Local Tilt Optimization of Photovoltaic Solar Panels for Maximum Radiation Absorption

Table 1

Photovoltaic panel tilt angle to maximize the absorption of solar radiation at different periods of the year. The gain in solar irradiation compared to the standard angle is also shown.

Period (day range)	Tilt (°)	Solar irradiation (MJ/m^2)	Gain (%)
I (1–365)	23.22°	4783.14	0.02%
	22.00°	4782.32
II (80–264)	46.12°	2422.80	7.57%
	22.00°	2252.16
III (127–217)	53.92°	1177.56	14.19%
	22.00°	1031.04
