Built for installers who buy in volume and ship same day.
Over four years we’ve built a wholesale supply chain optimized for installers — deep inventory on the brands that actually move, transparent volume pricing, and dispatch that beats every distributor in Central Europe.
You order, we ship, your end-customer stays yours. No competing channel, no surprises on lead time, no fight for stock when a subsidy window opens.

Your dedicated account contact.
Every EU Solar Wholesale account is owned by one person who knows your region, your product mix, and your pipeline. Not a ticket queue — a phone number.
He flags stock before it sells out, shares lead times before you’ve quoted the customer, and loops in pre-sales engineering when a project needs it.
Ladislav Proc
Wholesale Director
“We switched three of our supply lines to EU Solar Wholesale last year and haven’t looked back. Fewer stockouts, better margins, and when one of our Goodwe inverters failed on a Friday afternoon, we had a replacement on the van Monday morning.”
“What sets them apart isn’t just the pricing — it’s that our account manager actually knows our business. He flags products we should stock before a subsidy window opens and warns us when something is about to go out of stock. It feels like having a partner inside our supply chain, not a vendor.”

What buyers actually say.
J.W.
Owner, PV installer · Poland
“Margins on our PV jobs are up roughly 8 points since moving to EU Solar Wholesale. Stock is reliably there, and pricing doesn’t move on us mid-quarter.”
S.B.
Procurement Lead, HVAC company · Germany
“We run heat pumps and PV side by side. Having one supplier with one account manager cut our purchasing admin in half.”
M.E.
Managing Partner, solar installer · Italy
“Their account manager at EU Solar Wholesale calls me before subsidy windows open. That alone has paid for our switch three times over.”
