POSITIONING SOLAR PANELS FOR MAXIMUM ENERGY

There are a few important factors to consider when deciding upon the positioning of solar panels – albeit some systems can operate well on daylight, getting more direct sun onto your solar panels will capture more energy.

1 – Shading

The most likely time to have shading from surrounding buildings or trees is when the sun is lowest in the sky – sunrise and sunset. Even though they may only partially shade a PV array it may have some impact – however -if it mostly only applies to the periods mentioned above then it will have only a small effect as little power generation will be taking place then anyway.

If however it appears that shading may occur during other periods then seek advice regarding re-positioning

2 – Orientation and Angles of elevation for solar panels

This is fairly straightforward – in terms that the more southerly a solar PV array can face, the more energy it is likely to produce.

MySolarPower has discussed however in other sections on this site how it is possible via "A frame" installations etc to manage an array if roofing directions do not match requirements.

Simply 30 degrees to 45 degrees from the horizontal is the best angle within the UK.

3 – PV Array size (Numbers of panels)

It may seem fairly obvious but the greater the number of solar panels within the array, the greater the level of solar energy capture.

An Average solar panel size is approx. 1600 x 800mm so the greater the number you can manage – the better.

At this juncture we would advise that you discuss with your selected accredited solar supplier and solar installer so that assessment can be made regarding weight loading roof capacity etc.
