The effect of an array's tilt angle on solar PV energy output may be up to 20% compared to that of flat installations. A comparison of data in two US cities has been completed to exhibit the importance of a solar PV array's tilt angle. As a rule of thumb, placing panels at a tilt equal to the latitude of the installation and facing towards the equator will maximize the amount of incident irradiance on. . The sun will be slightly to your south throughout the year if your location is north of 30 degrees latitude in the Northern Hemisphere (approximately the border of Mexico and the USA. Since the location of the sun. . The vertical tilt, or angle, at which the solar panels are installed in a photovoltaic (PV) system will have an impact on the amount of electricity they can generate. Determining the voltage of. .
