Photovoltaic array support materials
The solar array of a can be mounted on , generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle. If the panels are planned to be mounted before the construction of the roof, the roof can be designed accordingly by installing support brackets for the panels before the materials fo.

How to design a photovoltaic array?
Designing a photovoltaic array requires considerations such as location, solar irradiance, module efficiency, load demand, orientation, tilt angle, shading, and space constraints. It is crucial to optimize these factors for maximum energy production and cost-effectiveness. 2.
What are the components of a photovoltaic system?
A photovoltaic system consists of various components that work together to convert sunlight into electricity. The main components of a PV system include: Solar panels: These are the primary component of a PV system and consist of numerous PV cells. Solar panels are responsible for capturing sunlight and converting it into electricity.
What is a photovoltaic (PV) array?
A photovoltaic (PV) array consists of PV panels which can be connected either in series (S-series array) to increase voltage or parallel (P-parallel array) to increase current or both (S-P array) as shown in Fig. 4.2 b.
Can a solar array support structure withstand a wind load?
Even fixed solar array support structures have sofisticated design, that needs to be analyzed and often improved in order to withstand the wind load. The same applies of course to adjustable designs to an even greater extend. The analysis has to be carried out for many wind directions.
Is mechanical design of a PV array within the scope of this document?
Mechanical design of the PV array is not within the scope of this document. BRE digest 489 ‘Wind loads on roof-based Photovoltaic systems’, and BRE Digest 495 ‘Mechanical Installation of roof-mounted Photovoltaic systems’, give guidance in this area.
What is a photovoltaic mounting system?
Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. [ 1 ] These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). [ 2 ]

What are the requirements for a PV installation?
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.
Are there any UK standards relating to a PV installation?
While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:
What is a roof mounted photovoltaic system guidance?
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.
Do solar installers have to comply with building regulations?
However, tradespeople have to comply with all building regulations while carrying out any job. This includes using materials that have been approved by relevant certification bodies, to ensure your solar installation doesn’t endanger any occupants. Your installer is legally bound to adhere to all building regulations.
How should a PV system be designed & installed?
From the outset, the designer and installer of a PV system must consider the potential hazards carefully, and systematically devise methods to minimise the risks. This will include both mitigating potential hazards present during and after the installation phase.
Do I need a building regulations approval for a PV system?
Building Regulations approval may require the product to have passed the wind uplift, water penetration and spread of flame tests (see section 2.1.1.2). These will usually be applicable only where the PV is integrated into the fabric of the building.
