For a long time, engineers contented themselves with setting fixed values for degradation and non-availability – often based on recommendations from independent engineers (IEs) – and then passed these assumptions on to the financial team. However, this should end. Responsibility for all energy indicators over the lifetime of a photovoltaic system belongs in the hands of those they plan [...] For a long time, engineers contented themselves with s…

Virtually all photovoltaic panels in the world are made of… sand. Pure sand contains almost exclusively silicon dioxide (SiO2). During several industrial processes, impurities and oxygen atoms are removed from it. This is how silicon is created, consisting of many crystals connected to each other. Polycrystalline cells have reached 20% and are becoming a thing of the past. Until recently, photovoltaic cells were made from such polycrystalline si…
