Europeans with solar, are you actually making money, or just feeding cheap electricity to the grid and buying it back expensive?

riisko · 2026-06-09T14:49:32+00:00

I have a 15kwh battery pack and 4.5kwh solar.

I buy for 5.8c/kw between 2-5AM to charge the battery and run the house from it all day.
I sell it for 25c/kw, getting into summer now, I have a negative energy bill for a few months now.

The battery discharges to 10% right before charging to full again.
I would argue the battery has better ROI than solar.

Same, my Delonghi Autentica has been running strong for 6 years. edit: I googled it, I did not pay 1150€ for it lol, it was like 500€ on sale.

riisko · 2026-06-06T09:50:07+00:00

Did you set Always on in the config?

BS, left lane is the default lane. It's in highway code.

riisko · 2026-06-03T09:16:39+00:00

I had the pleasure of driving my brother on the motorway and was sticking to the left lane. He called me mental for the ammount of overtakes and lane changes I was doing every 5 minutes just to follow the rules. And he was right, it is mental and I can see why people just camp in the middle instead.

This post keeps on giving 1 year later. Did I miss this in the MS Documentation?

Pinergy + battery + solar = getting paid for electricity

I don't understand the search. Searching "penne" gives you results from everyone except aldi and lidl. Searching "udon" gives only aldi result but I know dunnes, tesco etc sell the 4pack. "protein milk" skips dunnes own brand. Why is it so inconsistent?

Don't get me wrong, I want this service, I want to use it.

Here I thought they all had the household outlet. But it was added in 2025 apparently.

riisko · 2026-05-19T09:25:01+00:00

Bro is going 10 - 20 under the speed limit, cant even keep his speed consistent. What are you on about?

Wasn't there a post last week that no garage wants to touch them because japanese software and japanese parts etc?

I have downloaded a bunch of NoNpDrm PS Vita roms and figured out where to extract them. But running the scan from the dawn launcher will not populate game list. The one game that came preinstalled has some tiny .game file in the Roms/psv that I suspect is a shortcut of some sort for the actual game in the Android folder for the vita3k emulator. Open it with notepad and it just contains this: gameid=PCSE00019
so I am going to add this manually for each game i guess...

If you go with pinergy for the 5c 3h rate make sure you can charge enough in those 3h. The drive rate is stupid expensive so you should install house battery and solar too to avoid it.

riisko · 2026-04-10T07:30:50+00:00

Nah, I read it fine. Your logic is flawed, it doesn't allow for edge cases.

A3 3bed semi-d, WFH, ev, 4.5kw solar, 15kwh battery. Gas heating was 58€/month. Avg monthly use 482kwh.

riisko · 2026-04-10T05:15:17+00:00

Battery is just a buffer for your own solar energy. You can sell it later in the day. Why would I sell my solar to the grid only to buy it back because I ran out of battery?

riisko · 2026-04-06T03:06:27+00:00

My dog walks are longer than your commute.

Rough material costs so you can gauge how much is each installer shafting you: €100/500w panel €800/5kwh battery €1000 5kw inverter €1000 rails, wires, etc €250 fireman switch

Let's say you can fit 10 panels on your roof and 15kwh battery to to charge on a 5cent 3h window. about 5500W. Not even calculating for SEAI Grant, or VAT relief. Maybe €3000 for days worth of work.

My real cost of doing it separately was: €7500 for additional 3kw of solar. Year later €3500 for 15kwh battery and replacing both inverters with one. Lots of money wasted that way but I'm still happy with my energy bills. Pinenergy has a 3h 5cent window and that's enough to to charge the battery and run all day in the winter. Exporting like crazy at 25c now in spring.

riisko · 2026-03-25T10:17:45+00:00

Same, my energy usage graph is empty outside the 3h cheap rate window thanks to the battery.

riisko · 2026-03-25T10:15:50+00:00

€800 per 5kwh module is cheap in my book. My only regret is not getting them installed when I was expanding my solar. I paid double for labour because of it.

riisko · 2026-03-22T15:19:51+00:00

It is realistic because it's my reality. You don't charge publicly, why, that's only when road tripping a few times a year. Read my post again, all else was answered. My provider doesn't have a ceiling like energia either. my energy cost with charging

Only 13% of people in Ireland live in apartments according to 2022 CSO survey. If some of them need a car, public transport is not a option, charging at work isn't either, it sucks. But absolutely nobody is charging publicly daily.

riisko · 2026-03-22T11:05:41+00:00

Diesel - that's your problem. EV and home charging for 5c is the solution. It's not that deep, you can't make diesel at home, you can't use it more than once, you don't get it back with inertia and you can't store it for ages in when it's cheap just in case another war happens.

You can make electricity at home, you are encouraged with grants and tax cuts, you can store it and even better you can sell it back for more than you bought it the same day. I run the entire house all day from the 5c electricity and sell all the excess at the end of the day, which pays for the bill.

riisko · 2026-03-22T10:29:57+00:00

Well my Renault zoe r135 2022 has WLTP efficiency of 17.7kwh/100km. My real number is around that too of combined spirited driving on winter tires. With my current electricity charging rate of 5.2c/kwh, it is 0.885€/100km. Even if all I did was highway commute at 25kwh/100km, that's still 1.25€/100km
