Here is a Glass Patio, building on a stand alone Metal Structure.
Spare the roof for visually aesthestic reason, also for safety concerns.
They can be multiple different designs. Canopy or Awning can also be other options!
1. Fire Chief’s Alert
Fire Chief had asked Californian to reconsider to build Solar Array away from the conventional Gable roof?
Because during a fire, the fire fighters many not find the Solar Disconnect to disable the PV array.
If there is a high voltage, normally 400V solar array? The Fire Fighters have the right to decline to go up to the roof.
Because they need to break a big hole to inject fire retardant foam to save the houses that are on fire.
2. Cleaning of the PV array
PV panels gather dusts and need to be cleaned once a while. Going to the roof will be a task unsafe for home owners
An stand alone Metal structure could be easily cleaned by a water hose or a long brush.
