Evaluation of proposed photovoltaic energy rating standard: validation against outdoor measurements
conference contribution
posted on 2009-09-07, 16:21 authored by Jyotirmoy Roy, Tom BettsTom Betts, Ralph GottschalgEffective energy production is the ultimate purpose of photovoltaic devices and thus
should be considered in describing device
performance. This paper investigates the
impact and relevance of the proposed IEC
energy rating standard reference days on the
energy prediction of various device
technologies in the UK climate and found
MIMT and MIHT are most relevant. Three
different module technologies have been
tested over a wide range of module
temperature (Tmod) and irradiance (G) level in
outdoor measurement conditions. Performance
of each technology is calculated in terms of
distribution of energy generation with the main
influencing parameters. The paper also
compares the power distributions (with
irradiance and temperature) of crystalline
silicon modules in indoor and outdoor
measurement conditions. Sensitivity analysis
of energy yield estimation and its modelling
accuracy are analysed for three devices with
the different combinations of Gmod and Tmod
and its found that c-Si and a-Si device
technologies underestimated by 7.6% and
6.8% but CIGS module overestimated by
0.05% in the UK climate.
