Mechanical load (hail, wind suction, wind pressure, snow parameters which are responsible for the ageing of PV modules). For the standard IEC 61215 certification, 2400 Pa uniform load applies. However: When installing solar panels in areas with heavy snow, an increased load capacity of 5400Pa is advisable.
Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
Nowadays many solar manufacturers produce according to this requirement. Solar system installers who do installation in areas with heavy snow should definitely use products with an increased load capacity: 5400 Pa.
This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This recommended practice does not include PV hybrid systems nor grid-connected systems. This recommended practice covers lead-acid batteries only; nickel-cadmium and other battery types are not included.
Ballasted, unattached PV systems on low-slope roofs have to meet seven conditions to comply with seismic load requirements in Section 13.6.12. For low-profile systems, the height of the center of mass of any panel above the roof surface must be less than half the least spacing in plan of the panel supports, but in no case greater than 3 feet.
The majority of UK PV installed capacity is grid connected and approximately 72% of the installed capacity in 2008 was supported by grant funding through the Low Carbon Buildings Programme and other grant schemes. There are many different types of roof-mounted PV systems in use in the UK.
