Unpredictable summer weather can sometimes bring high winds and hailstorms which can cause concern and result in damaged roofs and buildings crops. This can be why some potential investors have sceptical views on the endurance capabilities of a roof top PV solar system.
Testing has shown that Bisol premium quality photovoltaic modules sustain various rigorous weather conditions. They can endure wind gusts of up to 200 km/h and are resistant to hail stones 25 mm in diameter, which fall perpendicularly at 83 kilometres per hour onto the module.
Bisol PV modules are able to sustain this kind of weather due to the solar cells being airtight and encapsulated with two layers of special EVA foil and they have the additional protection of a 3, 2 millimetres thick and highly transparent layer of glass on the front and the back sheet on the reverse side. The glass is thicker and lighter than the competitions, and consequently the roof is less loaded during the storm.
Torrential rain falls quickly off the roof during a storm due to BISOLs clever solution of drainage holes in the aluminium frame. Not only are they excellent for draining surplus water, they are also very effective during cold weather as they prevent frost damage too.
In summary, Bisol PV modules are lighter than the competitions and are very robust. Each panel is approved for a short term heavy mechanical loads of 900 kilograms and can normally sustain a weight up to 400 kilograms. The modules can be used in differing climates as they can endure temperature cycling from 40 °C to +85 °C at 85 % humidity.
They also exhibit very high energy yield in both low and high irradiation areas. Furthermore, BISOL PV modules are very resistant to time degradation. TÜV artificial PV module aging simulation test confirmed the minimum degradation of the modules. It achieved only 0,5 percent of the permitted five percent. That is why Bisol can offer 10-year product warranty and 25-year warranty of 80 percent power output for their clients.
