PV flat roof design considerations​

In the UK, solar photovoltaic (PV) is the most popular renewable energy and its deployment is rising rapidly across the globe, particularly because climate change and resource scarcity are on the agenda of every government and major corporation in the world. With recent fluctuations in energy markets and carbon reductions initiatives coming to the fore,  the number of large, flat roof installations will continue to rise as local authorities and businesses look to reduce their carbon footprint and gain energy security for the future.

All too often within the construction industry, photovoltaic specifications focus on energy generation and outputs of the solar system. Any solar designer or specifier should give the same focus to ensuring the rooftop array is installed with methods that have as little impact on the building and its waterproofing as possible and that the array works to its maximum potential for its entire lifespan, rather than just becoming a ‘tick box’ exercise to achieve sustainability credits.
