Samenvatting:
One of ECN's laboratory buildings was renovated using PV-systems. Thepower performance of all PV-systems was monitored on a daily basis (supervision
monitoring) and of two selected systems the power performance was monitored
in more detail (analytical monitoring). The report presents the results
of the first year of monitoring. The supervision monitoring revealed
the failure of a serious number of inverters. With the analysis monitoring
data a number of aspects, important for building integrated PV, were
quantified. These aspects are:
-
Thermal behaviour of the modules
- Loss of irradiation due to shading
- Additional energy loss due to partial shading (mismatch)
- Effect of dirt
Furthermore the irradiation data were used to validate the shading module
of the design tool PVsyst. It was shown that PVsyst is a reliable tool
for shading calculations.
