solar panels..
« on: September 02, 2015, 10:07:06 PM »
I see in the papers today that the gov is in the process of stopping all fit payments for solar panels, that is for those brought into operation after 2014, first they intend to lower the rate of payment down to a mere %, and then in 2019, stop it all together.  With this in mind, do you think the council will now review its purchase of the two solar farms it intends to build and prevent a big loss of money and taxpayers time..

No Tel, they still have international agreement to keep up with and it makes sense anyway.

The government grants were only to encourage sales - pump priming you could call it, there is a good take up now masses of housing sporting them here and over in Abbey Meads.  The prices are coming down accordingly. 

The offer was very good, but as we are in our dotage we didn't want the hassle that the joint ownership might put a burden on our kids when we were not here any more.  We could have afforded it straight out but Mr Muggins felt that we might need that for our extreme old age, and that it's a dodgy time for us to be making big decisions.

I would have had them and bought them outright in heartbeat.

Oi! Listen mush. Old eyes, remember? I’ve been around the block a few times. More than a few. They’ve knocked down the blocks I’ve been around and rebuilt them as bigger blocks. Super blocks. And I’ve been round them as well.  The Doctor (Night Terrors)

I had them put up and our bills have gone down and we get the fit payment every three months so is looking good, and this new proposal doesn't harm anybody who had them up before 2015, so its looking good for the next 20 years, not that Ill see it through..

That's spot on Terry. Depending on when you had your panels put up your FIT will be around 15p per Kwh (and that's for every unit you generate, regardless of if you use it yourself).

The new proposals will hit the domestic market hard. For large installations like the ones the Council is proposing, the payback comes partly from FIT buy almost equally from Export tariff. The latest proposal I saw was to reduce the FIT by around 75%, which could to an extent be mitigated by Community ownership.
As virtually all the electricity generated by the Council schemes is for export they will still be potentially viable, however payback times will change.

Re: solar panels.. replacing roofing tiles

Hi,y roofing battens need replacing so have to take concrete tiles off and then fix new batterns (new insulation?)  so thought might as well get rid heavy tiles and use solar tiles on rafters instead of on top of roofing tiles.


Anyone got any recommendations for solar or reliable roofers that might be able to lay solar tile kit?

Also thinking of taking chimney down to roof level.

Solar roof tiles often come up in conversations about how things "should" be done but I don't know anyone who supplies or fits them in the UK. I believe that they are available in Germany. Better get "Googling". A German company may supply and fit them for you?

Well, were are some!

http://www.jewson.co.uk/media/202979/solar_century_pv.pdf

Little tip that I picked up while fault finding Solar PV installations.

Check what the "Switch on" Voltage is for your planned Inverter. I had one that needed 330Volts to switch on. Each Solar panel gave out between 34Volts and 43Volts and there were 8 in a string. 8 times 34 = 272 so they did not switch on until the sun was high enough to give 41.25 Volts at each panel.

 Remember also that Photo-Voltaic panel output, using current designs, has a voltage drop with higher ambient temperatures. This installation only worked on a very sunny but cold day and the guy only get half what another installation gets in power generated per annum.

I think that the Inverter and Panels were incompatible in that the Inverter was designed for a string of 10 panels

Get some guarantees of power output before buying!!!

Virtually all inverters now have an MPPT front end Outer so that problem shouldn't occur in a modern (new) installation.

Karsten, also take a look at these http://www.solariboost.co.uk/ they work well, especially if you are out at work during the day and not using much lecky. I've had 'free' hot water virtually all summer with extremely little gas used to heat the water.
