Understood. Thanx for the info. W/any net metering, use the PVWatts output, orient most panels as possible at optimum annual orientation and then next most favorable orientation for the remaining panels, etc. until the total annual output is what you want to offset in terms of annual load. If ground mounted, set high off the ground and use one orientation that gives max. annual output per installed STC kW. That'll probably be close to south facing tilted at a bit less than local latitude +/- a bit.
A respectful suggestion: Spend ~ $20 and buy a copy of "Solar Power Your Home for Dummies" @ bookstores/Amazon/etc. It'll help get to the preliminary design easier and help avoid gross overdesign from things you may not know about.
