Can't find it? Post it, and we'll source it.
When your usual distributor doesn't have it, list what you need, one part or a whole project. Sunhub searches its inventory and partner network, and puts the rest in front of suppliers as an open request. It's a free service from Sunhub.

Why it exists
Your distributor doesn't have it. Now what?
Installers and EPCs lose days calling around for one inverter, a pallet of a discontinued panel, or the last few parts of a job. Source Center turns that search into one request: you list what you need, and Sunhub does the looking.

Questions
Source Center, answered.
What is Source Center for?
Finding equipment your usual distributor doesn't have. Post one hard-to-find part or a full list, and Sunhub does the searching for you.
Is there a charge for Source Center?
No. Source Center is a free service from Sunhub. There is no charge to post a request, have our procurement team source it, or receive and compare quotes, and no obligation to buy. You pay only for equipment you choose to purchase.
Can I request a single item?
Yes. One inverter, a pallet of a specific panel or a box of flashings: a single line is a complete request.
What happens after I post?
Sunhub's procurement specialists check inventory on Sunhub and hunt down offline stock from manufacturer partners and distributors, then send you a quote with pricing and lead times. Anything we can't place goes on the open request board, where suppliers submit competitive quotes.
What if it isn't listed on Sunhub?
Add it as a custom order. That's exactly what Source Center is for: our team finds equipment that isn't in the public marketplace.
Can I upload my list?
Yes. Upload a spreadsheet, takeoff or PDF, paste a list, or build it line by line.
Do I need exact quantities?
No. Give your best estimate, or use the quantity estimator to work out a full system's equipment from its size. Your engineer confirms the final takeoff.
Can suppliers respond with an alternative?
Yes, if you allow it. Mark each line as exact model only or equivalent accepted.
I'm a supplier. How do I quote?
Browse the open request board and submit a quote against the requested scope, quantity and delivery, including freight and terms.
