Abstract
The study of high concentrator photovoltaic (HCPV) technology under real
conditions is essential to understand its real behavior. The influence of direct
normal irradiance (DNI), air temperature (Tair), and air mass (AM) on the
maximum power of two HCPV modules was studied for more than three years.
Results found are presented in this paper. As expected, the main influence on the
maximum power is DNI. Also, Tair has been found to have small influence on the
maximum power. Regarding AM, two different behaviors have been found. The
maximum power could be considered independent of AM for AM 2, while it
decreases with an approximate linear behavior for AM > 2. Also, the maximum
power of a HCPV module could be estimated with a linear mathematical fitting
based on DNI, Tair, and AM
