CABLE TRAY SUPPORT
Photovoltaic support foundation
The solar array of a can be mounted on , generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle. If the panels are planned to be mounted before the construction of the roof, the roof can be designed accordingly by installing support brackets for the panels before the materials f.

Requirements for rooftop photovoltaic installation without support
no higher than four metres;at least 5m from boundaries;size of array is limited to 9m 2 or 3m wide and 3m deep;should not be installed within boundary of a listed building;in the case of land in a conservation area or in a World Heritage Site it should not be visible from the highway;only one standalone solar installation is permitted.

What size cable tube should I choose for photovoltaic panels
Why 10-American-Wire-Gauge (AWG) is selected as the standard for external connection of solar arrays due to the following:Oversized for safety & voltage dropLow resistance for solar current of 30 Amps per single panelThe voltage drop over distance is lowCable is flexible [pdf][FAQS about What size cable tube should I choose for photovoltaic panels]
