I know ALL of you won't like reading it, but hope SOME of you will.

Congratulations and really well done Steve.

Times for a nice cuppa and a piece of carrot cake

Now you can buy a new gooseneck

[keyser soze]

impressive. how long that take you steve?

[Alex Wingrove]

Too long,

[Dave Willis]

So...... how long do you think it will take for the dust to settle again and knock 10% back off the output? About a month I reckon.

If Alex 'flippant' Wingrove is reading ( ) it took a day and half! In reality, 10 days.

Top job Steve, but you missed a bit

Yep, it's right at the back, but who's gonna walk all the back to check? (Believe me, they will!)

Good job on the clean and contract Steve.

It would do my head in. That has got to be some of the most boring work a wfp cleaner can do. 10 days of panel after panel!

That's fine. We are contracted to do it every 6 months.

Get some blistering beats on my iPod, let my OCD kick in and I'm off!!!

Also how can you possibly estimate 10% loss? No days are the same certainly not ten days later so how can it be measured? Take a reading bang on mid day on a cloudless sky and hope for the same ten days later or what?

well done steve

If you have studied irradiance, you can do the math. Sorry, it is possible to work it out.

[Dave Willis]

How?

I'm interested.

Big job like that and I would think the customer is going to want to see results, so how is he going to do it, how will he find out if your ten days of scrubbing at £200+ per day is profitable for him?

Well done Steve, good luck to you.

[Alex Wingrove]

A 10% loss per year on that site equates to over £20,000.

You don't need to get into complicated maths, to realize its worth while to get them cleaned every 26 weeks.

Well done Steve, good luck to you.

Cheers lal!
