For my esteemed solar energy colleagues, this will calculate annual energy production at 16 different compass headings for a given pitch angle. You will get interactive charts and raw data in a tables.
Address (Do not enter units, apartments, or any extraneous data other than the street address):
City:
State:
Zip:
Module Watts: Enter watts as a number only. You might want to enter 1,000 watts with a quantity of one to model a 1kW system.
Module Quantity: The system rating modeled will be watts above times the quantity you enter here.
System Losses: PVWATTS Default is 14% (enter decimal percentage only without percent sign):
Weather Data: You probably want to leave this as TMY3 unless you are outside the U.S., but if you find it does not work, try a different value.
This tool will output 16 data points showing the monthly and annual kWh production and solar radiation figure from PVWATTS using selected weather data. Currently it only supports the fixed roof mount option.
It will return data as a web page with a radar chart and data table.
Click once - be patient - need to grind out some data!
Use of this tool obligates you to buy me a beer the next time you see me. :)
