@BRE_Group#buildresponsibly
FlexiSolar works in line with the following regulations:
Regulations
BS EN 1991-1 Eurocode 1: Actions on Structures

Regulations
BS EN 1991-1 Eurocode 1: Actions on StructuresWind loadingsThis is particularly important for multi-storey carpark installations as the effect of wind loading increases the higher the structure is off the ground. Full wind loading calculations should be completed in line with ‘BS EN 1991-1 Eurocode 1: Actions on structures’, defining the wind loadings specific to the UK, to ensure the solar carport frame, foundations and the structure it is attached to can withstand the potential wind and, where relevant, snow loads. For further considerations of wind loading specifically for variations of roofmounted PV, reference can also be made to BRE Digest 489.
BS EN 1991-1-7: General Actions. Accidental ActionsImpact from vehiclesSolar carports should be designed to withstand vehicles impacting the structure at speeds of up to 20mph as described in ‘BS EN 1991-1-7: General Actions. Accidental Actions’.

Regulations
C632 Guidance on Glazing at HeightOverhead glazing regulationsCarports should only be accessed from underneath the roof structure as the PV glazing is classified as a fragile roof. Consideration should be given to both the potential risk of the PV glazing being broken from above and underneath the carport. ‘C632 Guidance on glazing at height’ provides guidance on assessing and mitigating the risk through good design and product selection.
BS 5489-1:2013 Lighting of Roads and Public Amenity AreasLighting regulationsCar park lighting levels are specified in ‘BS 5489-1:2013 Lighting of roads and public amenity areas’. Adequate lighting promotes a sense of security for car park users and also protects against legal liability for claims resulting from vehicle collisions at low light levels. Good lighting design can save energy and avoid light pollution.

Sutton, Gibson Road Carpark | Sutton Council Solar capacity 133KW
Case Studies
• Installed in early 2018 to the top 2 levels of a multi-storey carpark.
• Bespoke solar carport structure from FlexiSolar was part of the car park refurbishment plans.
• Allows already existing EV charge-points to be more energy efficient.
• Project came with access limitations and height restrictions which had to be overcome for the successful installation.
• Estimated that the 480 module array will generate 116MWh per year.

Barnsley Town Centre Parking | Barnsley Council Solar capacity 24KWp | Parking bays 9
• Part of the Better Barnsley town centre redevelopment scheme, Barnsley Council commissioned a bespoke solar carport solution for its new Market Gate Carpark.
• Commissioned to generate sufficient electricity to make the carpark lighting energy neutral.
• Based on the FlexiSolar V-Frame construction but was manufactured with modifications to the legs.
• Allows for better disabled access.
• Glass on glass PV modules integrated into this design allows some daylight to pass through the roof without any reduction in electrical efficiency.

Harvey Hadden Sports Centre | Size: 40 Parking Bays PV Installation: 65 kWp | Annual Yield: 50 MWh
• 40 car parking spaces support an array of 448 solar panels delivering 50.0 MWh of electricity per year.
• Nottingham City Council are hoping to generate up to £8000 revenue per year from the project.
• FlexiSolar worked with Sitec Infrastructure Services, and EPC EvoEnergy and project managers TSCC.
• FlexiSolar was instrumental in the design phase and project conception bringing their wealth of solar PV and structures knowledge to the team to deliver the UK’s largest and most ambitious solar carpark to date.
