PV Feed In Tariff

@bullit_dodger - "in theory you could charge up at 8c and dump into the grid at 14c. Make yourself a few quid a month."

with 20kWh usable, you would make 365 * 20 * 0.14 * 80% efficiency and it would cost you 365 * 20 * 0.08, so about €230 net profit per year, before tax. Producing just to export is more lucrative. If you have a 6kwp south facing system in a good area of Ireland, you'd make about 6000 * .14 * 95% efficiency = €800 per year

I intend to make the maximum tax free sum from exporting as soon as I am forced to have a smart meter. And more if I can amortise PV assets and deduct this cost from my revenue 😎

I got my final SSE bill a couple of days ago, including the €50 contract break fee. Glad I switched. I will enjoy the guts of 10MWh of 7.9c night rate over the next year while hopefully keeping the high day rate limited to 2-3MWh and deducting the deemed export pay back from that

Very true. Previously I was answering more a specific question about why wouldn't you dump your battery onto the grid from energy that you filled from the sun the day before. My thinking was the same as you......why fill the battery to dump it the next day, you'd be better off to just export it directly. If you have say 60% left at 9am, I wouldn't dump that. I'd let the sun fill it up and then export the surplus.

Doesn't make sense to incur the losses today for filling the battery tomorrow, when you could leave it alone and export more tomorrow. You with me?

I signed up on the 30th.

They adjusted the discount down from 31% to 25% a few days later, and then down to 15% another few days after that.

Even with the reduction in the discount they're still probably the best around.

So how's this work? Backwards spinning meter?

Speed typing? 😁

You should have gotten an email from Energia with the rates and discount details

Yea, thick thumbs, sorry!

I got a registration welcome email but nothing in it confirming the rates or even what plan i signed up to!

I signed up on the 31st and thats when i received the email, so before they upped their rates

I think it's 14 days by law

anyone clarify what happens when you switch while waiting on FIT. I am with Electric Ireland and they are not to pay FIT until before year end. But I want to switch beginning of next month due to the rises.

I have a smart meter fitted but still am on the old MCC01 connection. I dont want any of these peak tariff rates as these bands will just keep on widening

waiting on a reply from electric Ireland.

I've asked specific questions but I bet the reply will be general

See journal article today. Gov has perfet opportunity to penalise all providers for breaking the rules... for not giving FIT at the August deadline. Such a simple small matter and sure a small payment....

Pay a credit based on NC6 form at install.... on monthly basis, averaged over the year. claw back any overage when smart meter brought in and everyone's happy.

Instead every provider has a different rate and a different rule set and different terms.... and no one has any fit money yet.

Remember every time you cycle your battery you are reducing the life span of the battery. I've seen estimates that it costs about 6c/kWh in terms of long term degradation of battery systems so charging at night rate and feeding in during the day you need to account maybe 6c/kWh for costs battery wear out. If night-rate+6c is less than FIT then it's probably still profitable, but not as lucrative when you consider the battery life.

Technically you are correct, every cycle degrades a battery. But your figures are miles off. A LiFePO4 battery has 2000 cycles per the spec sheet. So yes based on that your figures are roughly right. But what most people don't realise is that after this so called "life" the battery still has about 75% capacity and will be usable for several more decades. If you take that into account, we are talking a cost of maybe a few cent per cycled kWh.

For me, I've a GivEnergy battery and when you buy one of these, you actually get more than what it specifies. E.g. under the hood my 8.2Kwhr battery is actually a 9.6Kwhr one, or something. They do this, so that they can guarantee that after 10 years, I'll still have the same capacity as the day I bought it. In reality of course, like all Lithium batteries, it will have degraded somewhat, but effectively they've planned for it.

I find the psychology of batteries interesting. You buy a battery, spend money on it, but then you don't want to use it to generate the savings that you bought the battery explicitly for as you are afraid of degradin it? It's actually in direct opposition to the whole point. You bought a battery to cycle it - that's it's only job. After the initial "sunk cost", if you use it 100 times a year, or a 1000, you've still spent the same money. It makes sense to cycle it as much as you can (assuming your generating savings with each cycle of course)

That's how it pays for itself.
