Great month just 1Kw less than August total this month 234.5KwH last August 235.3 2.5Kw system in Louth West facing

Best day today 31 12.3Kw worst day 2 March 1.1Kw

Hit 2100kWh since install 23 April 21

6.9 kWp south facing.

March Stats

6.2kWp (2.8 south/3.4 west), 20kWh battery, Zappi & Eddi – Donegal

Generation – 523.1kWh, a whopping 65% increase from 2021

Export – 2kWh (down from 20kWh in 2021

Import – 279.4kWh, decrease of 28% from 2021. Also managed a 95% night rate usage.

Best day – 28th 26.4kWh

Worst day - 2nd, 2.1kWh

Days with zero purchase - 7 (and another 5 with less than 1kWh.

Overall my consumption was up by 14% from about 700kWh to 800kWh so to reduce purchase and export so much is impressive, and all down to the whopping battery.

6.1kw dual array. 12 panels south ground mounted and 7 west roof mounted. 5kw battery and eddi.

491.5kwh this month.

2.8KW array, South Facing, Meath, No Battery installed, 10KW battery here :-) Need a firmware update on inverter to use :-( Battery would have knocked €50+ off the bill.

I think I need to plug the car in more during the day, or maybe get a bigger battery

Like everybody March has been a great month.

8.16kWp Midlands facing 200° 35° angle, 5kWh battery, Zappi, Eddi and several heaters on smart sockets.

Generated 880kWh

Used 456kWh

Battery took 168kWh for a self use rate of 71%

256kWh went back to the grid

115kWh imported, mostly on night rate

11kWh to Eddi

182kWh to Zappi

Yup - stellar month for March here in South Dublin. 5.3Kwp (split 1.5Kwp due East/3.8Kwp due West)

4.1Kwhr to the grid for the month. Must "have a look"....:-)

Main thing is that it's a €100/month. Physiologically that's a great milestone to achieve.

Thats some serious export to the grid, and I can only assume that number will grow?

Do you have an EV?

254kWh would equate to around 1,700km in my car!!! I put about 85kWh in the car in March, and am looking out at pretty much free motoring now until September!

First full calendar of Solar - a great month of weather to start with.

755.7kWh generated.

For the second half of the month have been putting some 10kwh a day into a heater, after immersion is done. Daily Energy Used rose then.

Compared to the same period last year, when had oil boiler on morning and evening to heat water / rads, this year the boiler has not been turned on at all since March 15th.

Afraid I've moved on to the website.

2.5 kwp system south facing ,Galway City.

Total for March was 314.6kwh.

Best day was the 18th with 16.2kwh.

Worst day was the 2nd with 1.6kwh.

March total was best since July last year and the second best month since install.

March on the 7.8kw of panels in Louth produced 874Kw.

Best day produced 44.1kw
