I think you should concentrate on cleaning them & your own business. You know yourself, 90% would be bollox anyway!
My interests extend beyond physically cleaning panels, but in moving the industry forward as a whole. It may be 90% if you were doing it, but the people involved are professional course collators, administrators and assessors.
I'll be a bit more diplomatic because you seem like an alright bloke Steve.
But a qualification in cleaning solar panels, really?
I'd concentrate on what your doing, you seem to be doing rather well.
These type of courses are a nice little gravy train especially if they get funding.
But in all honesty all these collators, admin etc love it when a new course comes along, it keeps them in a job.
Take a look at the impact courses everyone on here was raving about them (owt for nowt syndrome.
)
As soon as they aren't free nobodies bothered.
That tells me they weren't necessary.
