IT IS IMPOSSIBLE TO IMAGINE THE DUTCH LANDSCAPE WITHOUT THEM: SOLAR PANELS. ON HOUSES, BARNS, GARAGES, OFFICE BUILDINGS, IN MEADOWS. WE GENERATE ENERGY ON EVERY STREET CORNER. THAT’S GREAT, BECAUSE IT MAKES US MUCH LESS DEPENDENT ON THE LESS SUSTAINABLE SOURCES OF ENERGY AVAILABLE. BUT WHAT DOES IT MEAN FOR YOUR BUILDING IF YOU WANT TO INSTALL SOLAR PANELS? WE ALWAYS SAY: CHECK THE CONSTRUCTION OF YOUR ROOF FIRST!
The first types of solar panels are made of glass and weigh almost as much as the roof of a hall. Much lighter panels already exist, but they may not be lifted by wind, due to occurring wind suction. Most panel-bearing systems for flat roofs are fitted with ballast tiles. This means that only stronger but also stiffer roofs can support these solar panels. Older buildings often do not have roofs with sufficient load-bearing capacity. But also, the type of roof, even if it is a new roof, determines whether there is sufficient load-bearing capacity for solar panels. In addition, the type of insulation package also plays a role.
STRUCTURAL CALCULATION
We make structural calculations for roofs, both older and newer roofs. We determine whether it is possible to install solar panels and where they can best be installed. We do this based on our own checklist and a visual inspection, all in accordance with current safety standards. Recurring points of attention are the snow loads to be calculated, which in some cases are higher due to the restriction of free blowing – this applies to panel support systems. In addition, the risk of water accumulation on relatively lightly designed roof structures is a major concern – sufficient emergency overflows are a requirement here.
ADVICE
When a building structure and/or roof structure is insufficiently strong for the installation of solar panels, we make a recommendation. Often in consultation with the client and/or owner of the building. After all, this person has an energy ambition that determines the number of solar panels needed to achieve that ambition.
FOR WHO?
Now you will think: Pelecon advises large clients, mostly for utilities and logistics. But we also advise smaller clients. For example, for a smaller office building or to make a small residential area more sustainable. Feel free to contact us to discuss the possibilities.
