  In this paper, we apply the PVGIS method for estimating the performance of
the first grid-connected PV micro-power plant in Morocco. PVGIS approach
provides analysis and assessment of in-site solar energy resources and predicts
with good accuracy the potential of PV systems in term of electricity
production. We find that annual total power generation of the micro-power is
slightly higher than that initially expected at the installation stage and
actually measured. The yearly predicted and measured power production values
agree to about 2 %. However, individual monthly production can have larger
discrepancy.
