DIMENSIONING
The dimensioning of the solar heating system starts initially from the identifi cation of its use: only the
production of domestic hot water or the production of domestic hot water and integration of heating.
An inspection of the building is of fundamental importance in order to identify the availability of an
appropriate slope, with suitable surfaces and inclination.
Some general indications for the correct dimensioning of the solar heat system will be described. The
fundamental rule to be respected in order to guarantee good functioning is the suitable costs/benefi ts
ration and not over/dimensioning. There must always be equilibrium between the energy produced by
the collectors and the consumption of the user.
INCLINATION OF THE COLLECTORS
The solar energy that can be caught by the collectors during the entire year varies on the basis of the
inclination on which they are installed. The diagram shown below represents the variation of monthly
energy aff ecting every m
2 of collector on variation of the angle of inclination.
If the aim of the solar heating system is just the production of domestic hot water small inclinations will be
favoured, while in the case of integration to heating inclinations exceeding 45° will be opted for.
The table supplies the general indications for the choice of the most appropriate inclination on the basis
of the type of intake.
Inclination Type of intake of the solar system
30° maximum summer production
45° maximum yearly production
60° maximum winter production
90° minimum summer production
