****If you find this information useful and are looking to order Tesla Solar or a Tesla Auto, please use my referral code to place your order to get a $100 solar award (currently) when your system is activated or 1000 Supercharger miles (currently) for a car purchase. Tesla Solar recently announced on June 19, 2020 a 20% price reduction (The Lowest Price for Home Solar) and they also now use the 340 watt panels (up from the 315 watt panels that I have). This will cover the $99 down, making it zero out of pocket initial cost when financed.*****
The following is the actual performance of my Tesla Solar system (and I plan on keeping this updated as time allows so check back occasionally for the latest information).
Location: Phoenix, AZ
System Size: 12.285 (39 – 315 watt panels)

House Size: 2 story/2965 square feet with swimming pool/AC set at 79F during the day and 76F at night
Electrical Consumers: 2 Tesla Model 3s, 2 AC units, Mini-split AC, Evap Cooler (garage), Electric Dryer, Variable Speed Pool Pump
