I am trying to finalize between installing Tesla and a local vendor that uses LG360 Neon 2 panels. Both are using different layouts, so wondering if Tesla is optimized. My house is east/west facing, and the local vendor plans to install all 20 panels on the east facing roof which gets the most sun. Tesla layout suggests they will install on both east and west facing roof.
A 7.2 kw LG system with generate 7,143 kwh, where as the Tesla 8.16kw system is quoted to generate 7,549 kwh. Looking at PVWatts, for my location, the 7.2kw should generate 8,698 kwh and 8.16kw about 9,858 kwh. Should I believe the PVWatts numbers or the numbers being quoted by the installers? Fortunately, the vendor numbers are lower, so safer to be conservative.
