The marketplace for renewable energy jobs
One marketplace to fill your project calendar with high-quality solar, heat-pump and battery leads from your own region — digital, transparent and straight into your system.

The marketplace built together with experienced installers




Old way vs zolar
See the difference between chasing cold lists and running on the zolar Marketplace.
Most lead sources are a black box — no idea how a lead was generated or how often it's already been sold.
You spend hours chasing prospects who never pick up — while your installation crew waits for the next job.
You buy leads blind, often unqualified or out of area, and burn margin on calls that lead nowhere.
You buy leads in bulk on long contracts that don't flex with your business.
Every lead shows its source, type and location up front — and is sold to a maximum of 3 installers, never more.
Live jobs from your own region land in your feed — claim the ones that fit and book them straight in.
We regularly check lead quality, and if you're not satisfied you can request a refund.
Pay per lead on a monthly basis, cancel anytime, and dial your volume up or down — scale up for growth or ease off during holidays and sick leave.
Create your account, set your region and trades, and start picking leads the same day. No onboarding, no IT department required.

Filter live requests for solar, heat pumps and battery storage across the marketplace by region, project size and building type — and claim only the ones that fit your crew.

Turn on Autobuy, define your areas and filters once, and zolar claims every matching lead the moment it arrives — so you never miss a job while you're up on a roof.

Watching your areas around the clock
AI advisor
The AI advisor watches demand in your area and shows you exactly how to win the most leads — which to claim, the best regions to expand into, and which trades you're leaving on the table.
The moment you buy a lead it lands in your system — no copy-paste, no lost details. Get a real-time, two-way native sync with Sollit, and push every other lead into HubSpot, Make.com, Pipedrive, Zapier or any tool you run via instant webhooks and our open REST API.

When we have more capacity we take more leads; when it's quieter we scale back. No other provider was this flexible.
A decade of experience
The zolar Marketplace is built by two teams who have spent a decade making installers more efficient and profitable.
Installing renewables on the ground since 2016, zolar then transformed into a platform that helps installers run efficient, profitable businesses across Germany.
Since 2013Sollit has helped installers work effectively and profitably in the Netherlands since 2013 — bringing deep operational experience to the platform.
Sollit acquired zolar Installer Services in 2025 — uniting German and Dutch expertise behind one marketplace.
For lead providers & subcontractors
Whether you generate renewable-energy leads or you're looking to place overflow as subcontracts, the zolar Marketplace turns them into revenue — transparently and with fast payouts.
Payouts land the following month and you never chase an invoice — we handle the accounting. Set your own return policy for invalid leads.
See exactly what each lead earns and how it converted. No black box, no hidden margins.
Push leads in via a documented REST API or webhook. Most providers are sending their first live lead within an afternoon.
Our scoring routes every lead to the installer most likely to close it — so your conversion stays high and disputes stay low.
Win new customers with the zolar Marketplace — digital, transparent and easy to plan around.
