I have Solar PV installed since 2008 and never ever had to clean the panels...................YMMV

So, no new builds allowed on the northern slopes of hills in Scotland?
Although as I understand things a major component of overall demand is industrial use which won't change.The gap between cheap and day rate on such as Economy 7 is going to reduce as more domestic heating goes over to electric and there is a greater number of EV's
Yeah, I tried that one with my mum as a kid when I didn’t want to take a bath. It didn’t wash if you will excuse a dismal pun on a Sunday morning.The rain keeps ours clean, just dusty at harvest time really.
I've been doing RE since 2008 and keep very much abreast of these things which is not to say I'm an expert....................
The very simple answer here is ensure the new build is built to near passivehaus standard in the first place as this will be money much better spent than investing in sufficient Solar PV + battery storage etc. etc. to cover your needs.
If you insulate it well enough there are some quite cheap A2A wall mounted "heat pumps" which will be provide more than sufficient heat.
In very simple terms Solar PV will only return 10% of your expected output on average through December/ January.
Battery storage - in most cases this doesn't make outright sense on a domestic scale. Believe me I have a Tesla PW2 and 12kW of Solar PV. In your first year a battery system will be 90% efficient at best and it will deteriorate at 3% a year to which you then add the 1% annual deterioration in your Solar PV panels. You'll need to ensure you are on the best TOU tariff you can find as most of the battery charging during the winter season will be by cheap overnight electricity. The gap between cheap and day rate on such as Economy 7 is going to reduce as more domestic heating goes over to electric and there is a greater number of EV's in the population which mitigates still further against any "logic" in installing a battery storage system (even, IMHO, allowing for any reasonable forecastable increase in electricity prices).
Get a trench dug across from the house and lay a suitable SWA cable.
If you want do something green then look to installing Solar PV on the house/ garage roof and install a more environmentally friendly heating system.

Samcat got it but you have nailed it. You're still not getting a like though.
Great idea, you could run the whole island off solar and wind.
