Huge variety of locations and structures will accept PV array
Ground mounting often very cost effective & practical option
Structures such as pergolas, shelters and canopies can be created or adapted to take PV
Tracking devices can boost performance by 20% or more
Siting considerations Orientation and pitch Ideal site is one that faces south with a slope of around 30-40 °. Other orientations and pitches may also be viable with relatively little drop in performance
Other factors Shade - Any shade, such as from trees or neighbouring buildings, can make a large impact on performance To work effectively, the whole PV array needs to be free from shade for the majority of the day Size - a 1kWp PV array will occupy at least 8m² of roof. Positioning an array too close to the edges of a roof may compromise the aesthetics of the installation and has implications on wind loading. Rule of thumb: 1kWp array per year …
