I had a letter through form my supplier ( ebico Sourthern electric) and as of tomorrow i will be getting paid 9.2 p per kw/h for every thing i produce and another 5p per kw/h for every thing i export.

So i theory what my panels produce and what i use is saving me about 24 p per kw/h ( 9.2p + 14.5p ( cost of using from grid)
what i export is making me 14.2 p per kw/h

my guess is my system will produce about 500 kw/h per year

I will export about 1/4 of this so 125 kw/h

use 375 kw/h x 23.7p = £90
export 125 kw/h + 18.12
total £108.12 saved ( earned )
cost of system £3500

That's a 3% return on the money !!

Now how do i make the system bigger !!

Very interesting peter - my 488Wp system is nearly a year old and heading for 350 kWh (not roof mounted so some shadowing). Its all DIY and cost about £1800.

So that could be £63 saved and £12.70 earned.... total £75.70 or 4.2% return.

Yikes  That beats just about any bank cash account.  Can anyone sign up for ebico?

Mike at Navitron pointed out that Scottish and Southern are now paying 28p/kWh for solar PV power.

Thanks Ivan - that is amazing news I think.

PV now pays back better than a building society cash account, saves CO2 and is a perfect hedge against future rising electricity prices.

WAKE UP FORUM! - We should all DIY install grid tied PV panels.

That value is for only what is exported,

so that would be in my case 125 kw/h exported  x 24p = £30
plus 375 kw/h x 14.5p 0f saved electricity = £54.37
total £84.73.

Ebico use southern

When i spoke to Southern they put me on the 'lower' tariff as i would earn more as i had a small system. ( which they are right)

If i was able to export more power then the figures may be different as to which is the best tariff

WAKE UP FORUM! - We should all DIY install grid tied PV panels.

I  suggest we should ask Navitron for an offer  and get an order in for a big amount  of PV   ,  all off us

I need another 1.6 KW  anyhow   and have no problem to pay upfront   ( for the next month or two   ,  )

If we get  a good order  together , perhaps a nice price ..... last day of my Virgin moderator  time  

just an idea

Hey Billi

Do you have a grid connection? You know that ESB networks must accept grid connections from micro-renewables now? Info on their website.

Hi Ivan

Any idea how Mike at Navitron found this out?

I'm already on their "Solar EnergyPlus" for PV export, which has been 20p/kWh for some time (only for export - nothing extra for total generation and they take any ROCs). The contract I signed was due top end today (31-Mar-2009) and they said they'd write with the new deal - presumably the 28p/kWh that Mike has heard about - but I haven't heard from them. They (and OFGEM) will presumably also be expecting meter readings - new ROC year from tomorrow.

I can't see anything on their website (admittedly didn't look too much). Found an old document still referring to 18p/kWh (already out of date months ago). WHY DON'T THEY MAKE A BIG DEAL OF THIS??

I believe that double ROCs are to be awarded for solar PV from 1-Apr-2009, so assuming ROCs hold up at (very approx) 4p/kWh, then SSE's new rate isn't entirely due to their generosity, as they'll be getting more benefit from the ROCs they claim on the PV-owner's behalf.

As 'petertc' says in this thread, SSE have also always had another tariff (I think advertised as for technologies other than solar PV, but possible an option for PV as well) which may be more beneficial if you use most of what you generate and don't export much.

So who says that generating power doesnt pay now that oil prices have contracted?

Maybe its time for the big companies to try harder and not shy away from investing, but of course i get the feeling there is little or no financial security to making an investment of this type as the plug can be pulled at any time?

Amy,

Global warming, pollution, population growth and energy shortages will always put upward pressure on fossil fuel electricity prices. PV just keeps on working for 30/40 years so I think its guaranteed to be a good investment.

There is still a big gap between what we get and the German feed-in tariffs, so again there will be political support for better feed-in tariffs especially as the Conservatives are keen to promote home generation.

One day every home will have solar thermal and PV. Buy PV now before the recession ends and oil prices goes up.

Breezy   i know , but we love that live without monthly Bills     Even it gets better here in Ireland ( in relation to grid connections) , i think we stay off the main line  for the time being

Not that i am afraid of the future more then i was 20 years ago , (pretty easy now ), but i like to invest my earned cash now (that i didnot have 20 years ago) into my Interdependency

I would like to support an Idea of a State run (renewable) structure  more , but not at the moment (cause i cannot see that to happen)

So if I install a 3kW system that should generate about 2700kWh/yr. We use about 1400kWh/yr. So that means about 1400*14p+1300*24p (or could it be 28p?), which is about 500 quid/yr. Install cost is about 8 grand DIY, which is a bit over 6% return. That's more than good enough for me but I've been told I have to do the extension, and some more insulation first, which is not as much fun. And I'm not at all confident that panels will be as cheap this time next year as they are now (given exchange rate changes).

I presume Mike was told by customers....but I haven't asked him.

Billi, Yes, we can do bulk prices for solar PV, especially for payment up-front (delay time 2-3months)
