solar hot water

while finding optimal tilt and azimuth angle in parametric analysis, I would like to have annual irradiation value in output in place of hourly irradiation. is there a chance by which i can do that to make my analysis more sensible?

Hello,

The Solar Water Heater model does not report a total annual irradiance value. You can use the "Q Delivered," "Solar Fraction," or "System Energy" output variable instead.

Best regards,
