I choose to mount on the ground rather than the roof. If you have the room you can get optimal placement and tilt angle. Grid tie inverters are the way to go. One large one is much more cost effective than the microinverters when calculated dollars per watt.
You can get inverters for about 15 cents per watt. Mounting (that I designed out of unistrut) is about 15 cents per watt. Panels can be had for 50 cents per watt. 10 kW is a pretty good size for most homes. If you oversize it, Rocky Mountain Power will erase all your carryover credit each spring thus selling your net production to your neighbors at retail rate while not giving you any credit for it. So the target is the $8.48 monthly bill (the minimum in Utah when on RMP) and no extra power in your credit account each March. Screw batts. Batts will double the cost of the system. Nice generator with an automatic transfer switch and a propane tank ( if you are a prepper) or natural gas if you are not worried about it.

Seems like several solar panel kit options that use microinverters tied to a main system which ties to the main breaker. But not sure how to integrate battery system into that. Seems like the current solar guys all want to just install the solar system and send extra to the grid or offset, not backup battery. And on top of that, what if I want a standard Generac 11kw generator integrated into the mix? -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
