Frequently Asked Questions

What counts as a "solar distributor"?

Companies that stock and resell solar modules, inverters, or BOS components to installers, EPC contractors, or end-customers. Distributors may also offer warranty coordination and after-sales service.

How do I choose between manufacturers and distributors?

Distributors offer local stock with faster delivery (days vs weeks), local warranty support, and lower MOQ (often no container requirement). Manufacturers offer lower prices for large orders (1+ container) but longer lead times.

Are distributors listed here authorized resellers?

We list companies that self-identify as distributors. For authorization status, contact the specific distributor or the manufacturer directly — PVFinder does not verify distribution agreements.
