During the day the sun is practically always visible for an observer looking towards the south.
To capture maximum energy the solar collectors should ideally be facing due SOUTH.
The sun is “high in the sky” during the summer period, and “low” in
winter.
The angle of the solar collectors in relation to the ground will depend on the
period of production.
In France the ideal average angle is:
- 45° for annual production
- 30° for summer production
- 60° for winter production
In practice, we will choose the roof with the best angle and orientation.
Failing this the panels will be fitted to a frame.
Question
In France, at what angle should solar collectors be set to ensure DHW production for a family:
30°, 45° or 60°?
In France, the production of DHW for a family is required throughout the year.
The best angle is therefore 45°.
Question
In France, at what angle should solar cell panels be set to ensure DHW production for a municipal summer camp site:
30°, 45° or 60°?
In France, to ensure maximum heat recovery in the summer the panels should be angled at 30°, since the sun is high on the horizon.
Question
In France, at what angle should solar collector panels be set to heat up a swimming pool which is only heated in winter?
30°, 45° or 60°?
In France, to ensure the re-heating of a swimming pool which is only heated in winter the best heat recovery will be achieved with the panels inclined at 60°, because the sun is low on the horizon.
