2 Examples of arrangements for solar preheating
3 Flat plate collector
4 Annual solar energy supplied by the example system
as a function of collector class and effective area
5 Variation of the solar energy supplied by the
example system with a class E collector, with
orientation and tilt of the collector
6 Components of force in a solar collector
7 Variation over the UK of the annual mean daily
global irradiation on a horizontal surface (in
MJ/m2)
8 Mean daily temperature (in degrees C) for the years
1941-1970, reduced to Mean Sea Level, 0.6 deg C/
100m
9 Orientation factor Ch for irradiation
10 Orientation factor Cg for peak irradiance

values of the collector area parameter M and the
collector type parameter K

values of the storage parameter R and the collector
type parameter K
13 Controller operating curves
