How a PV grid connected cabinet is made, how resistant the environment is created for them in terms of its technology will affect the durability of a full set. As most photovoltaic systems have an operational lifespan of well over 20 years, a good quality cabinet will easily last this long. The cabinets are actually built to take any punishment thrown at them, thanks to offering IP65-rated houses that protect against all forms of dust and water ingress.
The choice of materials, is important in longevity. Cabinets with corrosion-resistant finishes made from galvanized steel or aluminum are resistant to extreme temperatures in the range of −40°C to 55°C. For example, a solar farm designated for production exposure in the Middle East used such cabinets with high durability against desert conditions for a long time without any way of losing operation efficiency.
It heavily relies on adherence with standardized norms such as the IEC 61439, which guarantees electrical safety and endurance. Vibration resistance testing is another area that manufacturers such as ABB and Schneider Electric say need to be rigorous, especially in locations susceptible to seismic activity. For example, an earthquake resistant PV grid connected cabinet installed in a solar project in Japan survived the 7.0 magnitude quake.
Reliability is further enhanced through the use of cooling systems like forced air or natural convection, which maintain operating temperatures to avoid overheating. A state-of-the-art thermal management cabinet ran unobtrusively through a California heatwave, while outside temperatures climbed above 45°C. Research indicates that boards with upgraded cooling systems could see an up to 30% increase in dust-free months for components within.
Elon Musk looks to renewable energy with the expectation that infrastructures are permanent: "Sustainability starts with systems designed to last." This vision also highlights durability, which is why a PV gird cabinet will need to be chosen based on this parameter.
Lifespan is also influenced by routine maintenance intervals and modular designs. When cabinets are modular, it just means that parts of them can be taken apart and replaced easily enough to reduce downtime while extending functionality. A solar plant in Germany recently upgraded existing cabinets, with components nearing the end of their 15-year lifespan, for 40% less than new system installations.
Longevity also gives you a bang for your buck, and reliability in tough conditions which is another important factor.
