Development of software for PV plant parameters optimization. I. The tilt and azimuth angles of solar panels

Keywords: PV plants, PV modules, solar radiation, irradiance, insolation, anisotropic radiation models, tilt angle optimization, azimuth orientation, PV energy yield


To obtain maximum power generation by PV plant the
following setting parameters of PV modules are essential:
tilt angles, azimuth orientation, distances between module
rows. In this paper, the algorithm and the program in
MATLAB for optimizing the tilt angle and azimuth of
receiving surfaces are. The mathematical model is based
on maximization of the theoretical expression for the total
sum of solar radiation on the atilted surface. The experimental
hourly data for irradiance on a horizontal surface provided
by meteorological stations are used as parameters. Transposition
to data on a tilted surface is carried out with aids
of anisotropic radiation models of Hay-Davies, Reindle
and Klucher. The program allows calculating the optimal
angles for any calendar operational period and any region
for which the long-term radiation data are available. For a
stand-alone PV plant, the influence of the electric load and
the constrained battery capacity on the optimal tilt is considered.
In the article the results of calculations for several
regions and typical calendar operational periods are given.
