Shading: small shadows, big effect
Shading: small shadows, big effect Shading is one of the most common causes of reduced yield in photovoltaic systems – and yet it is often underestimated. What appears to be a minor problem can actually have a major impact on the performance of entire module strings. With the help of drone thermography, such critical shading-related […]
Up to 30% power loss per affected module – Potential-induced degradation (PID)
Up to 30% power loss per affected module – Potential-induced degradation (PID) PID – potential-induced degradation – is an insidious fault pattern in PV systems that leads to considerable yield losses. It occurs without visible damage, but can cause a drop in output of up to 30 % per affected module. Particularly insidious: PID often […]
Craft and digitalisation
The ACTUAL state of the trade Craft businesses are still at the relatively early stages of digitalisation. The first important steps such as digital accounting, planning software and messenger communication are already widespread. At the same time, the IT infrastructure has become more complex – partly due to increasing customer requirements, funding programmes and a […]
Overheating & fire damage – the invisible danger for PV systems
🔥 Suddenly the solar system caught fire… 🔥 The cause? A small, invisible defect – an overheated plug connector – had developed into a dangerous weak point over a period of months. Not visible to the naked eye. But when it was too late, the overheating caused a fire that destroyed the entire system. But […]
Full sun, half the yield – where is the energy lost?
Full sun, half the yield – where is the energy lost? Just imagine: A sunny day, the display of your PV system shows a stable output – everything seems perfect. ☀ But when the statement arrives at the end of the month, they are in for a surprise: The yields are significantly lower than expected. […]
🔥 Hot danger on the roof 🔥
🔥 Hot danger on the roof 🔥 It sounds paradoxical: heat can become a weak point precisely where solar energy is collected. We are talking about so-called hotspots – areas within a PV module in which individual cells become very hot. What begins inconspicuously can massively impair the performance of entire systems. Hotspots are among […]
Thermal fault pattern – module idling: causes and detection
Thermal fault pattern – module idling: causes and detection You can think of an idle module as a team member who is present but does not perform any tasks – it looks ready for use but does not contribute to the overall performance. This state is barely recognisable visually, but consequently leads to yield losses […]
