Solar Panel Guide Discussion

Thanks for your reply Dave, as far as the shading goes, we are directly south facing, so I think in the summer, we don't have shading until about 4pm. I have attached a pic taken yesterday at 4pm of the roof. The £16k seems a bit over priced for the second system but I guess if it pays overt ime it may be the better choice.

Hi

With that roof, if going for a larger system the 'optitrac global-peak ' (http://www.sma.de/en/products/knowledge-base/optitrac-global-peak.html) system on a SB4000TL would probably be a better solution than the Fronius ....

On the smaller system, if the inverter is a SB3000TL then I believe that it has this available too .... check it out and ensure that it's turned on by the installers.

Looking at the roof & without measuring .... are you sure that a 4kWp/Sanyo system would fit ? .... it certainly looks a little tight ...

The roof is 6.7m wide, and about 6.6m long, so the diagram that I was sent squeezing them in just about, with 7 along the top, 2 more to the left of the bay and 7 to the right of the bay

Is there anyone with a south facing roof and a bay window that already has a system?

What do people think about the prices quoted? £16k for a 4kWp Sanyo HIT system??

We paid less than that (albeit not under the current rushed climate) with a Sunnyboy3300 inverter. Quote should be in the £12-13K region.
Good luck with it all!

I believe the current issue is with getting the parts - our installer (working now, panels gone up today) is having to buy panels from the Netherlands to get installs completed that are are already committed pre 11th December. Parts that were simply 'in stock' are no longer. The delivery of roof rails has arrived without fitting brackets - gone out of stock, no date available. He is tearing his hair out (well, he would be if he had any).

I don't think the £5.7k extra for a 1kWp extra system is economical. Stick with the Tesco one. Agree with Zeupater too if you have the Optitrak system with the SMA.

The panels don't generate at night, their output during the day is patchy and unreliable, and they don't reduce our generating capacity by a single power station.

However even accepting your argument that Solar PV is necessary(which I don't) then how do you justify scores of thousands of tiny systems dotted all over the UK, right up to Northern Scotland.

Windmills need the wind, wave power needs waves, coal fired power stations need miners to dig the coal out of the ground and then transport it inconvenient distances to get it to the power station, oil and gas the same, often imported from unstable and hostile countries....yes they all have their pitfalls, but they are all important parts of the mix. Oh yes and the "green" card is an important one as well, unless of course you are a climate change denier!
Oh and one last point which I have made before....every renewable generation resource installed reduces the consumption of your precious coal, gas and oil so it will be available for longer to make up for the times when renewables aren't delivering.

Should we start the thread now:

"My installer/electricity company missed the 11th December deadline - what are my legal rights?"

Can I refuse to pay ?

My installer says they cant get the rails or the Sunnyboy:mad:

They cant give me a starting date yet though "hope" to start in two weeks.

I looked throught the details of the R.E.A.L. document, and it seems we cant clobber the installer if the holdup problem is outwith their control ( weather, suppliers etc ?)
