PV system fires potentially exacerbated by gap between solar panels, rooftops

I would like more solar panels now that I installed a heat pump system for my space heating. Waiting for products and solutions to become more plug and play and building part integrated. My dream system would be a semi transparent modular awning system for a south facing nitche in my back yard mated to a battery backup capable of running my heating system at night and perhaps my hot water and or water pump in the daytime with ability to disconnect from the grid in case of emergency. My present system inverter is not high enough capacity to handle enough new panels and the fire potential would be greatly reduced by glass free standing modules.
