Technical Notes & Briefings
Technical detailing to enable the installation of Clearline fusion at roof pitches below 20°. This detail may also be considered for roofs close to the minimum pitch (below 25°) and subject to additional risk factors such as a highly exposed location or older, uneven (non-planar) roofs.
NHBC 2024 Technical Standards require roof integrated solar systems to comply with durability requirements – how does a housebuilder demonstrate compliance with this new requirement?
How does the use of by-pass diodes in modern solar panels avoid the damaging effects of partial shading due to leaves or localised soiling, and what advantages does half-cut cell technology offer?
New technical guidance for 2024 from NHBC requires that any roof pitch with roof-integrated solar is treated as having an impermeable covering – this document outlines roof ventilation requirements according to BS 5250 to comply with this requirement.
Solar panels for pitched roof integration might be fixed to a range of different roofing sub-structures. Since it is not always possible to safely extrapolate results from testing on one roof-type to another, Clearline fusion has been tested with a wide range of different roof build-ups.
What the introduction of MCS012 means for solar installers. How the new requirements for wind uplift resistance, fire ratings and weathertightness impact roof integrated solar systems.
Solar panels installed in the roofline have lower levels of free ventilation and operate at higher temperatures than systems installed on rails above the roof covering. But how much does this actually affect the energy yield from PV panels?
Building Regulations control the installation of roof integrated solar systems, which must have a fire rating for the external spread of flame. What this means for solar installers.
How to ensure that the solar system you are fitting has a high enough wind load rating for the location you intend to install it. The difference between the wind loads on solar systems installed above the roof and integrated in the roof.
