The present invention relates to an insolation correction method, an
insolation correction device, a computer program, a model, a model generating
method, and a model providing method.
10 [Background Art]
[0002]
Recently, the introduction of renewable energy has been instigated in order
for global warming countermeasures or the like. Photovoltaic power generation
that is one of the renewable energy has an advantage of not generating greenhouse
15 effect gas, and is expected to be widely used. It is necessary to predict the
insolation in the construction plan or the actual operation of a photovoltaic power
plant.
[0003]
In Patent Document 1, a system is disclosed in which at a point where an
20 insolation is actually measured, an actually measured value of the insolation is
compared with an estimate value of the insolation that is obtained by a predetermined
calculation expression, using weather satellite image data relevant to the point,
parameters of the calculation expression are adjusted such that an error between the
estimate value and the actually measured value is an allowance or less, and the

insolation at an arbitrary point close to the actual measurement point is estimated by
the calculation expression using the adjusted parameters.

[Summary of Invention]
[Problems to be Solved by Invention]
10 [0005]
However, in the system of Patent Document 1, an absorption coefficient of
the insolation according to aerosol particles or moisture vapor is also considered
together with the weather satellite image data, but the influence of the cloud is not
sufficiently considered. In addition, there are a plurality of weather information
15 service providers globally providing weather data including insolation data, but the
insolation data provided by any of the weather information service providers may
have a large deviation from the actually measured value of the insolation.
[0006]
The present invention has been made in consideration of such circumstances,
20 and an object thereof is to provide an insolation correction method, an insolation
correction device, a computer program, a model, a model generating method, and a
model providing method in which insolation data having a small deviation from an
actually measured value can be provided.
