrical and renewable energy capabilities. As a peer within the broader Nordic installation services landscape (and historically linked to the Caverion side of the parent group), it represents an adjacent infrastructure services peer with solar capability.
• Norsk Solar: Norsk Solar is a Norwegian utility-scale and commercial solar EPC company with Nordic regional operations. While primarily Norwegian, it serves the broader Nordic market with comparable turnkey solar EPC services, representing a regional peer rather than direct Sweden competitor.
