What are the installation conditions of the collectors so as to increase energy savings?
The energy coverage rate of a solar water heater depends chiefly on: 1) The orientation of the house: the best orientation for solar collectors if directly south. 2) Solar mask: these are the shadows cast by a building, a tree or a wall that mask the sensors from the sun. 3) The number of collectors installed (depending on the insulation rate). However, care must be taken to avoid overheating: if the number of panels is overdesigned, the overall installation will be damaged. 4) The inclination of the panel that depends on the location of the country with respect to the equator (e.g. the ideal value for France is 45°), but performances are hardly affected at all if the inclination is greater than 15°.
