Shall not have any objects attached to the PV module, or shadowed live cells. In order to make a better waterproof roofing system performance, flat solar tile must be installed staggered joint. Please according to roof structure, area, orientation to choose the appropriate standard system. Please check the system BOM (bill of material) and tooling list complete or not, before installing. System must be performed by qualified personnel with professional or trained personnel for installation, commissioning. During installation, do not to bring solar array circuit the positive and negative. Solar PV tile strictly prohibit to gravity trample, collision, hard hitting. Brief Instruction of Solar roof tile power generation system. PV tile on‐grid system consists of PV tile, on‐grid inverter, protection of electrical switches and other components. During installation, do not to bring solar array circuit the positive and negative. Solar PV tile can convert solar radiation into direct current, then through on grid inverter converts direct current to alternating current for the use of loading or into the public electricity grid.
