1. The optimum orientation is ‘due south' (not ‘magnetic south') as this will maximise the sunshine and/or daylight.2. The optimum pitch of the PV Module is 30 degrees. At this angle, the PV Module will 'self clean' as much as possible.

3. A PV Module fitted at less than 10 degrees pitch will need regular manual cleaning.

4. An array of PV Modules can be a very effective source of electricity production, depending on the size and number in the array. This could provide a consistent sour...
