Unsure of bonding flexible solar panels on asphalt roof
Ok long story short. I have 8 sun power (windy nation) 100w panels flexible w fiberglass or plastic 1/8 thick backing. they have no frames. im connecting off grid but on a roof asphalt shingles. using morningstar mppt 60 and their gfpd unit, a disconnect/ combiner midnite mpnv6 w some big agms in parallel 12v probably. i havent got inverter yet prob 2000 w continuous at 12v or 24 nor figured my max battery config yet i figure 12v safer. maxing voltage out w panels prob to charger at 12v should i do 24?, mppt says 800 watt max at 12v in so prob do that however i may do 2 strings of 400 at 24v input to charger for better sun insurance case 1 panel fails i got 4 others unaffected instead. im unsure yet. my big question is do i need to bond anything on panels since there is no frame? everything else will be earth bonded to grounding rod. do i need to make metal frame, should i then bond frame to system? what should i do because i need to use these panels and im scared of the current w no earth bond in case of strike or should my panels come loose in a storm or get struck.i feel i may have some extra ground protection w gfpd 150v unit i have to use. some good info would be appreciated. this system will power a 20k saltwater reef off grid but in house without ac tied. separate for me is best and i have intentions of using panels on big boat someday.
