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.

@skylar @Edent old school immersion heaters and storage heaters still exist, and I think in cases like this could make a lot of sense. My flat has both, and the moment I’m done buying it from the landlord they’re going on smart switches hooked up to Octopus Agile pricing.

@skylar @Edent there’s also just plain old electric radiators. Not sure what the power usage looks like there and how viable it would be to run them off a home battery.

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.
