Our Unglazed transpired solar collectors (uTSCs) work on the same principle as the huge commercial installations used by DHL, Amazon, and FedEx — and supplied by companies like Tata Steel, SolarWall®, and Matrix Air. Same hole configuration, same hole diameter. The only difference? They use coated steel. We use high-grade aluminium.
