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.
@Edent I’m sure you’ve posted this before, but how much did you pay for all of it, and how long does that make it take to break even?
@gsnedders @Edent I'm interested in this too.
It seems so idyllic but the set up costs are £££

I've written a bit about it before.
Payback depends on how expensive electricity is, and how much your install is.
When leccy prices spiked at the start if Russia's invasion, our payback went down to 5 years. Right now it's about 7ish.
Our install was expensive because we have a complicated roof & old wiring. Our battery manufacturer gave us a discount.
So prices anywhere from £3k to £15k depending on your local market & roof.
@Edent @gsnedders thank you, and yes makes sense! I think where we are, it made financial sense for a while because of subsidies, but said subsidies have subsided and now it feels like biding our time makes a little more sense.
There was/is also huge demand which made the costs and waiting lists for getting stuff installed spike very high.
Still mulling it over, as Germany's energy mix is still pretty dirty at times, with lignite being burned in places. I don't really want to be part of it.
