Orientation and tilt
Planning permission - solar electricity
"Your roof should ideally face due south at a pitched angle of around 30° from the horizontal to give the best overall annual performance. Installations at any pitch and facing anywhere to the south of due east and due west are feasible, although output and income will be reduced. Installation is not recommended on roofs facing north.
This table shows the percentage of the ideal annual output you will get for a system with a different orientation and tilt:"
