Daily pv production

Nahh, nothing like promised. I'll get 30+ kWh, but we were supposedly getting mid 40's kWh (on my 6.5Kwp)

Still at, for the moment, €0.24/kwh that's €7 or so to put in the piggy bank - but yeah, disappointing as I was hoping to see record breaking numbers. Met Eireann you lied to us :-)

May 2024: 465 KWh generated

May 2023: 610 KWh generated

Not great. Hoping for a far better June, July and August than last year!

Do you ever get a bill? or are you always in credit?

What size system in total?

Fair play for the net zero costs! You must have the house almost airtight

This strategy is all about the battery. Even without the ability to dump battery to the grid, and a large PV array, getting above 90% at the cheap rate is doable. Using the standard load profile, and an annual usage of 4200 kWh

No battery is 10.7% cheap rate. 10.9kWh with scheduled charging gets to 79.7%, and 21.8 gets to 96.7% cheap electricity

Not zero, but if you are prepared to gamble on the longevity of big differentials in time of use prices, this obviously works.

Add the other bits, and you are going to be able to shift strategy based on the prevailing market. @unkel is dreaming of flexible tariffs.

Wish I had the cash to follow suit, or the guts to go diy on the battery.

Cracking day to start June off on the right track

@unkel I do follow those DIY battery threads here. Definitely easier now than it was 2 years ago. But it gets a bit more complicated with an existing install, that I'm very happy with.

I reckon a DIY battery with A2A HP would put a big dent in my kerosene spend, but that could not be grid tied. Unless I swapped out...

@unkel exactly. Anything extra I add in summer would go straight to FIT, and in winter simply reduce my bill. Repayment is related directly to FIT.

The is space there to nearly double what I have, and the inverter can take it. But until I need to increase my electricity consumption, I cannot justify it. Maybe when an EV replaces the diesel that owes me nothing and keeps plodding along

You don't get extra panels for self use. Or for diverting to your hot water, or for charging your EVs. You get them purely for the feed in tariff!

To give you an example. A 400W panel at trade prices costs €40 + VAT. In Ireland, facing south, it makes €100 per year in FIT. Obviously there are the costs of installing it. But you get the idea about pay back time, it is insanely good in Ireland. Get those extra panels ASAP 😀

Great start to June.

Trade price from one of the biggest Irish wholesalers

It's incredible how much they've dropped in price.

As Tony Seba predicted a few years ago (and of course he would turn out to be right again), solar panels are now cheaper for use as structural building material than plywood. Think using it for fences, to build sheds, etc.

Nice one. Any pics?

If I had land and I had to put up a boundary wall, I would most likely use solar panels as fencing panels too.
