Practical Example

A common 5 MW plant consists of 20 blocks containing 18 strings with 45 modules each. This makes all in all about 32'000 connectors on modules plus approx. 3'000 for field assembly/installation. In total, there are approx. 35'000 connectors - 35'000 small details to influence LCOE as well as ROI positively. In the case of downtime, defect connectors disable current flow and inevitably stop the energy feed-in. However, the failure of only one single connector can also entail the outage of an entire string.



Practical Example

Please note that all of the sources of risk and problems mentioned in "Sources of risk" are likely to occur not only once but several times in a row. Multiplying factors (plant design, number of affected connectors, hourly service rate etc.) and their impact on the efficiency of the plant have to be considered as well. Defective components and improper installation may lead to many lost kWh, high service and maintenance costs and even total breakdown/destruction.
