Minimum height of rooftop photovoltaic panels

Spacing between the PV panels should be sufficient to allow maintenance and safety, and in accordance with manufacturer guidance. 6. The height of the panel at its lowest point should be 200mm above the substrate. 7. PV Panels should be at least 1.5m from the edge of the roof and 750mm from the edge of rooflights or atrium features.

PV Panels should be at least 1.5m from the edge of the roof and 750mm from the edge of rooflights or atrium features. 8. There must be a firebreak of 1m width every 40m. PV Panels should not encroach on the firebreak. 9. The installation of the panels and electrical cabling should be installed in accordance with MCS guidelines. 10.

The potential for rooftop solar PV is primarily a function of the orientation of the building/roof. In cold climates, buildings are often orientated to maximize incoming solar radiation. In hotter climates, buildings and associated landscaping are frequently situated to avoid incoming solar radiation.

The GRO best practice guidelines for biosolar roofs clarifies details on roof design, wind uplift calculations, minimum height of panels; construction of the solar base; distance between the roof edge and the panels; firebreaks and necessity of maintenance visit every six months.

Solar bases (that holds the panels) are designed to be integrated into a green roof system and are compliant with BS EN 1991 1-4:2005 and BS EN 1999 1-1:2007 Eurocode 9 “Design of Aluminium Structures” and BS EN 1993 Eurocode 3 “Design of Steel Structures”. 5.

10. Biosolar roofs (green-roof portion) should be maintained twice a year to ensure: Build-up of organic matter does not become a fire risk. Vegetation is not in danger of shading the PV panels. Check that there is a minimum gap of 200mm between lower edge of PV panel and substrate. Old biomass is removed each autumn. Firebreaks are kept clear.
