Doing some maths on our solar panels and battery.
Last month, we only paid for 10% of our electricity!
I'm now crunching the numbers to see just how much the 4.8kWh battery has saved us.
🌞 + 🔋 = 🥰
These aren't the final numbers - but are pretty indicative.
In the last 12 month, having 5kW of solar panels, and a 4.8kWh battery, has saved us a massive two-thirds of our electricity bill!
And that isn't even taking into account how much we sold back to our neighbours.
More maths!
Over the last 12 months, we purchased about 1.2MWh from the grid.
Across the same time, we sold 1.2MWh back to the grid!
I think that means our #solar panels and battery have got our domestic consumption down to #NetZero!
It also knocked about £750 off our electricity bills.
Now I just need to find a way to replace our gas boiler. Sadly can't have a heat pump.
@Edent I wonder how big of a battery one would need to use all of it yourself. I have an inkling that there's enough seasonal variation so that an EV wouldn't be enough.
@Edent if you do figure this out, I would be fascinated to hear how, because I also want shot of our gas boiler and also can't get a heat pump!
@Edent It is a shame you can’t have heat pump. We had ours installed last week.

I'm experimenting with Infrared heating.

Seems to work in small rooms, heats up quickly, relatively low electricity use.
Also have an electric tap for a basin. Again, fairly reasonable. But running a bath with it would be tricky.
@hirvox In January - the worst month - we purchased 192kWh of electricity.
A long range EV is about 70kWh.
I'm trying to do the maths on what size we'd need to save the summer excess.
