The last couple of days have been exceptional. 3.96kwp system near Skegness Lincs. :j
15/11 14.25 kwh
16/11 13.30 kwh
Notably there's been no sign here of any of the fog I've seen mentioned on the national weather forecasts.

That sounds excellent. What is your roof angle and orientation?

I'm guessing pretty much due south, with a steep roof pitch to get figures like that at this time of year?

mysterons

Orientation is actually SSW and pitch is around 35 degrees as far as I can make out.
Not sure if I can add pictures on here



Hmm, seemed to work ok

18 Sharp 220w panels to a sb3300

Would I be right in thinking that sb3300 is Sunny Boy - which sounds Far Eastern but is actually a leading German manufacturer?

That's the one.

Other than SSE and BG, who you have to be a customer of to benfit from free systems, are there any other companies who install free systems in Scotland?

Hi All


Link to November benchmark for european pv panel spot market pricing .... http://www.solarserver.com/service/pvx-spot-market-price-index-solar-pv-modules.html

European manufactured panels are down another 1.1% on the month, total ytd is now -11.8% ...... additionally the sterling v euro exchange rate has moved 3.5% in favour of the pound in the last month ....

spot prices are wholesale , generally by the MWp or lots
of 60feet containers , will not lead to savings
on domestic systems with 6 to 20 modules
will on a solarpark for 10,000
also around 80% of modules sold especially very low price
thin film are not on the mcs list , therefore can,t be used in the uk

Hi I have been informed yesterday of the Government's incentive plans to begin in June 2011 to reimburse (if thats the right word) all buyers of - in my case - air source heat pumps which I want to install. The deal is that the Gov will repay the cost of the pumps over an 18 year period. Just want to double check with you all that this is accurate as it came from an installation company. It is a great incentive in my opinion IF IT IS TRUE!!!

As for Heat pumps?

Excellent, You need to ask what the co-efficient of performance is for each type and choose the highest, commonly these can reach as high as 5.5 for a new commercial mitsubishi type (cant remember the model) But this would not be suitable for a domestic dwelling. a coefficient of performance or COP as its commonly reffered to is measured as energy in to energy out (ignore the 1st & 2nd laws of thermodynamics and if your confused then PM me!) So if you use 2Kwh to run the compressor on a ground/air source with a COP of 4 you would get 8Kwh out (less volumetric, isentropic efficiencys and system losses) So yes its like having a boiler thats 400% efficient! There brilliant, drawbacks are that because they run at about a 40^C feed and 20^C return Temperatures there not suitable for traditional radiator systems, however they are great for a new conservatory or new build home where you can install underfloor heating as a 40^C & 20^C return is ideal!!!

(I am trying to read through the posts on this thread but there are so many I may have missed something on this subject)
.

This is what I understood too - that air source heat pumps were only efficient when used in conjunction with underfloor heating - which I havent got. I have radiators only. Ecovisions (installer) told me it would work fine with radiators. So I don't know what to believe now. I don't what to shell out £7k if its not going to work - Government incentive or not.

Hi

It doesn't really matter what the analysis is based on, if there has been a reduction in spot prices of 11.8%, there should be a reduction of 11.8% in panel prices throughout the supply chain and therefore onto your roof. Failure to pass on savings simply swells profit margins for installers, there is no other reasonable explanation.

I tend to disagree with the analysis of spot prices being based on container loads. The spot prices are based on general supply of single/multiple pallet loads to the industry, large volume supply will be scheduled supply not spot and will be (is) subject to considerable discounts to the prices shown in the survey ...... UK based wholesale price lists for single pallet loads are generally in line with the referenced analysis and therefore confirm this to be the case.

Thin film is analysed separately, the 11.8% reduction ytd quoted is described as being for crystalline modules.

It is up to the business model for each MCS installer to decide whether to buy individual panels, pallet loads (typically 20/30 units) or container loads, and also whether to buy through wholesale or, if the organisation is large enough, directly from the manufacturer.
