6 FAQs about [Ventilation-permeable photovoltaic panels]

What are the different types of PV installation?

There are two main types of PV installation: integrated into the roof surface, often referred to as Building-Integrated Photovoltaic (BIPV) systems or mounted above the existing roof covering, also referred to as stand-off systems.

Can a PV system be integrated into a flat roof?

In some cases, PV systems can be integrated directly into flat roofs (Figure 25), although this is not common because the efficiency of PV modules is reduced because the optimum angle relative to the sun is not achieved.

How much does a flat plate solar thermal panel weigh?

an appropriate system of mechanical lifting should be provided. Flat plate solar thermal panels can weigh up to 80 kg each when installing an integrated PV or solar thermal system, the underlay should always be checked for tears or other signs of damage and replaced as necessary.

Are solar thermal systems heavier than PV systems?

Reproduced with permission from European Solar Thermal Industry Federation (ESTIF). Solar thermal systems are generally heavier per m2 than PV systems due to the weight of the heat conducting fluid and pipe work. Therefore, the structural stability of the roof will need to be assessed.

Can a PV system be electrically installed?

Guidance exists for electrical installation of PV systems[15, 16, 17] but there is little equivalent guidance for mechanical installation.

Do PV systems need special care?

PV systems and need special care. ‘in all circumstances the building’s weather tightness must be maintained. Holes drilled through roofing felt and/or roof tiles/slates sealed with mastic or silicone sealant are not considered durable.
