Energica Experia

Don't know about cost, but can't they make roofs and bonnets out of solar panels.

Different scale of number really. One square metre of solar panel might get 200W if you're lucky and conditions are perfect. So covering the entire roof etc. might just scrape together a kilowatt or two. Couple of bhp...

Of course, you could leave your car parked in the sun for a while. But if you're gonna do that, you may as well save the considerable cost and complexity of making the panels part of the car and create a fixed PV charging point instead right?

To me this just highlights how spectacularly energy dense petrol is. I recently saw a petrol engine described as "a heater which produces motive power as a byproduct", which is an accurate statement. Around two thirds of the petrol you burn generates waste heat, not useful go, but you can afford that level of waste just cause petrol is crazy energy dense and you can carry lots of it about.

So if i parked up on holiday in say, Ilfracombe for 4/5 hrs with solar panel roofing and bonnet, all factory fitted and looking like a panoramic roof, how much % would that put in my Nissan leaf roughly, even very roughly. ?

Judging by the info in this article, not much would be my guess:

If it was more than not much I'm sure the manufacturers would be telling us.

The Lightyear One is a large fastback, with the bonnet, roof and boot clad with 5 m2 (54 sq ft) of solar panels, with a WLTP (Worldwide Harmonised Light Vehicles Test Procedure) range of 725 km (450 miles) and designed with a drag coefficient of Cd=0.20. The company Lightyear claims there are 1,000 solar panels across the car that can add 50–65 km (30–40 miles) of range per day during summer.[3][4]

I've been there and other similar places in the SW for holidays. From my 'summer' experiences, probably 'not much'

Depends if you park in a multistorey or not.

So are we saying green energy is shite unless it's on a grand scale.

[Mr. Dazzle]

No, just that your idea is shite

I'd say your best bet is to use the panels to add storage.
