Installers must only fit solar panels if they''re sure your roof can hold their weight, and carry on doing so for up to 40 years. Fortunately, most roofs in the UK are built to hold much more than a solar panel system, which
"16.12.5.2Where applicable, snow drift loads created by photovoltaic panels or modules shall be included." Therefore, both the IRC and IBC state that the loads imposed by the PV panels on the roof must be considered and the new or

The size of the path along the ridge depends on how much of the roof is covered in PV panels. For roofs where PV panels cover up to 33% of the total area in plan view (essentially, as seen from above), the panels must be at least 18 in.
Solar photovoltaic panels or modules that are designed to be the roof, span to structural supports and have accessible/occupied space underneath shall have the panels or modules and all supporting structures designed to support a roof
An increasing number of people are investing in solar energy. More and more homes are having solar panels, or solar tiles, installed on their roofs. Of course, with such installations, the topic of planning permission and building regulations often comes to the surface.
If you wish to install a solar panel on your roof building regulations will normally apply. The ability of the existing roof to carry the load (weight) of the panel will need to be checked and proven. Some strengthening work may be needed. Building regulations also apply to other aspects of the work such as electrical installation.
Your solar panel system must comply with building regulations in terms of structural integrity, electrical safety and fire safety. These regulations may vary depending on the size and type of the installation. It's advisable to work with accredited installers who are familiar with these requirements.
The guidance refers only to the mechanical installation of roof mounted integrated and stand-off photovoltaic systems; it provides best practice guidance on installation requirements and does not constitute fixing instructions.
Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.
The guidelines also say that provision must be made for ventilation behind the solar PV modules to provide cooling. With the introduction of MCS012 in March 2012 we would now expect all MCS certified installers of solar PV systems to install solar PV systems on pitched roofs using only MCS012 certified roof fixings.
