as someone that would love to live the nomadic life from the road side and be on a permanent road trip dashing back to england via little plane trips i got think about solar the other day. i know a lot of car companies are starting to do this but i was wondering about right now, i don’t need an integrated solutionsthat’s probably gonna be ages to arrive. i was thinking about today. if i was to pick up parts to give that a go? who’s good at numbers here? who wants to take a stab at it?
let’s say ‘my friend’ was buying a solar panel, say 480 watts of power on the roof and let’s ignore the sunny/cloudy argument and instead think of the car just sitting around for say a week, not doing anything, well let’s say moderate power usage from running the hepa filter at night to provide a nice sleeping experience, but apart from that, sitting there for say 6/8 hrs a day in pretty bright sunny conditions near the equator, let’s say, malta. .. ;)
i’ve seen some maths in other forums saying. ..
85kWh = total battery capacity
300 miles = capable distance traveling at 55mph
85kWh ÷ (300miles ÷ 55mph) = 15.583333 kW
= 8 kettles or toasters running at the same time
now i know that solar panels are not very energy efficient but are getting better but does anybody have the maths chops to come up with a good figure of how long (if it’s even possible to hook into providing enough juice into the outside hookup part) it would take to at least trickle charge a tesla a little bit, is the 480/500w panel just too small to have an impact and would just take ages, does the tesla expect only certain voltages coming in and have power logic if not say a hi power input at the entry level?
like i said at the top. ..
