There are two distinct roof mounting systems. Most homes use on-roof mounting, with solar panels sitting above the roof tiles on simple rails and brackets. The other option is in-roof mounting, where panels replace tiles to form an integrated solar roof covering. Both options are similar in price. However, on-roof systems allow for greater airflow around panels, improving efficiency on hot days.
In our opinion, on-roof mounting is best for existing homes, while in-roof mounting can be a great option if you’re building a new home. Flat roofs require a customised on-roof solution.
