Perhaps regarded as the more ‘traditional’ way to install Solar PV, On-Roof systems will be less expensive than In-Roof, and this has obvious appeal. We use a specialist and independent structural engineering company to assess wind and snow loading for all installations and a comprehensive 13-page report is produced to say whether the existing roof can take the new array without any structural alterations being necessary. To date, all have been OK, and this includes 100 year-old barn roofs, so your roof will more than likely already be suitable.
There are several options to provide protection against fauna nesting under the PV Modules. The image here shows a particular product called SolaSkirt, which although expensive, many customers love and feel that it provides a sleeker finish. The less expensive ‘bird mesh’ is also popular, as from the ground it is virtually invisible, giving a more natural look.
