Yes story of my life. Lived a nomadic life, looked at doing these few years ago but been just bought a home there were other priorities.
Cost of adding these is insignificant compared to house price so as long as it doesn't reduce the price we should be ok. I think in 2025 a solar + EV ready home would be lot more appealing to buyers (if not I'll consider this as an altruistic project). If we were to add batteries I know our electric bill would be standing charge only but that increases the cost even further - decisions 😐.
I want to switch to EV but I can't justify the cost of owning a car either - given the low milage.
Solar progresses a lot.
In 6 years, you current solar array may not be as attractive to a home buyer, as new and better panels may be available.
An 8-panel array doesn't even come close to fulfilling the needs of an EV.
8 x 360Wp panels will probably yield less than 2000kWh per year in the UK.
Considering an average EV with a consumption of 150Wh/km, this is the equivalent of 8000 miles per year.
Realistically, including winter driving and charging losses, 7000 miles per year.
Add panel degradation, and it's even less.
So a potential home buyer with an EV would see no merit in such an install.
The install could however meet your home energy needs to a large extent, if you heat with other means than electricity.
So it depends largely on the subsidy situation.
It may be less sexy, but there could be other home improvement projects that could yield greater savings and higher subsidies, like insulation or switching an old gas boiler to a heat pump.
