Prepare specification, quantity, and US destination before requesting factory quotes.

SolarSource Sourcing, an independent sourcing partner

The desk exists so a US buyer can ask factories for solar PV module quotations without pretending this website is the factory. We collect the brief, match the request to manufacturers the buyer is willing to consider, and keep each reply tied to a model number.

What the desk will and will not sign

SolarSource Sourcing is not a manufacturer or an authorized distributor. It is not an installer, an engineer of record, or a test laboratory. Those sentences are the boundary around every page on this site. Factory history, audited capacity, and customer awards are not copied from other companies onto this name.

The DOE photovoltaic design overview, accessed on 2026-10-26, provides background on system components. It does not approve a supplier or set a price. Buyers still name rated power, module efficiency with a test basis, cell technology, dimensions, connector, and maximum system voltage for their own job.

  1. Read the buyer application and reject vague watt-only notes.
  2. Ask candidate factories for model datasheets and drawings.
  3. Place freight, documents, and exclusions in separate columns.
  4. Return gaps to the buyer instead of filling them with assumptions.

Checks that remain open after a quote arrives

  • Whether the listing file, if one was requested, names the same model as the commercial invoice draft.
  • Whether open-circuit voltage and string current fit the inverter the buyer will purchase elsewhere.
  • Whether pallet count and connector kits are inside the quoted quantity.
  • Whether a quality-system document refers to the plant that would build the lot.
  • Whether structural, fire, and utility approvals are owned by the project team rather than this desk.

A family brochure fails the opening check. MPPT range and DC-to-AC ratio fail the second check if nobody has stated them. Those limits are written so a quotation is not mistaken for a finished design.

Hypothetical document-review example: a buyer asks for 720 modules at 550 W and requests confirmation of a 1500 V maximum system voltage. A family brochure that does not identify the quoted model leaves the voltage and dimensions unresolved. Request the exact-model datasheet and drawing, record the file revision, and return that evidence to the buyer's engineering reviewer. These are illustrative inputs, not a completed purchase or a verified product rating.

How a reply is judged comparable

Specification. Identical watt band and efficiency note, or the difference is highlighted.

Quantity. Same module count or an explicit conversion from pallets.

Delivered scope. Incoterm, packaging, and accessory list visible.

Supplier documents. Model-specific file names, not a generic catalog link.

Bring the brief to the desk

Use the form to send specification, quantity, destination, and timing. Add currency and a per-module or whole-order basis if you have a target budget. Mark supplier preference as high-end, mid-range, budget, or not yet decided. The preference is yours; it is not a score we verified. A lower equipment price is useful when the scope matches; an offer with included freight or clearer warranty terms may better fit a whole-order budget. Keep required safety evidence fixed while comparing those commercial choices.
