What Zolar does

Zolar operates a digital marketplace, branded as the zolar Marketplace, that connects renewable energy installers (solar PV, heat pumps, battery storage) in Germany and the Netherlands with regional project leads, and additionally allows lead providers and subcontractors to monetize lead flow or overflow capacity. The platform is built around a self-service model: installers create an account at auth.sollit.com, draw service areas on a map, select trades, and begin claiming leads the same day without onboarding or IT involvement. Core product features include regional lead filtering across solar, heat pump and battery requests, an Autobuy automation engine that claims matching leads 24/7 within pre-set budget limits, an AI Advisor that recommends radius expansion, trade additions and lead prioritization based on regional demand patterns, and a quality guarantee with refund eligibility. Native two-way CRM sync with Sollit and webhook/REST API integration with HubSpot, Make.com, Pipedrive and Zapier route purchased leads directly into installer workflows.

Underlying the marketplace is a documented REST API and webhook layer (POST /v2/webhooks/leads) that enables lead providers to push inventory in an afternoon, plus lead quality scoring that routes each lead to the installer most likely to close. The platform is GDPR-compliant and achieved ISO 27001 certification in January 2026.

Zolar makes money through a hybrid model: per-lead transaction fees (example benchmark of EUR 60 for a heat-pump lead in a Berlin single-family home) layered on monthly subscription terms that are cancel anytime with no long contracts. Leads are sold to a maximum of three installers, capping supply concentration. Following the 2025 acquisition of zolar Installer Services by Sollit, the marketplace is operated by Sollit Germany GmbH (headquartered in Kleve), with regional offices in Amsterdam, Zwolle, Brussels and Madrid. The platform is live in Germany and the Netherlands; Belgium and Spain sites exist but Spain is not yet active. The company is privately held, has no disclosed funding rounds, and reports no public revenue.

Core offering

Zolar operates a digital marketplace that connects renewable energy installers (solar, heat pumps, battery storage) with high-quality, regionally filtered leads sourced from lead providers and platform-generated demand. Installers self-register, define service radius and trade filters on a map, and purchase leads on a pay-per-lead, monthly subscription basis, with automation (Autobuy), AI-driven demand recommendations, and CRM integrations.

Product overview

zolar Marketplace is a single unified marketplace platform for renewable energy leads. The core product is the zolar Marketplace, which connects solar, heat-pump, and battery installers with high-quality regional leads. Built on top of this core platform are add-on modules including Autobuy (automated lead claiming), AI Advisor (demand intelligence and expansion recommendations), and Lead Quality Guarantee (refund policy for unsatisfactory leads). The platform also exposes a Lead Provider API for third-party lead generators and subcontractors to integrate and monetize their lead flow. The platform is operated by Sollit Germany GmbH following Sollit's 2025 acquisition of zolar Installer Services.

Expansion highlights5 records

Direct peers

• Blauarbeit: German lead-generation platform for trades and home-services providers. Closely comparable on geography (DACH), target customer (SMB trades/installers) and per-lead monetization, though broader in trade coverage.
• EnergySage: US solar marketplace where installers compete for homeowner leads, with quality scoring, transparent source information and pay-per-lead economics. Direct peer on category (renewable-energy lead marketplace), though operating in the US rather than DACH.
• MyHammer (Provedo): German trades and home-services marketplace connecting homeowners with contractors (electricians, installers, etc.). Most direct European analogue to Zolar's marketplace model, operating on a lead-generation / pay-per-lead revenue model for SMB trade professionals.

Broad incumbents

• Checkatrade: UK trade marketplace with vetted-tradesman model and subscription/lead economics. Comparable at the marketplace-design level; broader in trade coverage and more established brand but more limited renewable-energy specialization.
• Angi (formerly Angie's List / HomeAdvisor): Largest US home-services lead-generation platform. Comparable business model (pay-per-lead marketplace for SMB pros including installers); broader in scope and deeper in capital/marketing but operates in a different geography.
• Houzz: Global home-improvement marketplace with a 'Find Pros' lead-generation product targeting renovators and installers. Comparable marketplace model but oriented around higher-ticket renovation projects rather than renewable-energy specialization.

Emerging players

• 1Komma5°: German heat-pump and solar installation platform with proprietary installer network. Competes with Zolar's installers for the same end-customer demand pool and is increasingly building its own marketplace/lead flow rather than buying leads.
• Enpal: Germany's leading solar/heat-pump/EV-charger leasing company with its own captive installer network and direct-to-consumer funnel. An emerging disintermediation risk: a large enough captive funnel reduces reliance on marketplaces like Zolar.

Regional players

• Daibau: Austrian/DACH construction and trades marketplace with lead-generation model for contractors. Comparable on geography and SMB-trades target, though broader than renewable energy and primarily DACH-AT rather than DE/NL.
• Otovo: Nordic solar-installer marketplace operating in Norway, Sweden, Germany and others, aggregating homeowner demand and routing to local installers. Comparable marketplace mechanics; different geography (Nordics vs. DACH/NL).
