The standard approach when
simulating photovoltaic output is to employ
Typical Meteorological Year (TMY) data sets.
This paper uses statistical analyses to
investigate several TMYs. The objectives are:
(1) to ascertain which TMY generation method
most accurately reproduces solar conditions in
the UK; (2) to discover the minimum time
resolution at which TMYs delver reliable
results; and (3) to determine if there are any
circumstances in which TMYs can replace
long-term time series
