I started with solar and battery.
Then it made sense to get an EV to use the surplus summer electricity. So I got the wall charger by the same company as the solar inverter and battery so it would all work seamlessly together.
Looking forward to getting a heat pump as well, but wife is hesitant.
About £13,400 was the cost for our solar (16 panels), battery and car charger (plus backup power facility). A lot of money but it will pay back in about 9 years depending where energy prices go. Solar panels last at least 25 years so you'll get the money back.
Would it increase the value of your house to have them?
Here's a coincidence - Garydoessolar has just released a video on how to calculate future solar savings:
