Tested and commisioned . Its so good :)

Popped back in to run some final checks, take some readings and generally see how the system has got on over the weekend. Its clocked up 75kWh over the 2 days during the weekend of mostly cloudy with a little bit of sun here and there. Very encouraging!

I spent some time on site this morning, as I had some network cabling to finish, and a whole bunch more pictures to take now the sun is out for today. .. By the time I had left at lunchtime, another 20kWh had been generated. Its such an incredible system, the customer is going to notice a major difference in their power bills, plus of course the building occupiers have taken a huge step toward reducing their carbon footprint.



Two pictures taken with a super wide angle lens to get everything in on one shot. Perspective is a little distorted though.

18kWp array completed!

Taking advantage of the good weather, we have completed the 18kWp array this afternoon. All connections double checked and output readings verified, so working well!

Tomorrow we'll be commisioning the inverters onto the buildings 3 phase power circuit and finalising tests and certification.

The whole array went in very smoothly onto the Kalzip roof. Although there were 4 times as many brackets to install than other roof mount systems, because no structural or drilling work was involved, together with usual waterproofing, this system has a sleek low profile design with no mess to clean up.

Modules are starting to go on!

Today have got all the external and internal cables runs in place throughout the building. All has been kept concealed internally, plus the modules are now being installed and tested.
The project going according to schedule with the whole installation, and our customer will be enjoying the benefits of Solar PV generated power by the end of Friday.

close up..

Close up of the bracket mounting system for a Kalzip roof . The roof must not be punctured or drilled in any way, or the waterproof integrity would be affected, plus of course any extended warranty would be lost.

These brackets make a solar PV system possible on any Kalzip archetectural system.

Roof hardware being installed

We have made good time installing the roof hardware between the four of us. The Kalzip steel roof profile needed special fixings from Germany, as the fabric of the roof skin must not be pierced.
Some images of the installation progress today (day1)

circuit diagram

Just finished the circuit diagram of the 18kWp system. Just to give a hint of what the size is going to be, I've included a screen shot.

The Big Big system ..

We are on the run up week to starting a huge 18,000 Wp solar PV array installation in Devon.
Pictures and information to be posted next week when the construction starts. Its going to be fun, and we are hoping for good weather... Please!

More soon. C
