So a six hours charge adds 3.56 km. This does not seem very useful to me if one uses the car to commute and charges every night anyway.
- hinkley 7y agoYeah I went straight to that line too. That's a little over two miles. But I think the salesmanship could use some work, because they're talking in averages. On a summer day, full sun, you might hit 5 miles of extended range. I wonder if that range number includes or excludes self-discharge rate? How about reduced AC usage on hot days? That number may be more significant than the charging capacity (didn't Toyota do a vent-only solar roof for this reason?) Certain battery chemistries degrade more when they reach a low state of charge, so this trickle charge might end up protecting long-term range retention as the batteries age, maybe? Friend had to have his Prius towed because they stopped driving it for a while.
- gregmac 7y agoUsing 4.43 KM per kWh (based on the plug-in hybrid model [1]), that means the six hour charge is 0.8kWh. At 12 cents per kWh, that means if you get six hours of solar every day (365 days), you'll save about $44 per year in electricity costs. The average person has a car for 6.6 years [2], so that adds up to a whopping $289 in savings (assuming constant electricity prices, anyway). I wonder how much extra the solar panel costs?
