I thought perhaps some of you might be interested in this given the sunshine we’ve been having this week. This graph is an overview of what happened yesterday.
– The green line up top is my battery charge status read by the % on the right vertical axis.
– The blue line down bottom is electrical power consumption of the house.
– Yellow is electrical power generation from solar consumed directly in real time.
– Green is electrical power used to recharge the battery from solar.
– Grey is solar power exported to the grid.
For the full day yesterday we consumed basically nothing from the national grid (0.07kWh) and though yesterday was a very bright day this has been the case since March 20th this year whereby we’ve been effectively fully powered by our solar panels.

Is there any kind of net metering in Ireland where you can “push” power to the grid and collect it back later?
I’ve a hot water system. It’s tied into the heating and the towel rads.
Not only do I have hot showers, I have warm towels aswell. Costs nothing.
Just ticks along.
Got a 5kw/h system in and it’s great. Not sure about the ROI of a battery though – basically doubles the cost of the system. Instead happy to be getting 20 cent a kw/h sent to the grid. What’s your view OP, having sprung for it?
When you say fully powered, what does that cover? What’s the energy rating of your home?
What’s the performance in winter and what is your primary heating source?

I just put a deposit down yesterday for a 7.2kwh system, didn’t go for a battery as we work from home anyway. Looking forward to reducing my bills.
more, More, MORE !
Cover all the things in solar pannels, though also give people getting the resources for said pannels and battries good pay and safe lives.
Shur add the wind and the wave, be rocking it so yei will.
Was it easy to arrange sending power back to the grid? I asked Electric Ireland about it and they sent me off on a goose chase to get the installers cert and all sorts before they could do anything,
The solar panels were in my house when I bought it and I don’t have any of the details/specs but am confident I’m generating more than I need pretty much from April to Sept and would like to get credit for it somehow.
