360° vertical locking joint technology: the male and female ribs of the rolling seam are closely fitted to meet the requirements of wind resistance and waterproof in most areas; Sliding support: through the sliding of the support and the deformation of the roof cover plate to release temperature stress, wind resistance and waterproof performance is long-term reliable; Pre-filling sealant: to provide better watertight, airtight performance, and anti-rain and snow freeze-thaw performance; Usually the panel field pressing: no lap at the non-luminous plate, reduce the roof leakage potential; Hole-in connection: The pre-punched roof plate is connected with the lapped back plate preplanting bolt hole-in connection with the outer plug at the ridge; Triple nut relaxation technology: ensure that the roof lapping is in long-term service conditions, the fastener performance remains in the initial state, and the node is waterproof.

Recommended lighting panel through the length layout, improve component layout area, improve the roof utilization efficiency (up to more than 80%); According to the different column distance, lighting rate, the roof design provides the best lighting belt and photovoltaic module optimization layout scheme.
