Solar Panels Installation - 13 Uni-Solar PVL 124W 68W 31W

Today is the Big Day !

When I woke up, I discovered a very clear blue sky (what a relief !)

I had to take my day off to be there when it happens, but still I could not sleep anymore 

I checked right away and noticed that the forecast had not changed :-) and that it should be a nice day (all day)

My contractor called me to tell me he would come with one or two employees from another project nearby to help him out here and that he should show up right after lunch break so that the roof would be dry

And now they are here, the boss and one employee, on the roof installing the panels :-)

My last recommandations given showing pictures of the roof (from the sky) & Uni-Solar PVL technical documentation, ...

... my wife and I helped them passing the panels to put all of them on the roof

The ladder and opening to access to the roof

They installed some safety ropes between the chimney stacks

and started cleaning and scrubbing the the zinc so that the tar would stick better

It is getting hot on top of this roof in direct sun :-)

More pictures taken by my contractor:

All this was installed in only two hours and the employee told me it was the first time he installed this kind of panels and that it was easy

The PVL 68W and PVL 124W have been placed on either side of the U shaped building roof, avoiding attic air conduits, East and  West, in two strings of 3 68W and 3 124W; The additional small 31W has been added to the East chain

Here is a particular problem I was afraid of: the zinc sheets, overlapping each other, create a bump; I ask my contractor to be extra carefull at these points and not to try to put too much pressure on them because it would damage the solar panels ... He followed my advice and did better: he added a some silicone sealant between the zinc and the panel, blocking water and sticking this part too, which is a good idea :-)

Closer look at the nice result
I know, we have a lot of shade from the chimney stack, because winter is coming ..., but these panels are working do not really need direct sun to work well, they are fine with a white/grey sky
Also, if the shade is really bad, the cells affected are automatically shunted (each cell has a diode for that prupose), allowing better current flow only in sunny cells 

Awesome ! I am very happy with the job they accomplished :-)

Now I will have to be patient because their "Super" inverter is not ready yet, butI think it is worth the wait (I talked about it with the boss for an hour after the employee was gone)
