Very large scale solar electric system maintenance inspection

[im4pvru]

We are beginning to see large scale solar systems built - with thousands of individual photovoltaic modules - so many that it is probably not plausible to check each one. There may be "dead" modules; there may be individual modules that are underperforming (dirt, shadows or something more insidious); there may be an opportunity to wash the solar modules and get an instant ROI on the cost of the washing. There may be a need to check stress and strain the structure.

Could an AQL-based inspection be set up?

Any recommended people in the AQL field who chould provide some short term help in figuring out a robust program?

Many thanks,

Can anyone help out here?

Some type of statistically-based sampling can be worked out, but practicality is another matter. For example, the solar arrays being on the tops of mountains in another state might mitigate against a rigorous inspection plan.

Thanks - the issue may be different from what you're thinking. Large solar systems in sunny areas are likely to be on large expanses of flat land and may be valued in the tens and hundreds of millions. There may even be on-site 24-hour security.

That said, it may not be practical to have 100% inspection, hence the inquiry.

We at RecoverIR have developed and perfected a way to conduct an aerial infrared assessment of the performance of very large photovoltaic solar fields which can be used on solar fields well pass millions of panels in size. We can detect dead panels and panels with partial failures. Our accuracy is very high and we are capable of evaluating solar plants prior to commissioning, after commissioning, and creating panel based databases for conditioned based maintenance programs to not only direct repairs, but develop failure and performance trending relative to panels. We are the only company which can achieve this effectiveness which is far more accurate than having men walk around solar plants to manually find problems, such as disconnected or stolen solar panels, and we do not have to ever enter the facility. We have other breakthrough techniques to support identification of problems, quantification of reliability, and more accurate performance trending.

Hello friend bit old thread but I have been searching for similar robust program so can you please help me out? Waiting for reply thanks in advance..
