Solar Module Mounting Structures STC uses top-of-pole (TPM) and side-of-pole (SPM) mounting structures. Smaller modules (16W-30W) use an aluminum bracket (mount) called a minimount (MM-AL). Larger modules (40W-135W) use either a TPM-PCS, SPM-PCS, or a SPM-AL mount. Mounting structures come in powder coated steel (PCS) and Aluminum (AL). Table shows different types:
