The purpose of this work is to show the effect of external parameters: albedo and
wind speed) on a solar collector inclined plane. The method used consists in cutting
the collector into fictitious slices (05 meshes) of length Δx in the direction of the flow
of the heat transfer fluid and writing the balance sheets of the exchanges which
intervene at the levels of the 06 nodes: from the outside of the glass, the inside of the
glass, the absorber, in the peddler fluid as well as the inside and the outside of the
insulation. It is convenient for this to use the analogies that exist between the
transfer of heat and electricity, the results obtained are the temperatures at the
nodes.
