Live from the Houston and Dallas floor. Everything here ships or picks up the day you order it.
From a small off-grid cabin to a commercial rooftop, Solwel has the bill of materials covered. We are an authorized distributor for Sol-Ark, EG4, FranklinWH, Sigenergy, APsystems and more, stocked in Houston and Dallas for fast fulfillment nationwide.
Tiers are reviewed quarterly on trailing 12-month volume — not per order — so a slow month never costs you your rate.
Tier thresholds and discounts shown here are placeholders for the design review — Tony to confirm the real bands before this goes live.
Order online, pick up today, or let us stage the whole job and ship it together.
