SolarRoof power production
I hope someone having gone before me has good info to share. I don't know too much at this point but am happy to share what I can, from a beginners standpoint.
I expected the Tesla website to provide a USA latitude-based chart or spreadsheet on the Tesla SolarRoof shingles so I could determine expected power production per sq-ft of my roof area assuming an optimize roof angle.
*** Does anyone know the power output of the Tesla solar shingles per sq-ft of roof area?
I'll take any measure you can offer, even if its not for the same latitude I need (35.2° for Charlotte, NC) as I think I can interpolate an adjustment based on gov't data on solar energy by region.
By the way, a "simplified formula" I found (https://solarpaneltilt.com/ ) regarding best roof angle was:
- IF your latitude is between 25° and 50°... "use the latitude (35.2° Charlotte), times 0.76, plus 3.1 degrees." So for Charlotte: (35.2*0.76)+3.1= 29.85° angle or about a 7:12 pitch roof.
- Please inform me if you think that is a wrong formula or roof pitch. They did provide an adjustment if you wanted to favor winter or summer energy gains... but that formula was for a year round best setting.
In case its helpful to others who my wish to favor winter or summer gains here is what they offered (based on the same latitudes between 25° and 50°):
• Adjust to Summer Angle March 30th ... The best tilt angle for summer is the latitude, times 0.93, minus 21 degrees.
• Adjust to Winter Angle September 10th ... The best tilt angle for winter is the latitude, times 0.875, plus 19.2 degrees.
