Hello all,
today is a big day. First part of my PV array is happening with the fitting of the panels themselves. The wiring will take place later, once the installer has received the inverter. I wanted to install all at once but my DECC grant was running out at the end of March and they refused an extension, saying that I need to have at least the panels installed by month end. So that's the task for today. I'll post some pics as work progresses.

Coming on nicely.
Are they cleaned tiles or have they been replaced?

Panels are now installed. first array of 5  second array of 8  last array of 9  In total 22 panels, 175wx22= 3850kW. The inverter will be installed as soon as it arrives but no firm date yet! |

Well done. Looks good and hope you don't have to wait too long for the inverter. I thought you were allowed 4 months to install and the EST were sympathetic to extensions with the shortage of inverters.
How similar are the elevation angles?
If they are more than 10 or 15 deg different, you may have an issue with different arrays developing different outputs.
Does anyone know what difference can be tolerated?

The EST showed no sympathy towards extension despite the acknowledge inverter shortage and the plea from my installer asking why I could not be granted an extension when some of his other customers were.
Bothe roofs share the same 22.5º slope.

looks great. There seems to be a real inverter shortage all over Europe. I hope you get sorted soon.

Hi Sean,
yes the shortage is virtually worlwide. Usual stuff: everybody cut production right down because of the crisis and now that demand is better there's a delay for the components to be made. And as apparently the German market is expected to shrink, manufacturers are reluctant to push production volumes.

I think part of the inverter shortage is due to ever increasing demands from EU directives for these devices. This complexity and ever increasing requirements locks out Chinese production that would solve the supply problem. Whether this is Europe attempting to protect home industry or build a very clever renewal grid, I am not sure.

most installers and supplyers are getting inverters late around 9/2010

Just a thought... with all that power currently going to waste, why not connect an appropriate amount of panels up to your immersion heater to run it off DC power until your GT inverter turns up?

Sounds like a good idea. Unfortunately I haven't got a clue how to do this. Can you enlighten me?  Nicolas |

I assuming everything on the roof is now done, so you should have cables down to an isolator (or perhaps several isolators) before it goes in to the grid-tie inverter. If your system is similar to ours, you may find the power out of the DC isolators will be around 200 volts, this being so, this can be connected up to your immersion heater. At the immersion heater, you'll need to remove the flexible cable from the mains spur outlet, and then connect the flexible cable vis some fused leads to one of the DC isolators. Whilst its not 230 Volts it will work, but take longer, and its free  ). Since you may be without your inverter for several months, ask your sparky about this, as his time may cost more than what you'll save. Before the internet police jump on me, here's a bit of legal stuff - Now you do need to be part P qualified to under take this sort of wiring as non qualified people can no longer carry out domestic wiring! Plus if you need to ask, don't touch it as it can be very dangerous and potentially lethal. |
