UK. I installed solar on my roof and put a home battery in last month, and am very happy with the results. It took up-front investment of course and payback times vary between 4-7 years depending on the rates for selling energy back to the grid, but I'm fine with that. My first bill has my electricity cost down about 40% - I installed part way through the month so can't really give consistent figures as yet.
With the solar+home battery, all my domestic electricity usage is easily taken care of. I also took the opportunity to put in a whole home backup, meaning that if there's a power cut the house carries on. Power cuts aren't really a big problem in the UK but little micro ones do happen, and I got fed up of resetting the digital clocks and rebooting everything.
The solar+battery doesnt take care of 100% of my usage though, not by a long way. I've been driving an EV since 2018. I do around 22,000 miles per year, My solar peaks at around 5kWh and is best used to power the house and add to the house's battery capacity. I use about 22kWhs on a round-trip commute, and the home battery is 12.5kWh. The typical max I might need then is 34.5kWh a day, and I also need it overnight - solar isn't going to help me there. My actual pattern is load-shifting: charge both car and home batteries cheaply overnight, use solar+battery through the day on the house and sell the daytime excess to the grid.
On the car alone I have saved around £8-10,000 vs petrol, add in the car maintenance and the savings are even higher. For solar+home battery I don't yet know, not owned it long enough to be able to give good figures but the usage pattern is looking good. If I'm asked about EVs I rarely make an environmental argument - if you can charge at home, the cost argument is so massively in favour of them that's it's barely worth a debate. If you can't - nuance time and more questions to be asked.
I'm not off fossil just yet - still have gas heating. The heat pump equations are a lot trickier to work out - without load shifting it's much more expensive, plus how will it average out over winter when I presumably get less solar to recharge the home battery during the day. So heat pump is the next bit of research rather than my automatic next move. For the rest though - just no argument, the renewable/EV route is just better.
