****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.*****

May and June did not include any vehicle charging as I was attempting to use up my Supercharging miles that were expiring at the end of June.
Due to COVID, my kids were home doing online school and the AC was kept at 76F most of the day.
2020 is shaping up to be one of the hottest years on record (number through Nov 1, 2020):
